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.

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).

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.

As of this late evening update to the October 16, 2026 morning desk (approximately 8:12 PM PDT / 11:12 PM EDT / 0312Z October 17), the severe weather lane is closed. The SPC 0100Z Day 1 outlook confirms no severe thunderstorm areas are forecast through the remainder of the night. A strong cold front has swept the Mid-Atlantic and southern New England; the low-topped convection that produced damaging winds earlier under the Slight Risk and Watches 686/687 has weakened or moved offshore. Sporadic thunderstorm activity may linger briefly in residual areas, but post-frontal conditions limit any further severe potential. Ongoing storms over the Florida Peninsula are generally weakening, with some residual activity possible overnight near the Keys and near-coastal areas.
The flood lane stays at Marginal only over southeast Florida, where seasonably high moisture supported earlier heavy downpours. Coverage is on the decline, though isolated urban flooding remains possible for a few more hours where slow-moving cells drop 2–3 inches in an hour. The progressive nature of the front limited Mid-Atlantic rainfall to minor ponding. No higher-end excessive rainfall risk is in effect. No tropical storm or hurricane watches or warnings affect the U.S. coast or Gulf of America. Separate non-convective High Wind Warnings remain in effect in parts of southern California and Arizona through Saturday.

Restoration Read
With the severe lane closed, the dominant restoration ticket from earlier in the day (Mid-Atlantic into southern New England wind damage under the Slight Risk and Watches 686/687) is now residual. Teams covering the I-95 corridor from the Washington DC metro through Philadelphia, New Jersey, the New York City area, and into southern New England should assess any remaining tree, wire, and power-line damage from the progressive low-topped line. Standard verification of any lingering local warnings applies, but organized severe potential has ended. Flood remains Marginal only in southeast Florida and does not drive a national water response. No tropical surge or coastal claims. Separate non-convective High Wind Warnings in southern California and Arizona are outside the convective scope. Turn around, don’t drown remains the standing message on any flooded roads.

This is the Friday morning Storm Tracker desk for October 9, 2026. Overnight into this morning the organized severe window moved from a small Iowa hail threat to the northern Gulf Coast. The Storm Prediction Center 1300 UTC Day 1 convective outlook, issued 7:57 a.m. CDT, places a Slight Risk of severe thunderstorms across northern Florida, southeast Alabama, and southwest Georgia. The driver is Hurricane Isaias, still offshore. No convective watches are valid. The Weather Prediction Center holds a Moderate Risk of excessive rainfall over southern Alabama, the Florida Panhandle, and southwest Georgia.
Isaias has not made U.S. landfall. National Hurricane Center Intermediate Advisory 11A, corrected, at 7:00 a.m. CDT places the center near 27.0N 87.7W, about 245 miles south of Pensacola and about 170 miles south-southeast of the Mouth of the Mississippi River. Maximum sustained winds are near 110 mph, movement north-northeast near 15 mph, minimum pressure 958 mb. Hurricane-force winds extend outward up to 30 miles. Tropical-storm-force winds extend outward up to 185 miles. NHC says Isaias is on the cusp of major-hurricane strength, is likely to become a major hurricane this morning, and is expected to remain a dangerous hurricane at landfall this evening or tonight inside the warning area. Preparations in the storm-surge and hurricane warning areas should be completed within the next few hours.
These remain county- and ZIP-scale hazards until the core comes ashore. Verify with the National Weather Service for the specific county or ZIP before you roll. Conditions change with the next advisory.
What is live this morning
SPC lists no convective watches currently valid. The watch board’s most recent number, Severe Thunderstorm Watch 676, was a west-central Texas watch from the afternoon of September 30 and expired at midnight CDT that night. It is not a live product. The next Day 1 outlook is scheduled by 1630 UTC. Tornado potential is forecast to increase this afternoon and continue tonight, especially across the Florida Panhandle into southeast Alabama and southwest Georgia, as eastern rainbands spread north and low-level winds and storm-relative helicity strengthen. SPC also notes some enhancement to the wind field, including a convective influence, across southern Alabama near the evolving inverted surface trough late this afternoon into tonight.
