Isaias remnants soak Washington Sunday with heavy rain, flood and tornado risk

· N GLOBE

Post-tropical Isaias' remnants blanket the Washington, D.C. region all Sunday with 1–1.5 inches of rain, locally up to 3 inches; evening thunderstorms could bring damaging gusts and brief weak tornadoes, with flash-flood risk along the I-95 corridor.

Why it matters

Hurricane Isaias made landfall Friday night near Destin, Florida as a Category 2 storm (gusts topping 110 mph) and has since become post-tropical. Its remnant cloud shield blankets the Washington, D.C. region all Sunday (Oct. 11), bringing steady rain and a severe-weather threat that will disrupt traffic and outdoor plans across the capital.

Today's weather

According to Capital Weather's midday Sunday update: the D.C. region sees 1–1.5 inches of rain today, with 0.75–3 inches in localized spots; a morning downpour gives way to afternoon showers, with thunderstorms possible Sunday evening bringing damaging gusts and brief weak tornadoes (higher risk southeast of the city). East winds 15–20 mph, gusting 25–30 mph; highs around 65–70°F (18–21°C).

Flood and tornado risk

The FOX Forecast Center and The Weather Channel rate the I-95 corridor from New York to Washington at a level 1-of-4 flash-flood risk, and a 2-of-5 severe-weather threat from Washington to Wilmington, N.C., with gusts to 60 mph and isolated tornadoes possible. Rain eases Monday morning and the afternoon turns sunny, with a dry week ahead.
