A line of strong thunderstorms producing intense rainfall rates
will likely remain nearly stationary along the Interstate 95
corridor overnight. In additional... individual storms along this
line are likely to move repeatedly over the same area. This will
likely result in flash flooding... especially in urbanized areas.
Given high moisture content present over the area... intense
rainfall rates of two inches per hour are possible. Rainfall
totals of two to four inches of rain with isolated amounts of five
to six inches are possible overnight.

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.