The Slight Risk area covers about 25,034 square miles and roughly 1.97 million people. Larger centers named by SPC include Tallahassee, Dothan, Pensacola, Valdosta, and Panama City. The surrounding Marginal Risk covers about 42,289 square miles and roughly 3.98 million people, with larger centers including Jacksonville, Mobile, Savannah, Gainesville, and Albany. NHC tornado language is narrower in time: a tornado risk beginning late this afternoon and continuing tonight in coastal Alabama, the Florida Panhandle, and far southwest Georgia, then continuing Saturday across parts of eastern Alabama, the Florida Panhandle, Georgia, and the Carolinas.
Tropical warnings are the live watch equivalent this morning. A Storm Surge Warning runs from the Mouth of the Mississippi River to the Suwannee River. A Hurricane Warning runs from Ocean Springs, Mississippi, to the Bay/Gulf County line in Florida. Tropical Storm Warnings cover the Jefferson/Plaquemines Parish line in Louisiana to west of Ocean Springs, and the Florida coast east of the Bay/Gulf County line to the Aucilla River. A Storm Surge Watch continues from the Suwannee River to Yankeetown, Florida. Intermediate Advisory 11A corrected the surge values. If the peak coincides with high tide, water could reach 6 to 9 feet above ground from the Alabama/Florida border to Grayton Beach; 4 to 6 feet from Dauphin Island to the Alabama/Florida border and in Mobile Bay; 4 to 7 feet from Grayton Beach to Indian Pass; 4 to 6 feet from Indian Pass to the Steinhatchee River; 3 to 5 feet from Steinhatchee to the Suwannee and from the Mouth of the Mississippi to Dauphin Island; and 2 to 4 feet from the Suwannee to Yankeetown.
Hurricane conditions are expected in the hurricane warning tonight into early Saturday, with tropical storm conditions beginning later today. Tropical storm conditions are expected in the warning areas beginning in the next few hours from the 7:00 a.m. CDT advisory.
Overnight into this morning
The convective day that closed at 1159 UTC this morning did not produce a tornado or wind report on the SPC filtered log. It did produce hail. The overnight reports sit on yesterday’s Iowa Marginal Risk, not on the Gulf. SPC lists 1.00-inch hail 2 miles south of Sioux Center, Iowa, at 0226 UTC; 1.50-inch hail at Panora in Guthrie County at 0237 UTC; 1.00-inch hail at Orange City; 1.00-inch hail at Redfield in Dallas County at 0305 UTC; 1.50-inch hail at Ireton; 1.25-inch hail at Wall Lake in Sac County at 0320 UTC; 1.50-inch hail at Cherokee at 0337 UTC; 1.25-inch hail west of Norwalk in Warren County at 0401 UTC; 1.50-inch hail at Alcester in Union County, South Dakota, at 0532 UTC; and a measured 1.00-inch hail on the 200 block of Lloyd Street in Lake City, Calhoun County, at 0552 UTC. Those are preliminary local storm reports. They are the just-hit record from last night. They are not a continuing Iowa watch.
Thursday evening flash-flood products on the national summary were short-fused and have expired for this desk. Jacksonville issued a flash flood warning for east-central Nassau County, including Fernandina Beach, Yulee, and Amelia City, at 5:19 p.m. EDT Thursday, with 2 to 4 inches already down and another 1 to 2 inches possible, until 7:00 p.m. EDT. Honolulu issued a flash flood warning for Oahu at 10:21 a.m. HST Thursday after water over Kamehameha Highway on the North Shore, until 1:15 p.m. HST. Neither is a live warning this morning. Storm-surge warnings on the northern Gulf Coast from Thursday evening remain the standing coastal product and match the NHC warning.
Water pulse
WPC’s Day 1 Excessive Rainfall Outlook, updated 0825 UTC and discussed at 4:28 a.m. EDT, keeps a Moderate Risk of excessive rainfall in southern Alabama, the Florida Panhandle, and southwest Georgia, valid 12 UTC Friday through 12 UTC Saturday. WPC says numerous instances of flash flooding are likely, some significant, and that the outlook is consistent with the previous forecast. Heavier rain rates ramp up closer to landfall and after, as the strongest instability in the southeast quadrant reaches the coast. The flash-flood threat should increase markedly from late Friday afternoon into Friday night.
