Storm Updates: Quiet Pulse — Oct 18

Tropical: None · Severe: Quiet · Flood: Quiet

What Changed

Compared with this morning’s quiet-pulse-2026-10-18-morning desk: SPC Day 1 Convective Outlook (latest 0100Z / 7:44 PM CDT Sunday, October 18, 2026, valid 190100Z–191200Z) continues NO SEVERE THUNDERSTORM AREAS FORECAST. Severe thunderstorms are not expected across the U.S. through tonight. No convective watches or Mesoscale Discussions valid.
WPC Day 1 Excessive Rainfall Outlook (issued ~0100 UTC / 8:57 PM EDT Sunday, October 18, 2026, valid 01Z Mon Oct 19–12Z Mon Oct 19) shows the probability of rainfall exceeding flash flood guidance less than 5 percent. Prior Marginal Risk over southeast Florida has dropped off the Day 1 outlook.
Developing storm-force non-tropical low off the southeast U.S. coast continues. NHC Tropical Weather Outlook gives near 0% chance of subtropical development through 48 hours and ~40% through 7 days. High winds, coastal flooding, and dangerous surf expected along portions of the East Coast. No tropical storm or hurricane watch or warning on the U.S. coast or Gulf of America.
No overnight or daytime local storm reports of severe weather (hail, damaging wind, tornado). Residual coastal and marine products remain. Quiet Pulse holds.

Live Status

As of this Sunday afternoon desk, October 18, 2026 (approximately 8:16 PM PDT / 11:16 PM EDT / 0316Z October 19), the national severe picture remains closed. SPC confirms no severe thunderstorm areas through tonight. An upper-level ridge advances into the southern Appalachians while high pressure stays entrenched from the Gulf Coast states to the Northeast, maintaining dry and cool conditions over much of the continental U.S. Isolated thunderstorms remain possible over south Florida and parts of the Desert Southwest, but no severe threat is forecast.

Water concerns are residual and coastal only. WPC Day 1 probability sits below 5%. River Flood Warnings linger in Florida and Georgia from prior rains. Coastal Flood Warnings and high surf continue along the Outer Banks and adjacent East Coast as the non-tropical low maintains elevated seas and onshore flow. No named tropical cyclone threatens U.S. land. Eastern Pacific Hurricane Trudy remains offshore Mexico with no U.S. impact.

Hotspots

Outer Banks / coastal North Carolina and Virginia: Coastal Flood Warnings, high surf, and rip current risk persist under the developing non-tropical low. Onshore flow and elevated seas continue; no inland severe or flash-flood threat.
Southeast Florida residual: Prior Marginal ERO has dropped. Isolated thunderstorms possible but no severe. Residual standing water and urban ponding from earlier rain; river Flood Warnings on St. Johns and Satilla remain.
Desert Southwest: Isolated thunderstorms possible ahead of a weak upper impulse. Limited moisture and instability preclude severe weather. No flood products active.

Just-Hit

No severe weather reports overnight or today. Preliminary LSRs show marine wind gusts near the Florida Keys and residual flood video in Puerto Rico; nothing convective or severe on the mainland. Prior Mid-Atlantic Slight Risk closed days ago.

Lane	Status	Notes (as of ~8:16 PM PDT / 11:16 PM EDT / 0316Z 19 Oct 2026)
Tropical	None	No named systems threatening U.S. land or Gulf. Non-tropical low off SE coast may acquire subtropical traits (~40% chance later). Pacific Hurricane Trudy offshore Mexico only. No U.S. tropical watches/warnings.
Severe	Quiet	SPC Day 1 (0100Z Oct 19): NO SEVERE THUNDERSTORM AREAS FORECAST. No watches or MDs valid. Thunder limited to southern FL and Southwest.
Flood	Quiet	WPC Day 1 probability <5%. Residual river Flood Warnings (St. Johns near Astor FL, Satilla Atkinson GA). Coastal Flood Warnings NC Outer Banks. No Moderate or higher.

Restoration Read

Primary residual ticket is coastal: high surf, beach erosion, and minor coastal flooding along the Outer Banks and adjacent Mid-Atlantic under the non-tropical low. Inland water is limited to lingering river Flood Warnings in north Florida and southeast Georgia from earlier rains. No convective severe restoration window is open. Verify county-level Coastal Flood and High Surf products before any coastal deployment. Turn around, don’t drown on any residual flooded roads.

What This Is Not

This is a Quiet Pulse. No SPC Slight or higher severe risk, no WPC Moderate or higher excessive rainfall, and no tropical storm or hurricane watch or warning on the U.S. coast or Gulf. The non-tropical low keeps lower-threshold coastal and marine lanes open only.

Looking Ahead One Day

SPC Day 2 (valid Monday) continues no severe thunderstorm areas. WPC Day 2 probability of excessive rainfall remains low. The non-tropical low is expected to meander off the Southeast and Mid-Atlantic coast, maintaining high surf, rip currents, and coastal flooding potential through mid-week. No named storm development is expected in the short term.

