Heavy Rainfall and Flooding Concerns in the Southwest; Coastal Low to Impact the East Coast

Deep tropical moisture will lead to widespread showers and thunderstorms capable of producing flash flooding through early next week over the Southwest and Four Corners. A coastal storm is expected to develop off the southeast U.S. coast tonight and is expected to strengthen and bring flooding, dangerous rip currents, gusty winds and heavy rain up much of the East Coast through early next week.

.MARINE... Winds southeast 10 to 15 knots through tonight. A coastal low begins to develop off the Southeast U.S. coast over the weekend, then tracks up the coast toward the Delmarva through the early part of next week. This is going to bring a prolonged period of hazardous marine conditions to all of the waters. A Gale Watch is in effect for all the waters Saturday evening through Sunday night. Frequent wind gusts of 35-45 knots are likely most of Sunday, with occasional gusts around 50 knots possible. A Gale Watch has been extended in time Monday morning and afternoon for the central Chesapeake Bay and Lower Tidal Potomac. Gale conditions will likely continue into Monday as well, which has prompted extensions of the Gale Watch into that period in the central and southern Chesapeake Bay waters and lower Tidal Potomac. Waves during the peak winds of this event could be pretty substantial, reaching heights of 4 to 7 feet over the wider waters of the Chesapeake Bay. Update as of: 307 PM EDT Fri Oct 10 2025