Two corridors matter. Inner-core and eyewall rain is the coastal problem in southern Alabama and the western Florida Panhandle, highest closest to the coast. Farther east, a training band along the instability gradient can sit about 200 miles east of the landfall point. WPC says that band has better access to instability and deep tropical moisture, can produce double-digit totals of 10 inches or more if it trains, and may hold the event maximum. The Moderate Risk was nudged slightly east, including the chance the band sets up east of Tallahassee at times, and extended into southwest Georgia at least 100 miles inland. Inland along the track into eastern Mississippi and central Alabama stays at Slight for now, because shear is increasing and the inland flash-flood reach depends on whether the core holds together. NHC rainfall through the weekend is 4 to 8 inches across southern Alabama, the Florida Panhandle and Big Bend, and southwest Georgia, with localized totals up to 15 inches in banding across the Panhandle and Big Bend. Much of the rest of the Southeast is forecast at 2 to 5 inches, with localized amounts up to 10 inches possible in the southern Appalachians and coastal Carolinas. River flooding is also expected, some of it significant.

Restoration read
This morning is still a prep window, and it is closing. The first exposure on the northern Gulf Coast is life-safety surge and wind, not a ticket count. Hurricane-force wind is a small radius, about 30 miles from the center, so structural wind damage will be concentrated near the landfall point inside the hurricane warning from Ocean Springs to the Bay/Gulf County line. Tropical-storm-force wind reaches much farther, out to about 185 miles, and that is the power, tree, and soft-roof radius that will show up well away from the eye. Surge of 6 to 9 feet above ground, if it verifies from the Alabama/Florida border to Grayton Beach, is the coastal floor and marina problem. It is not a uniform flood across the whole warning.
Water is the broader restoration pulse, and it is offset from the center. WPC is explicit that the training band east of landfall, on the order of 200 miles east, can hold the rainfall maximum. Crews that staff only the landfall pin will miss the flash-flood ground in the Florida Big Bend, around Tallahassee, and into southwest Georgia. Saturated roads, underpasses, and small creeks are the overnight into Saturday problem. River flooding follows. Iowa hail is a closed overnight note: roof and vehicle checks in Guthrie, Sioux, Sac, Cherokee, Dallas, Warren, and Calhoun counties, and at Alcester, South Dakota, not a new dispatch.
Do not treat a Slight Risk as a watch. SPC has not issued a tornado watch yet. The tornado window in NHC language opens late this afternoon in coastal Alabama, the Panhandle, and far southwest Georgia. If a watch goes up on the 1630 UTC outlook cycle, that is the afternoon desk’s update, not a fact this morning.
Looking ahead
Landfall is forecast tonight or early Saturday inside the hurricane warning. After landfall, gusty winds are expected well inland over the Southeast as the wind field grows in the trough interaction. Saturday’s tornado threat shifts across eastern Alabama, the Florida Panhandle, Georgia, and the Carolinas. Rain of 2 to 5 inches, locally 10, reaches the southern Appalachians and coastal Carolinas through the weekend. The next complete NHC advisory is scheduled for 10:00 a.m. CDT. The next SPC Day 1 outlook is scheduled by 1630 UTC.
This is a morning snapshot from official National Weather Service, Storm Prediction Center, Weather Prediction Center, and National Hurricane Center products. It is not a warning, not a watch, and not a substitute for local emergency management. Hurricane, storm-surge, tropical-storm, tornado, and flash-flood products can be issued or canceled between desk cycles. Check weather.gov and hurricanes.gov for the county or ZIP before you travel or stage.
This is the Thursday morning Storm Tracker desk for October 8, 2026. Overnight into this morning the organized severe window stayed closed, then the 1300 UTC Day 1 outlook opened two small marginal areas. The live story is not a plains watch. It is Hurricane Isaias, now an 80 mph hurricane in the central Gulf of America, with hurricane and storm surge warnings already up on the northern Gulf Coast for a late Friday or early Saturday landfall.
