issued a flash flood watch for portions of Maryland...central and Northern Virginia...the eastern panhandle of West Virginia
and
Washington DC from noon through 11 pm this evening.
* Widespread rainfall rates of one to two inches per hour
can be expected from afternoon and evening thunderstorms.
* Excessive rainfall could cause creeks and streams to rise quickly out of their banks and could flood low-lying and
urban areas...particularly those that have had recent significant
rainfall.
A flash flood watch means that conditions may develop that
lead to flash flooding. Flash flooding is a very dangerous situation. You
should monitor later forecasts and be prepared to take action should flash
flood warnings be issued.
