...FLOOD WATCH IN EFFECT FROM LATE TONIGHT THROUGH MONDAY
EVENING...

The National Weather Service in Mount Holly has issued a

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

* From late tonight through Monday evening

* The remnant low of Gordon will pass to the north and west of 
  the region late this weekend and early in the new week. With 
  abundant moisture out ahead of it, a prolonged period of 
  moderate to heavy rain will fall starting late tonight and 
  continuing into Monday. 1 to 3 inches of rain is expected 
  throughout the watch area, but there is the potential for 
  training of thunderstorms that could result in 5 inches or more 
  of rain. The grounds in southeast Pennsylvania and most of New 
  Jersey are quite saturated, so it will not take much for 
  flooding to occur. 

* Excessive rainfall will lead to rapidly rising water and
  flooding, particularly in urban areas and along small creeks and
  streams. There is also the potential for flash flooding during
  this time. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.

...FLOOD WATCH REMAINS IN EFFECT THROUGH LATE TONIGHT...

The Flood Watch continues for

* Portions of northern Delaware, northeast Maryland, New Jersey, 
  and Pennsylvania, including the following areas, in northern 
  Delaware, New Castle. In northeast Maryland, Cecil. In New 
  Jersey, Atlantic, Camden, Coastal Ocean, Cumberland, Eastern 
  Monmouth, Gloucester, Hunterdon, Mercer, Middlesex, Morris, 
  Northwestern Burlington, Ocean, Salem, Somerset, Southeastern 
  Burlington, Sussex, Warren, and Western Monmouth. In 
  Pennsylvania, Berks, Carbon, Delaware, Eastern Chester, 
  Eastern Montgomery, Lehigh, Lower Bucks, Monroe, Northampton, 
  Philadelphia, Upper Bucks, Western Chester, and Western 
  Montgomery. 

* Through late tonight

* Periods of rain should transition to showers today from south to
  north. While much of the rain intensity is light to moderate,
  the threat for heavier downpours will increase through tonight.
  With widespread 1 to 3 inch totals occurring across the area
  already, any heavier rainfall that occurs today will likely lead
  to instances of flooding. 

* Excessive rainfall and runoff can lead to rising water and
  flooding, particularly in urban areas and along small creeks and
  streams. There is the potential for localized flash flooding
  during times of high rainfall rates. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
Flood Warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
