* Through this evening

* Periods of rain will continue across the region through this
afternoon, and possibly into this evening. Additional rain on an
already saturated ground will cause excessive runoff. Additional
rainfall amounts around one half to one inch are most likely
across the area, with the highest amounts east of the Blue Ridge
and Catoctin Mountains. While flash flooding cannot be ruled
out, the primary concern is flooding of small streams and low-
lying areas. Saturated ground may cause trees to become uprooted
and toppled.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
