rapidly increase over the area Wednesday night resulting in
significant moisture transport into the area. Periods of heavy
rainfall are anticipated late Wednesday night through Thursday
night across the central mid-Atlantic. The period of greatest
rain rates is expected late Wednesday night through Thursday
afternoon. Widespread rainfall amounts of 3 to 5 inches are
expected with localized higher totals in areas of repeated
activity. Additionally... eastern slopes of mountains such as
the northern Blue Ridge and Catoctin Mountain also have an
increased risk for higher rain totals.

* Potential exists for flash flooding of small streams... creeks
and urban areas especially in areas of repeated activity.

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.
