Since August began, the Washington region has felt like a steam bath, culminating in Tuesday’s oppressive high of 97 degrees. But our 10-day run of sweaty weather is about to end. Numerous storms are expected this afternoon and early evening; some could be quite heavy. The National Weather Service has issued a flood watch from 2 p.m. to 11 p. m. in anticipation of the downpours. July and the start of August have been wetter than normal in most parts of the region, which increases the potential for flooding since soils are already wet. In addition to the heavy rain, storms will also bring dangerous lightning and very strong localized wind gusts.
