Storm Updates: Quiet Pulse — Oct 16

Tropical: None · Severe: Quiet · Flood: Marginal

What Changed

• Compared with the morning desk (quiet-pulse-2026-10-16-morning) and the earlier afternoon snapshot: SPC Day 1 Convective Outlook issued 0750 PM CDT Friday, October 16, 2026 (0100Z October 17, valid 170100Z–171200Z) shows NO SEVERE THUNDERSTORM AREAS FORECAST. The prior Slight Risk over the Mid-Atlantic into southern New England has ended as the strong cold front progressed offshore and associated convection weakened or moved offshore.
• Severe Thunderstorm Watches 686 and 687 expired earlier. As of ~0215Z October 17, SPC lists no convective watches currently valid. No mesoscale discussions are in effect for severe potential.
• Preliminary local storm reports from the earlier convective day logged numerous wind damage reports (trees, wires, power lines) primarily across Pennsylvania and into New Jersey, Massachusetts, and Connecticut. No tornado or hail reports. Severe potential is now low.
• WPC Day 1 Excessive Rainfall Outlook (updated 0059Z October 17 / 8:59 PM EDT) maintains Marginal Risk only across portions of southeast Florida. Convection peaked; heavy rainfall coverage declining overnight. Localized urban flash-flood risk may continue a few hours where slow-moving cells drop 2–3 inches in an hour. No Moderate or higher. Prior West Texas Moderate closed.
• Tropical lane unchanged: no tropical storm or hurricane watches or warnings on the U.S. coast or Gulf of America. NHC: no tropical cyclones in the Atlantic, Caribbean, or Gulf; formation not expected next 7 days. Eastern Pacific Hurricane Trudy (approaching Mexico) and remnants of Simon remain offshore Mexico only.

Live Status

As of this Friday evening update to the October 16, 2026 afternoon desk (approximately 8:15 PM PDT / 11:15 PM EDT / 0315Z October 17), the severe weather lane has 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, with the low-topped convective line having weakened or moved offshore. Isolated thunderstorms may linger, but post-frontal conditions limit any severe risk.

Flood remains the only open lane at Marginal over southeast Florida, where high moisture supported earlier heavy rain rates. Coverage is declining overnight. No higher-end excessive rainfall risk is in effect. Non-convective High Wind Warnings continue in parts of southern California and Arizona for gusts to 65–75 mph in mountain passes and foothills, separate from convective threats. No tropical systems threaten U.S. land or the Gulf of America.

Hotspots

Southeast Florida residual: WPC Marginal Risk of excessive rainfall. Localized urban flash flooding possible for a few more hours from slow-moving cells. Convection has peaked and is weakening.

Mid-Atlantic / southern New England just-hit: Earlier Slight Risk and Watches 686/687 produced scattered damaging winds. Multiple tree and wire reports across Pennsylvania into New Jersey and southern New England. Line has exited; residual cleanup only.

Southern California high winds: Ongoing High Wind Warnings in mountain and valley areas with gusts 50–75 mph. Non-convective; potential for tree and power impacts.

Just Hit

The organized Mid-Atlantic Slight Risk window closed this evening. SPC preliminary reports confirm wind damage (trees and wires down) across central and eastern Pennsylvania counties, Hunterdon County NJ, and portions of Massachusetts and Connecticut. No tornado or hail reports. Short-fuse warnings expired with the watches. Prior West Texas Moderate ERO and Midwest residual remain closed.

Pulse Table

Restoration Read

Quiet Pulse on the severe side. Residual work is tree and wire cleanup from the earlier Mid-Atlantic wind event across Pennsylvania into New Jersey and southern New England. Flood remains Marginal only in southeast Florida and does not drive a national water ticket. No tropical claims. Non-convective High Wind Warnings in California and Arizona are separate events. Standard quiet-day posture: check local NWS for any lingering Flood Advisories in Florida and assess residual damage reports. Turn around, don’t drown remains the standing public message.