Storm Updates: Quiet Pulse — Oct 18 Morning

Tropical: None · Severe: Quiet · Flood: Quiet

What Changed

Compared with the October 17 afternoon pulse and earlier versions of this October 18 morning desk: SPC Day 1 Convective Outlook (latest 0100Z / 7:44 PM CDT Sunday, October 18, 2026, valid 190100Z–191200Z) continues NO SEVERE THUNDERSTORM AREAS FORECAST. Severe thunderstorms are not expected across the U.S. through tonight. No convective watches or Mesoscale Discussions valid as of latest check.
WPC Day 1 Excessive Rainfall Outlook (updated 0100 UTC Monday, October 19, 2026 / 8:57 PM EDT Sunday, valid 01Z Mon Oct 19–12Z Mon Oct 19) shows the probability of rainfall exceeding flash flood guidance less than 5 percent. Prior Marginal Risk over southeast Florida has fully dropped off the Day 1 outlook.
Developing storm-force non-tropical low off the southeast U.S. coast continues. NHC Tropical Weather Outlook (800 PM EDT Sunday, October 18, 2026) gives near 0% chance of subtropical development through 48 hours and 40% through 7 days. High winds, coastal flooding, and dangerous surf expected along portions of the East Coast regardless. No tropical storm or hurricane watch or warning on the U.S. coast or Gulf of America.
Residual NWS Flood Warnings remain on the St. Johns River (near Astor, FL; minor occurring, moderate forecast) and Satilla River (Atkinson, GA; minor). Coastal Flood Warnings and High Surf Advisories continue for Ocracoke Island and portions of coastal North Carolina through Tuesday.
No overnight or recent local storm reports of severe weather. Quiet Pulse holds; water concerns remain residual river and coastal only.

Live Status

As of this Sunday evening update to the morning desk, October 18, 2026 (approximately 8:14 PM PDT / 11:14 PM EDT / 0314Z October 19), the national severe picture remains closed. SPC confirms no severe thunderstorm areas through tonight. An upper-level ridge moves into the southern Appalachians while high pressure remains entrenched from the Gulf Coast states to the Northeast, keeping dry and cool conditions over much of the continental U.S. Isolated thunderstorms possible over south Florida and parts of the Desert Southwest, but no severe threat.

Excessive rainfall risk has cleared from the Day 1 WPC outlook. Residual river Flood Warnings linger in north-central Florida and southeast Georgia from prior rains. Coastal Flood Warnings, High Surf Advisories, and beach hazards persist along the Outer Banks as the developing non-tropical low offshore maintains elevated seas and onshore flow. No named tropical cyclone threatens U.S. land. Eastern Pacific Hurricane Trudy remains offshore Mexico with all coastal warnings discontinued; no U.S. impact.

Restoration Read

Residual river flooding in north-central Florida and southeast Georgia remains a near-term water concern. Coastal flooding, high surf, and beach erosion will continue along the Outer Banks and portions of the East Coast with the developing offshore low into early next week. Wind damage potential (trees, power lines) possible with gusty onshore flow along coastal Florida and the Carolinas. No widespread severe or higher-end flood event is underway. Standard quiet-day posture: monitor residual water and coastal hazards; no new severe or high-end flood tickets expected.

What This Is Not

This is a Quiet Pulse. No SPC Slight or higher severe risk, no WPC Moderate or higher excessive rainfall, and no tropical storm or hurricane watch or warning on the U.S. coast or Gulf.

Storm Updates: Quiet Pulse — Oct 17

Tropical: None · Severe: Quiet · Flood: Slight

What Changed

Compared with this morning’s quiet-pulse-2026-10-17-morning desk: SPC Day 1 Convective Outlook (latest ~0100Z October 18 / 6 PM PDT Saturday, October 17, 2026, valid 180100Z–181200Z) continues NO SEVERE THUNDERSTORM AREAS FORECAST. Severe thunderstorms are not expected across the U.S. through tonight. No convective watches or mesoscale discussions are currently valid.
WPC Day 1 Excessive Rainfall Outlook (updated 0758 UTC Saturday, October 17, 2026, valid 12Z Oct 17–12Z Oct 18) holds the Slight Risk (level 2/4) of excessive rainfall along portions of the Florida East Coast / Gold Coast. Earlier Flash Flood Warnings and residual Flood Advisories (northern Broward / southeast Palm Beach) have expired as of ~6:45 PM EDT. Deep moisture, diurnal heating, and onshore convergence ahead of the cold front still support 2–3 inch-per-hour rates and localized urban flooding potential as cells progress south through tonight.
The developing non-tropical low / Nor’easter off the Carolina coast remains the multi-day story. NHC Tropical Weather Outlook rates formation chance near 0 percent through 48 hours and low (~30 percent) through 7 days. No tropical storm or hurricane watch or warning is in effect for the U.S. coast or Gulf. High winds, coastal flooding, and dangerous surf are expected along portions of the East Coast regardless.
NWS High Wind Warnings and Wind Advisories remain active in Southern California mountains and passes (easterly gusts 45–60 mph through this evening) and along the Outer Banks / coastal North Carolina (north winds 25–40 mph, gusts 45–55 mph through Monday). No new organized severe or Moderate-or-higher flood thresholds have opened.
Nothing material has moved on the severe lane. The picture remains Quiet Pulse.

Live Status

As of the Saturday afternoon desk, October 17, 2026 (approximately 8:14 PM PDT / 11:14 PM EDT / 0314Z October 18), the national severe picture stays closed. SPC confirms no severe thunderstorm areas through tonight and lists no valid convective watches. High pressure dominates much of the CONUS outside residual frontal and coastal activity.