The Storm Prediction Center 1300 UTC Day 1 convective outlook, updated 7:46 a.m. CDT and valid 1300 UTC Thursday through 1200 UTC Friday, carries a Marginal Risk across parts of the Florida Peninsula and across parts of the Upper Midwest and middle Missouri Valley. SPC had no convective watches in effect at 13:21 UTC. The most recently issued watch is 676, and it is not valid. Today’s SPC storm-report page, covering 1200 UTC Thursday through 1159 UTC Friday, had received no tornado, hail, or wind reports at the morning scan. The overnight 0100 UTC Day 1 outlook, issued 7:58 p.m. CDT Wednesday, carried no severe thunderstorm areas through daybreak.
These are county-scale warnings and a named tropical cyclone, not a scattered high-plains hail chase. Restoration exposure through Saturday is surge, wind, and interior water on the central Gulf Coast, plus a localized Florida flood pulse that is already on saturated ground. Conditions change with the next advisory. Verify with the National Weather Service for the specific county or ZIP before you roll.
What is live this morning
National Hurricane Center Intermediate Advisory 7A, 7:00 a.m. CDT, places Hurricane Isaias near 23.7N 90.6W, about 175 miles north-northwest of Progreso, Mexico, and about 385 miles south-southwest of the mouth of the Mississippi River. Maximum sustained winds are near 80 mph. Minimum central pressure is 975 mb. Motion is east-northeast at 9 mph. Hurricane-force winds extend outward up to 15 miles from the center. Tropical-storm-force winds extend outward up to 90 miles. Hurricane Hunters were investigating the storm at advisory time.
A Storm Surge Warning is in effect from the mouth of the Mississippi River to the Steinhatchee River, Florida. A Hurricane Warning runs from Ocean Springs, Mississippi, to the Bay/Gulf County line, Florida. A Tropical Storm Warning covers the Jefferson/Plaquemines Parish line, Louisiana, to west of Ocean Springs, and east of the Bay/Gulf County line to the Aucilla River, Florida. A Storm Surge Watch continues from the Steinhatchee River to Yankeetown, Florida. No watch or warning changes were made on the 7 a.m. intermediate advisory. Preparations along the warning area should be rushed to completion today. Landfall is forecast along the U.S. northern Gulf Coast inside the warning area late Friday or early Saturday. Additional strengthening is expected through early Friday, and Isaias is forecast to remain a dangerous hurricane as it approaches the coast Friday night.
Peak surge heights above ground, if the peak coincides with high tide: Ocean Springs to Indian Pass, 5 to 7 feet; Mobile Bay, 5 to 7 feet; mouth of the Mississippi River to Ocean Springs, 3 to 5 feet; Indian Pass to the Steinhatchee River, 4 to 6 feet; Steinhatchee River to Yankeetown, 2 to 4 feet; Lake Pontchartrain, 1 to 3 feet. The deepest water is expected along the immediate coast near and east of landfall, with large waves on top of the surge.
Hotspot 1 — Northern Gulf Coast hurricane warning
This is the warning, not a watch. Hurricane conditions are expected inside the Hurricane Warning Friday night into early Saturday, with tropical-storm conditions beginning Friday. Cities and counties on the warning corridor include Ocean Springs and the Mississippi coast east of there, coastal Alabama including Mobile Bay, and the Florida Panhandle through Bay County: Panama City, Panama City Beach, Mexico Beach, and Lynn Haven sit inside the local hurricane and storm surge warning language from the Tallahassee office. Tropical-storm conditions are expected farther west into southeast Louisiana and farther east toward the Aucilla River.
Rainfall from Friday through the weekend is forecast at 3 to 7 inches, with localized totals up to 10 inches, from far southeastern Louisiana to the Florida Panhandle. Amounts of 1 to 3 inches, locally up to 5 inches, are possible across much of the Southeast as far north as the Tennessee Valley and the Carolinas. Flash and urban flooding, and isolated river flooding, are possible. Isolated tornadoes are possible Friday night in coastal Alabama, the Florida Panhandle, and far southwestern Georgia, then Saturday across eastern Alabama, Georgia, and northern Florida.
