...FLASH FLOOD WATCH IN EFFECT UNTIL 10 AM EDT SUNDAY...

The National Weather Service in Mount Holly has issued a

* Flash Flood Watch for portions of New Jersey and Pennsylvania, 
  including the following areas, in New Jersey, Atlantic, 
  Camden, Coastal Atlantic, Coastal Ocean, Eastern Monmouth, 
  Gloucester, Hunterdon, Mercer, Middlesex, Morris, Northwestern 
  Burlington, Ocean, Somerset, Southeastern Burlington, Warren, 
  and Western Monmouth. In Pennsylvania, Berks, Delaware, 
  Eastern Chester, Eastern Montgomery, Lehigh, Lower Bucks, 
  Northampton, Philadelphia, Upper Bucks, Western Chester, and 
  Western Montgomery. 

* Until 10 AM EDT Sunday

* Showers and thunderstorms are expected to develop overnight in
  the general vicinity of the Interstate 78 corridor as a cold
  front sinks south into the area. These storms will be capable of
  producing very heavy rainfall with rainfall amounts in excess of
  2 to 3 inches possible in just a few hours. This may lead to
  urban and small stream flooding along with flooding of low-lying
  areas. Flash flooding will also be possible, especially if
  storms move repeatedly over the same areas. By morning, these
  showers and storms will shift southward along the front,
  affecting southeast Pennsylvania, including the Greater 
  Philadelphia area, and central New Jersey. Urban, small stream, 
  and flash flooding will remain a threat as the storms affect 
  these areas.
 
 PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that there is the potential for flash
flooding which can be life-threatening. Heavy rain is expected to
occur over a short period of time. Rapidly rising flood waters
may quickly inundate roadways and areas of poor drainage. Streams
and creeks could leave their banks, flooding nearby properties.

Please monitor the forecast, especially if you live in a location
that is prone to flooding. Be prepared to take action if a flash 
flood warning is issued for your area.