Water remains the primary residual concern. The WPC Slight Risk holds on the Florida East Coast where the cold front is progressing south. Scattered thunderstorms capable of heavy rates and localized urban flash flooding continue through tonight into early Sunday, particularly southeast Florida metro areas from Port St. Lucie through Miami. Earlier short-fuse products have expired; residual drainage continues in poor-drainage urban areas.

The developing coastal low off the Carolinas is building the multi-day wind and coastal flood story. Onshore flow will drive periods of rain, gusty winds (locally 45–55+ mph on the Outer Banks), high surf, rip currents, and beach erosion along the Mid-Atlantic and Outer Banks into early next week. NHC is monitoring possible subtropical development but rates the near-term chance near zero.

Hotspots

Florida East Coast: WPC Slight ERO. Localized flash flooding possible with slow-moving thunderstorms ahead of the cold front. Urban streets, roads, and small streams most vulnerable through tonight.

Outer Banks and coastal North Carolina: NWS Wind Advisories (gusts 45–55 mph) through Monday. Developing Nor’easter brings coastal flooding, high surf, and beach erosion potential.

Southern California: Residual High Wind Warnings and Wind Advisories for easterly/Santa Ana regime in mountains and passes (gusts 45–60 mph) through this evening.

Restoration Read

Localized urban flooding on the Florida East Coast and wind damage potential (trees, power lines, unsecured objects) on the Outer Banks and Southern California mountains remain the near-term concerns. Coastal flooding and beach erosion will build with the Nor’easter into early next week. No widespread severe or higher-end flood event is underway.

What This Is Not

This is a Quiet Pulse. No SPC Slight or higher severe risk, no WPC Moderate or higher excessive rainfall, and no tropical storm or hurricane watch or warning on the U.S. coast or Gulf. The Slight ERO on the Florida East Coast and the developing Nor’easter keep flood and coastal lanes open at lower thresholds only.

Looking Ahead One Day

Sunday holds no severe thunderstorm areas on SPC Day 2. WPC Day 2 carries a Marginal Risk of excessive rainfall over a portion of south Florida. The coastal low continues to influence East Coast winds, surf, and potential flooding into early next week. No tropical development indicated for the U.S. coast or Gulf in the near term.

Tropical: None (Isaias & Rachel dissipated) · Severe: Marginal · Flood: Slight

What Changed

SPC Day 1 Convective Outlook (0100 UTC / 7:47 PM CDT Sunday, October 11, 2026, valid 120100Z–121200Z) holds only a Marginal Risk of severe thunderstorms across parts of the Mid-Atlantic (isolated tornado threat near the coast for a few more hours) and Desert Southwest (isolated severe gusts). No Slight or higher risk remains. Current watches page lists no convective watches valid; Tornado Watch 681 expired earlier.
WPC Day 1 Excessive Rainfall Outlook (updated 0056 UTC Monday, October 12 / 8:56 PM EDT Sunday, October 11, 2026) maintains a Slight Risk of excessive rainfall across parts of the Great Basin and Southwest from residual Rachel moisture. Moderate Risk dropped. Mid-Atlantic reduced to Marginal Risk. Isaias surface low dissipated over West Virginia.
Active Flash Flood Warnings continue in southern Utah, including extensions for Zion National Park (West Central Kane / East Central Washington counties) and the Forsyth burn scar (Central Washington County), with observed flash flooding and considerable damage threat reported.
No tropical storm or hurricane watches or warnings remain in effect for the U.S. coast or Gulf. Post-Tropical Cyclone Isaias has fully dissipated. Remnants of Rachel continue to support residual moisture in the Southwest/Great Basin. Hurricane Simon remains offshore Mexico and does not threaten U.S. land.
Preliminary tornado reports from Sunday afternoon across central and eastern North Carolina (including Candor, Clarendon, Atkinson, Fayetteville area, and near Raleigh) remain under NWS survey. The organized severe window is closed.

Live Status

As of late Sunday evening, October 11, 2026 (around 8:12 p.m. PDT / 11:12 p.m. EDT), the day has entered Quiet Pulse status. SPC holds no Slight or higher convective risk and lists no current watches. Residual Marginal Risk exists for isolated tornadoes near the Mid-Atlantic coast for a few more hours and isolated severe gusts in the Desert Southwest under leftover shear and moisture.

Post-Tropical Cyclone Isaias has dissipated. Its surface low elongated into a trough over West Virginia and was absorbed. Residual rainfall of 1 to 3 inches remains possible overnight across portions of the Central Appalachians into the Mid-Atlantic under a WPC Marginal Risk, but the heavy rain threat is decreasing. Earlier overnight totals of several inches produced flash flooding and landslides in western North Carolina; residual Flood Warnings persist in some elevated areas.

In the Southwest and Great Basin, residual moisture from Post-Tropical Cyclone Rachel supports a WPC Slight Risk of excessive rainfall. The highest residual risk is across western Arizona, with a broader Slight covering northwest Arizona into portions of the Great Basin. Active Flash Flood Warnings cover Zion National Park and the Forsyth burn scar in southern Utah, where thunderstorms have produced heavy rain and observed flash flooding with considerable damage threat. Vulnerable locations include burn scars, slot canyons, dry washes, and urban areas. High Wind Warnings and Wind Advisories remain in effect across parts of Arizona, California, and Nevada.

