...FLASH FLOOD WATCH IN EFFECT FROM 2 PM EDT THIS AFTERNOON
THROUGH THIS EVENING...
The National Weather Service in Mount Holly has issued a
* Flash Flood Watch for portions of southwestern, central and
northwestern New Jersey, eastern Pennsylvania, central and
southern Delaware and northeastern Maryland.
* From 2 PM EDT this afternoon through this evening
* Multiple rounds of showers and thunderstorms can be expected
through tonight. While flash flooding is not anticipated with
the initial round this morning, locally higher rainfall amounts
of 1 to 2 inches are possible, and will help saturate the ground
for the next round of storms. Torrential downpours with storms
that develop this afternoon and evening could produce rainfall
rates greater than 2 inches per hour. While the entire area will
not receive heavy rain, isolated rainfall totals of 3 to 6
inches are possible where storms track over the same locations.
* Torrential 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 is possible
in isolated areas.
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