Restoration read: surge and wind first, water second. Roof, siding, awning, and porch damage is the Friday-night ticket where hurricane-force gusts verify. Surge flooding is a life-safety event before it is a drying job. Do not stage crews into the warning area once tropical-storm-force winds arrive. The interior water clock starts after the surge recedes and rainfall trains inland Saturday into the Tennessee Valley. Photograph only if it is safe and daylight remains.
Hotspot 2 — Florida Peninsula marginal tornado and flood
SPC’s categorical Marginal Risk on the middle Florida Peninsula is a 2 percent tornado probability, not a wind or hail area. Population centers named on the tornado graphic include Tampa, St. Petersburg, Clearwater, Lakeland, and Brandon, about 4.2 million people inside roughly 7,900 square miles. Storms are focusing along a convectively reinforced front from the eastern Gulf across the middle Peninsula. Tampa Bay radar wind profiles sampled weak low-level flow with moderate directional turning and a speed increase above 3 km, netting about 25 to 30 knots of effective shear. SPC notes a low-confidence chance of a near-shore waterspout or a brief tornado inland near the front. That is not a high-confidence severe day. It is a brief-spin risk on an already wet front.
The Weather Prediction Center Day 1 Excessive Rainfall Outlook, updated 0821 UTC and valid 12 UTC Thursday through 12 UTC Friday, keeps a Marginal Risk over much of the Florida Peninsula. A stalled front is still the driver. North Florida soils are fully saturated after consecutive rain days, so light to moderate rain converts to runoff. Isolated flash flooding is most likely where convection develops over a larger city such as Tampa or Orlando. Broader issues are poor drainage and urban streets, not a regional river flood. No Slight or Moderate excessive-rainfall area is on the Day 1 map.
Restoration read: Florida today is extraction on saturated ground and a brief tornado survey if one verifies near the front. It is not the Gulf landfall. Keep the Peninsula crew separate from the Panhandle warning.
Hotspot 3 — Iowa and the middle Missouri Valley tonight
The second Marginal Risk is elevated hail, not a daytime surface outbreak. SPC places a 5 percent hail probability over about 30,100 square miles and 1.7 million people, including Des Moines, Sioux City, Waterloo, Ames, and West Des Moines. Isolated to widely scattered elevated thunderstorms are expected tonight as warm advection and isentropic ascent increase northeast of a warm front. Moisture is modest. Mid-level moistening on the edge of the Plains elevated mixed layer is enough for a hail threat, not a damaging-wind area. No wind probabilities were drawn on the 1300 UTC outlook.
Restoration read: this is an overnight hail ticket if it verifies, roof and auto glass, not a watch-box wind event. Do not staff it like a Great Lakes slight risk. Check local warnings after dark before rolling.
Watches that expired versus what is still live
No SPC convective watch is live this morning. Wednesday’s afternoon desk already had a closed severe window, and the 0100 UTC update kept that closed through daybreak. The products that are live are tropical, not convective: the hurricane warning, the storm surge warning, the tropical storm warnings, and the storm surge watch listed above. Alaska winter-storm and high-wind warnings are in effect for parts of the Brooks Range, the Bering Strait coast, and the Alaska Range. Those are not the CONUS restoration pulse this desk is tracking.
Just-hit reports from last night are thin. SPC logged no severe reports on the Thursday page at the morning scan, consistent with the no-severe overnight outlook. The just-hit story is intensification, not damage: Isaias was a 65 mph tropical storm on Wednesday afternoon’s desk and is an 80 mph hurricane at 7 a.m. CDT, pressure down to 975 mb. No U.S. landfall has occurred. Swells reach the Yucatan later today and the Gulf Coast on Friday.

What this means for restoration teams
Hurricane-force wind on a compact core, only about 15 miles of hurricane-force wind from the center at advisory time, is a narrow damage swath if the core holds, not a multi-state derecho. Tropical-storm winds and surge cover a much wider coast. A 5-to-7-foot surge is structural and contents loss on the immediate coast before it is a dry-out. Rainfall of 3 to 7 inches, locally 10, on the central Gulf Coast is the Saturday water ticket inland of the surge line. Friday-night tornadoes on the Alabama and Panhandle coast are a local survey, not the regional event.