No tropical storm or hurricane watches or warnings are in effect for the U.S. coast or Gulf of Mexico. All prior tropical products for Isaias and Rachel have been discontinued or reduced to residual flood tracking by WPC.

Hotspots

Southwest / Great Basin residual flood: Primary live residual under WPC Slight Risk from Rachel remnants. Active Flash Flood Warnings in southern Utah (Zion National Park, Forsyth burn scar) with observed flooding and considerable damage threat. Highest residual risk western Arizona into Great Basin. Burn scars, canyons, and urban areas remain vulnerable.

Mid-Atlantic residual severe and flood: Organized window closed after Tornado Watch 681 expired. Multiple preliminary tornadoes in central and eastern North Carolina under survey (Candor, Clarendon, Atkinson, Fayetteville, Raleigh area). Residual Marginal Risk near the coast this evening. WPC Marginal residual rain possible overnight.

Blue Ridge / Central Appalachians residual: Decreasing flood risk as Isaias dissipated. Significant overnight rainfall already produced flash flooding and landslides in western North Carolina. Residual Marginal Risk overnight.

Just Hit

Sunday afternoon tornadoes across central and eastern North Carolina, including observed near Atkinson (Pender County), preliminary or confirmed near Candor (Montgomery — building destroyed), Clarendon (Columbus — structures destroyed), Fayetteville area (Cumberland), Jordan Lake (Chatham), and near Raleigh/Clayton. NWS surveys ongoing. Residual Flash Flood Warnings active in southern Utah from Rachel moisture. Power outages from earlier Isaias impacts continue, with Florida and Alabama still seeing the largest numbers.

Rising Queries

Rising queries tied to today’s residual: “power outage near me” (driven by residual Isaias impacts in the Southeast), “tornado near me” / North Carolina tornado reports, residual flood and flash flood queries for the Southwest and Utah burn scars. Trends data partial this run.

Restoration Read

Coastal wind and surge work from the Friday night Destin landfall remains closed. Immediate residual tickets are inland freshwater extraction and tree/road clearance from Isaias rain in the Appalachians and Mid-Atlantic, plus survey of the afternoon North Carolina tornadoes. On the West Coast, residual flash flooding under the Rachel Slight Risk, especially burn scars and canyons in southern Utah and western Arizona. Distinguish residual Appalachian work from Southwest residual. Power outage restoration continues across the Southeast.

What This Is Not

This is not an active hurricane or tropical-storm warning on the Gulf or Atlantic coast. All Storm Surge and Tropical Storm Warnings for Isaias and Rachel have been discontinued. It is not a plains or Midwest severe outbreak. The organized hazards were the earlier SPC Slight Risk and now-expired Tornado Watch 681 in eastern North Carolina and southeast Virginia (with multiple tornado reports), and the WPC Slight (Moderate dropped) excessive-rainfall risk in the Great Basin and Southwest from Rachel remnants. No new NHC hurricane or storm-surge warning has been issued for U.S. land this run.

Looking Ahead

Isaias remnants are fully dissipated. SPC Day 2 outlook shows no severe thunderstorm areas forecast for Monday. Rachel remnants will continue residual heavy rainfall and gusty winds over the Southwest before further dissipation. Watch the next Storm Tracker update for verification of the Mid-Atlantic tornado reports and any further contraction of the Southwest flood products.

Storm Updates: Isaias Remnants & Rachel — Oct 10 Morning

Tropical: Post-tropical Isaias · TS Watch Rachel · Severe: Slight · Flood: Moderate

What Changed

Isaias is now a post-tropical cyclone near 32.8N 86.8W as of the 10:00 AM CDT NHC final advisory, about 50 miles south of Birmingham, Alabama, moving NNW at 10 mph with maximum sustained winds of 35 mph. All tropical warnings discontinued; WPC continues flood tracking.
SPC Day 1 Slight Risk has shifted eastward from the Panhandle/Big Bend to eastern Georgia into western and southern South Carolina for a tornado threat this afternoon into evening. No convective watches currently in effect.
WPC Day 1 Excessive Rainfall Outlook holds a Moderate Risk for the Southern Appalachians (northeast Georgia into western North Carolina and Upstate South Carolina) and portions of Southern California, down from yesterday’s High near the landfall corridor.
Tropical Storm Rachel is approaching with a Tropical Storm Watch for the Southern California coast from the U.S./Mexico border to the San Diego/Orange County line. Center near 25.5N 119.6W as of 8:00 AM PDT, 520 miles SSW of San Diego, moving NE at 22 mph with 60 mph winds.
Overnight and morning Flash Flood Warnings were active in parts of coastal South Carolina and north-central Georgia. No new NHC hurricane or storm-surge warnings for U.S. land.

