The Flash Flood Watch continues for

* Portions of Maryland, The District of Columbia, and Virginia,
including the following areas, in Maryland, Anne Arundel,
Calvert, Central and Southeast Howard, Central and Southeast
Montgomery, Charles, Northern Baltimore, Northwest Harford,
Northwest Howard, Northwest Montgomery, Prince Georges,

* Until 2 AM EDT Saturday

* Thunderstorms with heavy rainfall are expected across the region
through this 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.
