... Flash Flood Watch in effect through late tonight...

The National Weather Service in Sterling Virginia has issued a

* Flash Flood Watch for portions of Maryland, the District of
Columbia, and Virginia, including the following areas, in
Maryland, Anne Arundel, Calvert, Carroll, central and
southeast Howard, central and southeast Montgomery, Charles,

northern Fauquier, Orange, Prince William/Manassas/Manassas
Park, Rappahannock, southern Fauquier, Spotsylvania, Stafford,
and western Loudoun.

* Through late tonight

* thunderstorms with heavy rainfall are expected across the region
this afternoon and evening. The potential for training
thunderstorms exists, which could result in several inches of
rain in one to two hours. Soils are already very moist, meaning
most of this rain would rapidly run off.

* Runoff from excessive rainfall may cause rapid rises of water
in low-lying and poor drainage areas as well as streams and
creeks, resulting in flash flooding. Urban areas will be most
susceptible.

Precautionary/preparedness actions...

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.
