Storm Updates: Quiet Pulse — Oct 19

Tropical: None · Severe: Marginal · Flood: Marginal

What Changed

• Compared with this morning’s quiet-pulse-2026-10-19-morning pulse table: SPC Day 1 Convective Outlook (latest 0100 UTC / 7:52 PM CDT Monday, October 19, 2026, valid 200100Z–201200Z) holds the Marginal Risk of severe thunderstorms across parts of southeast Arizona and southwest New Mexico. Isolated severe gusts and hail remain possible this evening under 1000–1500 J/kg SBCAPE and ~40 kt shear. No upgrade to Slight or higher. No convective watches issued.
• WPC Day 1 Excessive Rainfall Outlook (updated 0051 UTC Tuesday, October 20, 2026 / ~8:51 PM EDT Monday, valid 01Z–12Z Oct 20) confirms a Marginal Risk of excessive rainfall for portions of the Southwest (southeast Arizona and southwest New Mexico). Hourly rates of 0.5–1 inch possible in stronger cells, mainly urban and terrain-sensitive areas. Matches the morning desk; no Moderate or higher.
• SPC today’s local storm reports (as of the 1200 UTC–1159 UTC page) include 1.25-inch hail 18 N Pirtleville, Cochise County, AZ (2157 UTC), 1.25-inch hail 1 W Deming, Luna County, NM (0010 UTC), downed power lines 5 N Rodeo, Hidalgo County, NM (2235 UTC), and a 77 mph gust 3 NNE Rodeo (2240 UTC). Isolated activity has verified in the Marginal area.
• No tropical storm or hurricane watch or warning on the U.S. coast or Gulf of America. NHC Atlantic Tropical Weather Outlook continues to monitor AL93, a storm-force non-tropical low a few hundred miles off the southeast coast, with low near-term chance of subtropical development. High winds, coastal flooding, and dangerous surf persist along portions of the East Coast. Eastern Pacific Tropical Storm Trudy remains offshore Mexico only and does not threaten the United States. Nothing material moved on the tropical lane.
• Nothing material has moved to open a Slight or higher severe lane or Moderate or higher flood lane. The Marginal severe window is expected to close with loss of heating overnight.

Live Status

As of this Monday afternoon desk update, October 19, 2026 (approximately 8:14 PM PDT / 11:14 PM EDT / 0314Z October 20), the national picture remains a Quiet Pulse. The only open severe lane is the small Marginal Risk over southeast Arizona and southwest New Mexico, where scattered thunderstorms have produced isolated large hail and strong wind gusts this evening. Activity is expected to weaken overnight. No Slight Risk, no watches.

Flood lane carries a Marginal Risk of excessive rainfall over the same Southwest corridor. Isolated flash flooding is possible this evening in urban areas, burn scars, box canyons, and dry washes, but coverage is limited. Residual river Flood Warnings continue, including moderate stage on the St. Johns River near Astor, Florida. Coastal Flood Warnings, High Surf Advisories, and marine Storm/Gale products remain active along portions of the East Coast in association with the offshore non-tropical low. These are coastal and marine, not inland flash-flood events of Moderate or higher intensity.

No named tropical cyclone threatens or has just hit U.S. land. The Atlantic basin has no tropical cyclones. AL93 may briefly acquire subtropical characteristics later this week but is expected to move northeastward away from the coast. Pacific Tropical Storm Trudy is offshore Mexico only.

Hotspots

Southeast Arizona / Southwest New Mexico: Marginal severe and excessive rainfall risk this evening. Isolated 1.25-inch hail and wind damage (downed lines, 77 mph gust) already reported. Cells moving quickly enough to limit widespread flooding but capable of localized issues on burn scars and in urban/terrain areas.

East Coast coastal waters and shoreline: Storm-force non-tropical low (AL93) driving high winds, very rough seas, coastal flooding, and dangerous surf from the Southeast through the Mid-Atlantic and Northeast. Marine Storm and Gale Warnings in effect. Not an inland severe or flash-flood event.

Alaska: Multiple Winter Storm Warnings for heavy snow (5–10 inches in valleys, up to 24–36 inches at higher elevations in the Eastern Alaska Range) with gusty winds. Travel impacts possible through mid-week. Outside the CONUS focus but active.

Just-Hit

SPC local storm reports for the current period document 1.25-inch hail near Pirtleville, AZ, and Deming, NM, plus wind damage and a 77 mph gust near Rodeo, NM, all within the Marginal Risk area this evening. No tornado reports. No widespread flash-flood reports noted beyond residual river stages.

Restoration Read

Quiet Pulse overall. The isolated Marginal severe and excessive rainfall potential in southeast Arizona and southwest New Mexico has produced localized hail and wind reports this evening, with possible limited claims, but coverage is small, no watches support a broader response, and the window is closing overnight. Coastal flooding, high surf, and beach erosion along the East Coast warrant monitoring for overwash and access issues, but these are not inland restoration events. Residual river flooding remains minor and stable. Standard quiet-day posture applies. No widespread severe or higher-end flash flood event is underway. Looking ahead, Pacific moisture is expected to increase flood and isolated severe potential over the Southwest mid-week.

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.

Looking Ahead One Day

Tuesday holds no widespread severe threat on current guidance. The Marginal Risk area in the Southwest is expected to diminish overnight. The non-tropical low continues to influence East Coast winds, surf, and coastal flooding into mid-week. No near-term tropical development expected for the U.S. coast or Gulf. Moisture from the Pacific system may begin increasing rain chances later in the week.
