A flash flood watch will be in effect Tuesday evening through Wednesday afternoon, the National Weather Service said.
A warm, moist air mass moving north Tuesday will mean temperatures near 60 degrees in some areas during the afternoon, but with the mild weather comes rain, NBC Washington Chief Meteorologist Doug Kammerer said.
Some rain is possible by Tuesday evening, but the heaviest rainfall is expected Tuesday night and early Wednesday, Kammerer said. Also expect windier conditions beginning Tuesday afternoon and the possibility of strong-to-severe thunderstorms with gusts up to 50 mph Wednesday morning.
Expect 1-2 inches most places with up to 3 inches in heavier bands of rainfall.
The rain could cause streams and creeks to rise over their banks.
People who live in areas prone to flooding should be prepared. People are warned not to try to get through flooded areas on foot or by car, as the depth and current can be deceiving.