For teams near the Hurricane Warning: finish exterior prep today. Do not plan a Friday-night arrival. Property owners inside the surge warning should follow local evacuation orders. The Florida Peninsula marginal is a separate, smaller desk. Iowa hail is an overnight check, not a morning dispatch.
What this is not
This is not a Slight or Enhanced severe-thunderstorm risk, and it is not an active SPC watch. It is also not a landfall that has already happened. Isaias is still about 385 miles south-southwest of the mouth of the Mississippi. East Pacific Tropical Storm Simon is not a U.S. land threat this morning. The work, if it verifies, arrives Friday night into Saturday on the northern Gulf Coast, with a smaller Florida flood and tornado pulse today and an elevated hail chance in Iowa tonight.
Looking ahead
The next complete NHC advisory is scheduled for 10:00 a.m. CDT. Track, intensity, and the warning endpoints can shift before Friday night. SPC’s Day 4–8 outlook, issued 3:21 a.m. CDT, keeps potential too low for a 15 percent severe area through the period, but notes a Sunday shortwave tied to the tropical cyclone crossing the Tennessee and Ohio Valleys toward the Mid-Atlantic, with low predictability on destabilization, and a separate western trough later in the week. The afternoon desk should update the advisory, not assume this morning’s warning line is final.
Sources and how to verify
Primary sources: NOAA Storm Prediction Center 1300 UTC Day 1 Convective Outlook for Thursday, October 8, 2026, and the 0100 UTC overnight outlook; SPC current watches page (no watches valid, updated 13:21 UTC); SPC storm reports for October 8; Weather Prediction Center Day 1 Excessive Rainfall Outlook, updated 0821 UTC; National Hurricane Center Intermediate Advisory 7A for Hurricane Isaias, 7:00 a.m. CDT. Prior desk: Wednesday, October 7 afternoon storm updates.
Wednesday morning desk. Florida owns the water. The organized severe window is closed. Not an NWS warning.
This is the Wednesday morning Storm Tracker desk for October 7, 2026. Overnight into this morning the severe board stayed empty. The Storm Prediction Center 1300 UTC Day 1 Convective Outlook, issued 7:43 a.m. CDT, has no severe thunderstorm areas forecast. Organized severe thunderstorms are unlikely across the United States today and tonight. No convective watches are valid. The Weather Prediction Center holds a Marginal Risk of excessive rainfall for much of the Florida Peninsula through 12 UTC Thursday, after a live flood warning on the Jacksonville metro from overnight rain.
These are county- and ZIP-scale flood and river tickets, not a plains outbreak and not a U.S. mainland hurricane landfall this morning. Tropical Storm Isaias is a Friday northern Gulf planning note. Conditions change fast. Verify with the National Weather Service for the specific county or ZIP before you roll.
What is live this morning
SPC language at 7:43 a.m. CDT: no tornado, wind, or hail risk areas. General thunderstorm areas remain drawn over parts of Florida, the northern tier into northern New York, and scattered western terrain, but that is thunder coverage, not a severe category. The most recent convective watch on the SPC board is Severe Thunderstorm Watch 676, issued September 30 for west-central Texas. It expired at midnight CDT that night. Nothing replaced it overnight.
West-central Florida is the place SPC is still watching, even with probabilities withheld. The setup looks like yesterday: a weak surface wave and a front from the northeast Gulf east-northeast across the middle of the Peninsula. Showers and some thunderstorms were already on either side of the front early this morning. The 12 UTC Tampa Bay sounding sampled 2.53 inches of precipitable water, with 70s dewpoints near and south of the front. Cloud cover and ongoing rain keep lapse rates poor and buoyancy thin. Effective shear is generally 25 knots or less. Some low-level veering could support a transient supercell, and waterspout potential exists offshore. SPC says it is unclear whether a tornadic waterspout reaches the west-central Peninsula or whether supercells develop inland. Severe risk stays low unless a later outlook adds probabilities. The next Day 1 update is scheduled by 1630 UTC.
