Flash Flood Watch in effect from midnight tonight through Tues morning. Be prepared to take action in the event that flooding develops.
The National Weather Service in Mount Holly has issued a
* Flash Flood Watch
* From midnight EDT tonight through Tuesday morning
* bands of heavy showers and thunderstorms may produce narrow
swaths of very heavy rainfall in a short period of time. This
could lead to excessive short term runoff and flash flooding.
Urban areas and those locations that had flooding last Friday
are more vulnerable to flooding.
* Heaviest rain and associated thunderstorms will most likely
occur between 3 am and 8 am Tuesday.
* There is uncertainty where the heaviest rain will occur later
tonight. For now it appears the region from Coatesville and
Philadelphia Pennsylvania, Wilmington and Dover Delaware
through Atlantic City and Cape May New Jersey will see
widespread 1 inch amounts with potential for 3 hour rainfall of
3 to 4 inches in a few locations.
* Impacts... Road closures due to localized excessive short term
rainfall are possible late tonight or early Tuesday morning as
well as a few instances of small stream flooding.
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.
Basement flooding is possible due to heavy rain falling on soils
already saturated from previous storms. If your home has a history
of basement flooding, monitor your sump pump for proper operation
and if possible, direct outside water flow away from your house