Live Status

As of Saturday morning, October 10, 2026, Post-Tropical Cyclone Isaias continues north-northwest across central Alabama. The primary organized threats have shifted to residual heavy rainfall and isolated tornadoes on the eastern side of the circulation, plus the approaching Tropical Storm Rachel on the West Coast. SPC’s 1630 UTC Day 1 Convective Outlook maintains a Slight Risk from eastern Georgia into southern and eastern South Carolina. A couple of tornadoes are possible today over that corridor. WPC’s Day 1 Excessive Rainfall Outlook (updated 0748 UTC) holds Moderate Risk across the Southern Appalachians and over portions of Southern California. No tropical storm or hurricane warnings remain for the U.S. Gulf or Atlantic coast.

Hotspot 1 — Eastern Georgia into Western/Southern South Carolina

SPC Slight Risk covers roughly 34,500 square miles and about 3.5 million people, including Savannah, Columbia, Charleston, North Charleston, and Mount Pleasant. Midday analysis places the remnant circulation over central Alabama with a warm front extending eastward to the South Carolina coast. Destabilization in the warm sector supports scattered storms this afternoon. Enlarged hodographs support storm-scale rotation. A couple of tornadoes are possible primarily during the diurnal heating cycle. A Marginal Risk continues tonight as the warm front advances northward, though uncertainty is high.

Restoration read: tornado swaths remain narrow. Staff as local surveys. Damaging wind gusts are possible with stronger cells. The broader water ticket is the continuing rain bands.

Hotspot 2 — Southern Appalachians

WPC Moderate Risk targets upslope regions from northeast Georgia into the Upstate of South Carolina and western North Carolina. Strong upslope flow with residual Isaias moisture supports heavy precip totals in the 3–5 inch range, with maximum totals of 6–10 inches possible across far western North Carolina into the Upstate of South Carolina. HREF and RRFS show high probabilities for 2-, 3-, and 5-inch amounts. Coastal Carolinas retain potential for isolated 5+ inch totals from coastal convergence. Flash flooding, landslides, and river rises are the primary concerns.

Restoration read: this is the main freshwater flood desk today. Wet drywall, extraction, and structural issues from saturated soils. Prioritize high-terrain and poor-drainage areas. Turn around, don’t drown.

Hotspot 3 — Southern California and Rachel

Tropical Storm Rachel is moving northeast at 22 mph toward northern Baja California and the Southern California border. A Tropical Storm Watch is in effect for the Southern California coast from the U.S./Mexico border northward to the San Diego/Orange County line. WPC Moderate Risk covers portions of Southern California as anomalous moisture is drawn northeast. 1–3 inches, locally higher, are forecast, increasing flash and urban flood potential tonight into Sunday. SPC maintains a Marginal Risk for a few severe wind gusts and low-end tornado potential in the Lower Colorado River Valley into south-central Arizona as the system interacts with shear and moisture. Life-threatening surf and rip currents continue.

Restoration read: urban flooding and wind damage over higher terrain are the tickets. Coastal impacts are primarily surf and minor flooding rather than surge. No widespread structural wind damage expected from tropical-storm-force winds.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this morning
Central Alabama / Isaias center	Residual heavy rain, gusty wind	Post-tropical 35 mph; NHC final advisory	Inland NNW at 10 mph
Eastern GA / western & southern SC	Brief tornadoes, damaging wind	SPC Slight	Active this afternoon into evening
Southern Appalachians (NE GA / W NC / Upstate SC)	Flash flood, 3–10 in possible	WPC Moderate ERO	Upslope heavy rain ongoing
Southern California coast / SW	Heavy rain, TS winds possible, surf	TS Watch; WPC Moderate ERO	Rachel approaching tonight
Desert Southwest / AZ	Severe wind gusts, isolated tornado	SPC Marginal	Increasing with Rachel interaction

What this means for restoration teams

Primary exposure is flash flooding and landslides in the Southern Appalachians from residual Isaias moisture, plus isolated tornado and wind damage in the eastern Georgia / South Carolina Slight Risk zone. In Southern California and the Desert Southwest, Rachel drives urban and flash flooding, strong winds over higher terrain, and coastal surf impacts tonight into Sunday. No widespread hurricane-force wind or storm-surge damage is expected on U.S. land from current systems. Claims will be water-dominant with localized wind/tornado tickets. Stage extraction crews for the Appalachians and monitor San Diego for tonight’s rain onset.

Storm Updates: Isaias Remnants & Rachel — Oct 10

Tropical: Post-Tropical Isaias · Post-Tropical Rachel (TS Watch) · Severe: Marginal · Flood: Moderate