Northern New York is the other convective note. Isolated low-topped thunderstorms are possible late today and more so tonight as an amplifying upper trough and a cold front approach. Buoyancy is limited. Gusty winds are plausible tonight as low- and mid-level flow increases and lapse rates steepen above the boundary layer. That is a local wind and lightning desk, not a watch.
Hotspot 1 — Florida Peninsula flood pulse
WPC’s Day 1 Excessive Rainfall Outlook, updated 0831 UTC (5:03 a.m. EDT), keeps a Marginal Risk over much of the Florida Peninsula, valid 12 UTC Wednesday through 12 UTC Thursday. A slow, strong front stays draped across the northern Peninsula. South of it, precipitable water is above 2.25 inches. Light to moderate rain continues along I-4 and generally south of I-10, with localized convection that can stall. The Marginal is there because a cell that hits an urban or flood-prone spot can exceed flash-flood guidance. Four Corners showers this afternoon stay sub-Marginal on the WPC discussion.
The overnight ticket that already verified is Jacksonville. The National Weather Service in Jacksonville issued a Flood Warning at 5:20 a.m. EDT for southeastern Duval County and north-central St. Johns County, in effect until 8:15 a.m. EDT. Doppler radar showed heavy rain from thunderstorms. Between 3 and 7 inches had fallen, with up to 2 more inches possible. Locations named in the warning include Jacksonville, Arlington, Ponte Vedra Beach, Jacksonville Beach, Atlantic Beach, Neptune Beach, Baymeadows, UNF, and Craig Field. Streams were still rising from the last 12 hours of runoff. That warning is short-fuse urban water, not a multi-day river crest.
River warnings are the slower desk. NWS Tampa Bay issued a Flood Warning at 6:34 a.m. EDT for the Withlacoochee at U.S. 41 Dunnellon, affecting Levy, Marion, and Citrus counties, until further notice. Minor flooding. Stage was 28.2 feet at 5:45 a.m. EDT, at flood stage, with docks and boat ramps flooding. The office tied the elevated stage to hydrilla acting like a dam along a 4.5-mile stretch between U.S. 41 and Lake Rousseau, with levels expected to stay steady or rise if more rain falls in the basin. NWS Melbourne continues a Flood Warning for the St. Johns River near Astor, affecting Volusia and Lake counties. At 8:30 p.m. EDT Tuesday the stage was 2.4 feet, flood stage 2.3 feet, with a rise toward 2.7 feet late this week. Docks, ramps, and low roads nearest the river are the impact language.
Restoration read: Jacksonville Beach through Arlington is the just-hit extraction window if water is inside. Do not wait on a severe watch that is not coming. Dunnellon and Astor are river-bottom and marina tickets, not a new convective outbreak. West-central Florida stays a monitor for a brief waterspout or a stalled cell, not a hail board.
Hotspot 2 — Iowa river aftermath
The Quad Cities office extended minor flood warnings Tuesday evening on the Cedar and Iowa rivers. Cedar River near Conesville, affecting Muscatine and Louisa counties, was at 13.9 feet at 8 p.m. CDT Tuesday, cresting, flood stage 13.0 feet, warning until late Thursday night, with water affecting residences along County Road F70. Iowa River at Oakville was 11.1 feet, flood stage 11.0, expected below flood stage Thursday afternoon. Iowa River at Wapello was 21.5 feet, flood stage 21.0, until Friday morning, with agricultural land and secondary roads in Wapello Bottoms in the impact language. Iowa River at Marengo, Iowa and Benton counties, remains under a warning until late Friday night. These are falling or cresting river tickets from earlier rain, not a new SPC day.
Restoration read: drying and access on the bottoms, not a hail or wind callout. Do not pull a plains severe crew for Louisa County this morning.
Just hit
SPC local storm reports for the window from 1200 UTC Tuesday through 1159 UTC Wednesday show no tornado, hail, or wind reports. Today’s report page, which opened at 1200 UTC Wednesday, is also empty as of this desk. Yesterday’s Marginal tornado area on the west-central Florida coast, and Mesoscale Discussion 2346, did not produce a logged land report. The 0100 UTC Tuesday-night outlook had already pulled severe probabilities after rotating storms weakened approaching the western peninsula shoreline.
