...FLOOD WATCH IN EFFECT FROM THURSDAY MORNING THROUGH FRIDAY
AFTERNOON...

The National Weather Service in Mount Holly has issued a

* Flood Watch for portions of central New Jersey, northern New 
  Jersey, and northwest New Jersey, including the following 
  areas, in central New Jersey, Mercer and Western Monmouth. In 
  northern New Jersey, Middlesex, Morris, Somerset, Sussex, and 
  Warren. In northwest New Jersey, Hunterdon. 

* From Thursday morning through Friday afternoon

* Rain is forecast to overspread central and northern New Jersey on 
  Thursday. The rain is expected to be moderate to heavy during 
  the late morning and afternoon.

* Rainfall totals of one to two inches with isolated three inch 
  amounts are expected. This will be the third rainfall event in the 
  last week. Like the first two, the rainfall could be heavy at 
  times and accumulations are forecast to be in excess on one inch. 
  The ground remains wet and rivers and streams continue to run high.

* The moderate to heavy rain will likely result in some roadway 
  flooding along with flooding in areas of poor drainage on 
  Thursday. Some small streams and creeks may leave their banks 
  Thursday afternoon into Thursday night. Minor to moderate flooding 
  could then occur along a number of larger rivers late Thursday 
  night into Friday. The river flooding could persist through the 
  weekend. 

* Please refer to AHPS for the latest. Confidence is higher that a
  number of forecast points will hit their Flood Stage. But with
  rainfall about 48 hours away, confidence is much less regarding
  any moderate flooding that is forecast.

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. If you live in an area prone to flooding, be 
prepared to take action should flooding develop.