What changed

Tornado Watch 679 expired at 8:00 p.m. EDT. SPC Day 1 Convective Outlook (0100 UTC / 7:57 p.m. CDT) dropped to Marginal Risk for isolated tornado threat this evening across the Carolinas and a few severe wind gusts in the Desert Southwest. No convective watches remain valid.
Post-Tropical Cyclone Isaias as of WPC/NHC Public Advisory 18 at 10:00 p.m. CDT Saturday, October 10, 2026, is near 35.0N 86.7W, moving northeast at 16 mph with maximum sustained winds of 25 mph and minimum pressure 1009 mb. Position advanced well north of the Birmingham area reported earlier; flood threat continues into the Tennessee Valley and Southern Appalachians.
Post-Tropical Cyclone Rachel as of NHC Advisory 56 at 8:00 p.m. PDT is near 30.0N 116.5W, about 40 miles west of Punta Baja, Mexico, and 190 miles south of San Diego, moving north-northeast at 36 mph with maximum sustained winds of 60 mph and pressure 987 mb. Now classified post-tropical; Tropical Storm Watch continues for the Southern California coast from the U.S./Mexico border to the San Diego/Orange County line. Expected to move onshore over northern Baja tonight.
WPC Day 1 Excessive Rainfall Outlook (updated 2331 UTC) maintains Moderate Risk across the Southern Appalachians (northeast Georgia into Upstate South Carolina and western North Carolina) and portions of Southern California. Upslope totals of 3–5+ inches with local 6–10 inches still possible; southern California rain increasing with Rachel moisture.
Active Flash Flood Warnings are in effect for portions of western North Carolina (including Lake Lure / Chimney Rock area in Buncombe, Henderson, Rutherford counties) and central South Carolina (Aiken, Edgefield, Lexington, Saluda). Severe Thunderstorm Warnings for 60 mph wind gusts are active in southern Arizona (Pima, Pinal, Yuma counties) associated with Rachel moisture.

Live status

As of Saturday evening, October 10, 2026 (around 8:00 p.m. PDT / 11:00 p.m. EDT), Post-Tropical Cyclone Isaias continues northeast across central Tennessee toward the Tennessee Valley while weakening. The primary organized threat has shifted to residual heavy rainfall and flash flooding, especially upslope into the Southern Appalachians. SPC notes scattered convection with an isolated tornado threat this evening across parts of the Carolinas along the eastern flank, supported by strong low-level shear, though the Slight Risk and Tornado Watch have expired. WPC Moderate excessive rainfall covers the Southern Appalachians and portions of Southern California.

Post-Tropical Cyclone Rachel is accelerating north-northeast toward northern Baja California and is forecast to move onshore tonight before dissipating early Sunday. Tropical Storm Watch remains for extreme Southern California coastal areas. Moisture from Rachel is driving increasing rainfall and thunderstorms across the Desert Southwest, with Moderate flash flood risk on far southern California and isolated severe wind gusts possible in southern Arizona.

Hotspots

Southern Appalachians (northeast Georgia, Upstate South Carolina, western North Carolina): Primary flood hotspot under the WPC Moderate Risk. Strong upslope flow continues to support heavy precip totals of 3–5+ inches, with maximums of 6–10 inches possible across far western North Carolina into the Upstate of South Carolina. Flash Flood Warnings are active near Lake Lure and Chimney Rock; additional minor flooding and isolated landslides remain possible overnight. Flood Watches cover much of the region.

Carolinas (eastern Georgia residual into South Carolina and southern North Carolina): SPC Marginal Risk for isolated tornado threat this evening with rotating cells in the moist airmass east of the Isaias remnants. Strong low-level shear supports brief tornadoes with semi-discrete cells, mainly across the eastern half of South Carolina into southern North Carolina. Flash Flood Warnings continue in central South Carolina. Threat diminishes overnight as the system moves northeast.

Southern California coast and Desert Southwest: Tropical Storm Watch remains on the San Diego County coastal areas. WPC Moderate Risk of excessive rainfall covers portions of Southern California as Rachel moisture is drawn northeastward; probabilities of 2+ inches highest in far southern California overnight. Burn scars, dry washes, and urban areas most at risk. Severe Thunderstorm Warnings for 60 mph wind gusts are active in southern Arizona. Rachel expected onshore tonight.

Just-hit

Isaias made landfall near Destin, Florida, Friday evening as a Category 2 hurricane with 105 mph winds before rapidly transitioning to post-tropical and weakening across the Florida Panhandle into Alabama and now Tennessee. Residual flash flooding and wind damage occurred Friday night into Saturday. Tornado Watch 679 produced confirmed tornadoes in Screven County, Georgia, and Allendale County, South Carolina, before expiring. Rachel remains offshore with no U.S. landfall yet; the center is expected to approach the Baja/border region tonight. Active Flash Flood Warnings and Severe Thunderstorm Warnings are ongoing.

Pulse table

Region	Main threats	SPC / NWS / WPC level	Status this evening
Southern Appalachians (NE GA / Upstate SC / W NC)	Flash flood, landslides, 3–10 in upslope	WPC Moderate excessive rainfall; active FFWs	Live, ongoing overnight
Carolinas (E SC / S NC)	Isolated tornadoes, residual heavy rain	SPC Marginal (tornado)	Evening threat, diminishing overnight
Southern California coast / Desert Southwest	Heavy rain, flash flood, TS winds possible, severe wind gusts	WPC Moderate; TS Watch (San Diego coastal); active SVR in AZ	Rachel approaching; increasing tonight
Central TN / Isaias center	Residual heavy rain, gusty wind	Post-tropical 25 mph	Inland NE at 16 mph, weakening
Rest of CONUS	No other organized severe	Marginal only in noted areas; no watches	Quiet elsewhere

Restoration read

Primary restoration exposure is flash flooding and potential landslides in the Southern Appalachians from residual Isaias moisture under the Moderate Risk, plus localized tornado and wind damage tickets from earlier in the Georgia–South Carolina zone. In Southern California and the Desert Southwest, Rachel will drive urban and flash flooding, strong winds, and coastal surf impacts overnight into Sunday. No widespread hurricane-force wind or storm-surge damage expected on U.S. land from current systems. Claims will be water-dominant with localized wind/tornado tickets. Sequence water extraction after the heaviest rates pass; do not stage in active flood or warning zones.