The verified overnight hit is water, not wind: 3 to 7 inches in southeastern Duval and north-central St. Johns, with the Jacksonville flood warning still live into the morning commute. Panhandle work from earlier in the week remains aftermath. Nothing new was logged from a convective watch, because none was in effect.
Tropical note — Isaias, not a landfall
National Hurricane Center Advisory 3 at 4:00 a.m. CDT upgraded Tropical Depression Nine to Tropical Storm Isaias. Center near 22.0 N, 94.1 W, about 285 miles west of Progreso, Mexico, and about 580 miles southwest of the mouth of the Mississippi River. Movement east-northeast near 8 mph. Maximum sustained winds near 40 mph. Minimum pressure 1004 mb. Tropical-storm-force winds extend outward up to 45 miles. No coastal watches or warnings are in effect. NHC says interests on the Yucatan Peninsula and the U.S. northern Gulf Coast should monitor the storm, and that hurricane watches will likely be required for a portion of the northern Gulf coast later today.
Forecast track: pass north of the Yucatan on Thursday and approach the U.S. northern Gulf Coast on Friday. Rapid strengthening is forecast, with Isaias expected to become a hurricane by Thursday. Rainfall on U.S. land is a Friday-through-weekend item, not this morning’s ticket: 3 to 6 inches, localized up to 10, from far southeastern Louisiana to the Florida Panhandle, and 1 to 3 inches, localized up to 5, across much of the Southeast as far north as the Tennessee Valley and the Carolinas. Flash, urban, and isolated river flooding will be possible then. Swells reach the Gulf Coast late this week. Offshore hurricane and tropical-storm warnings are already on Gulf marine zones. That is marine, not a coastal warning for land. Hurricane Rachel is in the eastern Pacific, well west of Baja California, and is not a U.S. land threat this morning.

What this means for restoration teams
This morning’s work is water that already fell. Three to seven inches in southeastern Duval and north-central St. Johns is wet drywall, soaked lower cabinets, and a 24–48 hour mold clock if water crossed the threshold. Standing water on Beach Boulevard corridors and low lots is an access problem before it is a rebuild. Photograph in daylight only if it is safe. Turn around, don’t drown.
Dunnellon and Astor are slower. Marina docks, ramps, and the first roads off the river are the exposure, not a roof-tarping line. Iowa bottoms are the same class of ticket farther north: agricultural land and secondary roads, residences along County Road F70 near Conesville if the stage holds. Do not staff those as a severe-wind event.
West-central Florida does not earn a severe board until SPC draws one. If a waterspout comes ashore, it is a narrow coastal survey, not a regional callout. Northern New York gusts tonight, if they verify, are tree-on-line and light roof work on a limited buoyancy profile.
Isaias is not a roll-today storm. Hurricane watches may come up later today for part of the northern Gulf coast. Friday is the approach day on the current NHC track, with the heavier rain from southeastern Louisiana to the Florida Panhandle after that. Stage the planning conversation. Do not pull crews off the Jacksonville flood warning for a center that is still about 580 miles southwest of the Mississippi mouth.
What this is not
This is not a Slight Risk day and not a convective watch morning. SPC logged no severe reports overnight. It is not a U.S. mainland hurricane landfall. Offshore hurricane warnings on Gulf marine zones are for waters, not for a coastal county warning yet. The local-storm pattern this desk should staff is Florida urban water, two Florida river gauges, and leftover Iowa river flooding.
Looking ahead
SPC’s Day 2 outlook, issued late Tuesday night, also has no severe thunderstorm areas for Thursday. Isolated low-topped storms are possible from the upper Hudson Valley into Maine, with very small hail not ruled out under cold temperatures aloft. Florida keeps scattered afternoon storms in rich moisture as Isaias strengthens over the central Gulf, but Thursday severe is not expected on that outlook because of weak shear and poor lapse rates. The change to watch is NHC: hurricane watches likely later today for a portion of the northern Gulf coast, then the Friday approach. The afternoon desk should say whether SPC added a Florida severe probability and whether a land watch is up.
