Flash Floods Possible for Western Gulf Coast and Northeast 09-01 to 09-03
Updated Tue Sep 1st 2026, 8:57am PDT

Our attention this week turns towards potential flash floods and severe storms affecting the Western Gulf Coast and the Northeast. Heavy rains are expected from Tropical Storm EDOUARD as it heads into Southeastern Texas, bringing risks of localized flash flooding. Meanwhile, thunderstorms will be active across the Northern/Central Plains and Lower Great Lakes regions. Additionally, heat will increase across the Midwest and Ohio Valley.

Western Gulf Coast and Northeast

Tuesday and Wednesday promise to be wet as Tropical Storm EDOUARD brings heavy downpours to Galveston,TX and surrounding areas, weakening into a depression. This system is likely to cause flash flooding in urban areas and low-lying spots. In the Northeast, regions including Buffalo,NY and Boston,MA should prepare for thunderstorms and potential flooding.

Northern/Central Plains to Lower Great Lakes

On Tuesday, severe thunderstorms could develop in regions like Kansas City,MO, Omaha,NE, and Des Moines,IA. These storms bring threats of strong winds, hail, and possibly tornadoes. Keep an eye on the skies and take cover if necessary.

Southwest and Rockies

Expect moderate to heavy rain in parts of the Southwest and Rocky Mountains on Tuesday. Residents in Denver,CO and Salt Lake City,UT should be aware of possible rain. This precipitation is due to monsoonal moisture, which is slightly weakening.

Northwest

Rain will arrive on the Northwest Coast late Tuesday, spreading to the Northern Intermountain Region by afternoon. Seattle,WA and Portland,OR will see showers, continuing into Wednesday.

Central and Southern Plains Heat

Finally, a heat wave will expand from the Middle Mississippi Valley into the Ohio Valley and Mid-Atlantic from Tuesday through Thursday. Cities like Louisville,KY and Nashville,TN should prepare for rising temperatures and potential heat advisories.