What this is not

This is not an active landfalling hurricane or tropical-storm warning on the U.S. Gulf or Atlantic coast. Isaias is post-tropical and inland; all tropical warnings have been discontinued. Rachel is post-tropical with a Tropical Storm Watch for extreme Southern California, not a hurricane or storm-surge warning. Severe risk is Marginal, not Slight or higher, and no convective watches are valid. The organized hazards are the WPC Moderate excessive-rainfall risks in the Southern Appalachians and Southern California, residual isolated tornado threat in the Carolinas, and severe wind gusts in southern Arizona.

Looking ahead one day

Sunday (Day 2): SPC holds a Slight Risk of severe thunderstorms over portions of the Mid-Atlantic (North Carolina, Virginia, southeast Maryland) for a few tornadoes and damaging wind gusts as the Isaias remnants continue northeast. Heavy rain and flash flood potential persist in the Appalachians. Rachel is expected to move inland over northern Baja and the southwestern United States tonight, bringing continued heavy rain, flash flooding, and strong winds to the Southwest and Great Basin before dissipating early Sunday. Isaias remnants are forecast to continue weakening.

Storm Updates: New Mexico Flood Moderate, Dakotas–Appalachians Marginal — Wednesday, September 23, 2026 (Morning)

This is a live Wednesday morning snapshot of local storm-type events across the United States as of the morning of Wednesday, September 23, 2026. Overnight into this morning, the flood desk ran ahead of the severe desk: National Weather Service flash-flood warnings for El Paso County, Texas; Amelia, Cumberland, and Powhatan counties in central Virginia; and a receding western North Carolina pulse around Lake Lure / Bat Cave / Chimney Rock. Those overnight warnings are treated as expired or expiring into this morning. Today’s desks: Storm Prediction Center Marginal Risk for parts of the western Dakotas and the southern Appalachians; Weather Prediction Center Moderate Risk of excessive rainfall across portions of central and eastern New Mexico. No convective watches are currently valid.

These are county- and ZIP-scale thunderstorms and flood pulses, not a U.S. mainland hurricane landfall. There is no named tropical cyclone threatening U.S. land in the current National Hurricane Center picture. Restoration exposure today into tonight is water first in New Mexico and far west Texas, leftover street and creek flooding in central Virginia and the southern Appalachians, and isolated damaging gusts this afternoon if the two Marginal corridors heat. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.

What is live this morning

SPC’s 1300 UTC Day 1 Convective Outlook (issued 7:26 a.m. CDT Wednesday, September 23, 2026; Smith/Mead; valid 231300Z–241200Z) places a Marginal Risk over parts of the western Dakotas and the southern Appalachians. Summary: isolated severe thunderstorms are possible this afternoon across those two corridors. Western Dakotas: mid-level trough moving out of Wyoming/Montana, lee trough, moisture plume off the High Plains, around 1,000 J/kg MLCAPE, isolated marginally severe hail or gusts through early evening. Southern Appalachians: mid-level vorticity maximum sliding southeast from the lower Ohio Valley; dewpoints in the 60s °F; 250–750 J/kg MLCAPE if heating wins against low cloud; strong to locally damaging gusts with the stronger cells. Hail probabilities were removed after the 12 UTC Nashville sounding showed poor 700–500 mb lapse rates (4.8 °C/km).

No convective watches were currently valid as of the SPC watches page update at 09:44:06 UTC Wednesday, September 23, 2026. Most recent watch on the board: 0674. Check spc.noaa.gov/products/watch before you stage.

WPC’s Day 1 Excessive Rainfall Outlook (updated 0832 UTC Wednesday, September 23, 2026; Chenard; valid 12Z Wed–12Z Thu) holds a Moderate Risk across portions of central and eastern New Mexico. Scattered to numerous flash floods are expected; locally significant and life-threatening impacts remain possible on sensitive terrain, urban drainage, and burn scars. A widespread 1–2 inches is generally expected, with localized 2–4 inch swaths likely on top of rain that already fell before 12Z. The Slight risk extends into southeast Arizona and a slice of far west Texas if storms propagate east. Separate flood desks: Slight over portions of eastern Kentucky, eastern Tennessee, and far western North Carolina; Marginal from Ohio into West Virginia and western Virginia/North Carolina; Marginal over south Florida.

Hotspot 1 — Central and eastern New Mexico / far west Texas

Today’s Moderate flood desk and the national headline. A well-defined mid-level shortwave lifts north-northeast across New Mexico with robust upper divergence and the chance of a weak surface low. Cloud cover is the limiter; daytime heating on the eastern edge of the rain shield plus easterly upslope should still support training cells in deep southerly flow. HREF/REFS neighborhood probabilities of more than 3 inches run 40–70% across the eastern half of the Moderate area. Overnight El Paso County already took radar-indicated 0.5–1.5 inch bursts and flash-flood warnings that expired before dawn.

Restoration read: water first. Stage pumps and air movers before the afternoon/evening cores organize. Burn-scar runoff and arroyos fail first. Start extraction the same night if water is inside. Turn around, don’t drown — most flood deaths are in vehicles.

