Overview
- The Storm Prediction Center has placed parts of the region in a Slight Risk for scattered severe thunderstorms, with the main hazard being damaging straight‑line wind gusts.
- Forecasters expect storms to develop late Sunday into Sunday night and move eastward, with timing and storm initiation remaining model‑sensitive so local warnings could change.
- The National Weather Service has issued a Flood Watch for northern New Hampshire because slow‑moving storms could produce very heavy rainfall rates, up to about 3 inches per hour, that can trigger rapid runoff and flash flooding.
- Other threats include isolated hail, frequent lightning, and brief tornado spin‑ups in stronger cells, and conditions should clear to cooler, drier weather early next week.
- Meteorologists are also monitoring a broad low in the western Gulf with a low chance of tropical development that could boost early‑week rain and flooding in southeast Louisiana if it phases with the front.
