* showers and thunderstorms with heavy rain will develop starting
Friday afternoon and will first move into northeast Maryland,
Delaware, southeast Pennsylvania, and southern New Jersey,
before lifting north towards central New Jersey. Additional
waves of showers and thunderstorms with heavy rain will then
continue to impact these same areas Friday night through
Saturday afternoon. Rainfall amounts during this time will
generally range from 2 to 4 inches, but training of
thunderstorms may result in significantly higher amounts.

* Heavy rain falling in a short period of time will result in
rapidly rising water levels along streams and creeks and in
areas of poor drainage. Significant roadway flooding may occur.
It is also important to note that heavy rain will fall over
areas that already received several inches of rain early this
week, so it will not take much for flooding to occur.

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.