Hotspot 2 — Southern Appalachians / eastern Tennessee

Dual desk: SPC Marginal for isolated damaging gusts, WPC Slight for flash flood on wet ground from eastern Kentucky through eastern Tennessee into far western North Carolina. Extensive low cloud this morning is the uncertainty. If breaks allow 250–750 J/kg MLCAPE, multicells along the inverted trough can put down strong gusts around peak heating. HREF/REFS neighborhood flash-flood-guidance exceedance peaks over eastern Tennessee (above 40% in spots). Overnight, NWS Greenville-Spartanburg held a flash-flood warning into 5:45 a.m. EDT for southeastern Buncombe, northeastern Henderson, southwestern McDowell, northwestern Polk, and northwestern Rutherford counties — 2.5–4 inches already down, waters receding by 3:05 a.m. EDT, Rocky Broad near Bat Cave falling through 6.58 feet.

Restoration read: leftover water plus a second-chance afternoon pulse. Do not treat receding creeks as closed. Stage extractors in eastern Tennessee and western North Carolina; tree and tarp crews only if the gusty cells actually fire.

Hotspot 3 — Western Dakotas

New SPC Marginal added on the 1300 UTC outlook. Mid-level trough crossing Wyoming/Montana reaches the western Dakotas late afternoon and deamplifies toward the Red River Valley by Thursday morning. Lee trough holds a moisture plume north from the central High Plains. Widely scattered storms near the Black Hills and lee trough this afternoon; isolated marginally severe hail or gusts through early evening. No major population centers sit inside the 5% hail contour.

Restoration read: isolated wind and hail, not a regional outbreak. Stage only if you already work the Black Hills / western Dakota corridor. Do not pull crews off the New Mexico water desk for this.

Just hit

Overnight flood, not overnight severe. NWS El Paso/Santa Teresa issued flash-flood warnings for northwestern and central El Paso County into the small hours (radar 0.5–1.5 inches, additional 0.5–1 inch possible; warnings through 3:15 a.m. MDT). Otero Mesa / northwest of Dell City had 2.5–3 inches radar-estimated earlier in the night with rural-road flooding held off Dell City by retention dams. NWS Wakefield: up to 4 inches since 11 p.m. in northwestern Amelia County and up to 5.5 inches since 10 p.m. in western Powhatan County; warnings through 4:00–5:30 a.m. EDT. Western North Carolina pulse receding after 2.5–4 inches.

SPC local storm reports for the 22/1200Z–23/1159Z window carried no tornado and no hail. Wind reports from late Tuesday afternoon remain on the board for Lauderdale County, Alabama (Lexington / Rogersville): power lines down, a brush fire, and a power pole/lines on a vehicle — already noted on yesterday’s afternoon Tygart Media desk. Do not invent additional LSR points.

Pulse table

Region	Main threats	SPC / WPC / NWS level	Status this morning
Central / eastern NM and far west TX	Flash flood, training storms, burn-scar runoff	WPC Moderate	Live flood desk today–Thu 12Z
Southeast AZ	Localized flash flood	WPC Slight	Today
Eastern KY / eastern TN / far western NC	Flash flood + isolated damaging gusts	WPC Slight + SPC Marginal	Afternoon–evening
Western Dakotas / Black Hills	Isolated hail / gusts	SPC Marginal	Late afternoon–early evening
OH into WV / western VA–NC	Localized flash flood on wet soils	WPC Marginal	Today
South Florida	Urban flash flood	WPC Marginal	Local
El Paso / central VA / WNC overnight	Flash flood (expired/expiring FFWs)	Overnight NWS warnings	Aftermath / receding
U.S. mainland tropics	No landfalling named cyclone	NHC quiet for CONUS land	Quiet

What this means for restoration teams

New Mexico and far west Texas remain water jobs if the Moderate risk verifies — extraction, drying, and a 24–48 hour mold clock. Central Virginia and western North Carolina are aftermath from last night plus a second-chance flood axis this afternoon in eastern Tennessee. The Dakotas Marginal is isolated. Do not treat receding overnight warnings as a closed book; soils are primed. Stage before the New Mexico afternoon cores. Start extraction the same night if water is inside. Turn around, don’t drown.

What this is not

This is not a regional derecho and not a U.S. mainland hurricane landfall. There are no tropical cyclones in the Atlantic basin at this hour. Hurricane Polo (Category 4, off southwest Mexico) and Hurricane Odalys (eastern Pacific, well west of Baja) are not CONUS land threats today. Tropical Depression Fifteen-E is a Central Pacific system near Hawaii, not a mainland U.S. landfall. Today’s work, if it verifies, is scattered: New Mexico flash flood, leftover Mid-Atlantic and Appalachian water, isolated Dakotas hail/wind, isolated southern Appalachian gusts.

Looking ahead

SPC Day 2 (Thursday) and Day 3 currently show no severe thunderstorm areas. That does not cancel today’s New Mexico flood problem or this afternoon’s two Marginal corridors. Day 4–8 language is only a possible localized Plains/Mid-Mississippi threat next Monday–Wednesday with weak shear — too unclear for probabilities. Watch the next Storm Tracker update rather than assuming the Moderate rainfall risk is the last line of the week.
