Flood Watch

Flood Watch from Tomorrow at 7PM until 12/21 7PM. Be prepared to take action in the event that flooding develops.

* Flood Watch for portions of Delaware, much of New Jersey,
  southeast Pennsylvania along the tidal Delaware River, and
  northeast Maryland.

* From Thursday evening through Friday evening

* strong low pressure will impact the area Thursday night 
  through Friday, resulting in a widespread rainfall of 1.5 to 
  2.5 inches with locally higher amounts. 

* Given the recent heavy rain and how saturated he ground is, this
  amount of rain will result in flooding of roadways and areas of
  poor drainage, as well as the potential for significant river
  flooding. In addition to the freshwater flooding, the
  combination of heavy rain and increased tide levels during the
  times of high tide Thursday night through Friday morning will
  result in widespread moderate to locally major coastal flooding
  along the Atlantic, Delaware Bay, the tidal Delaware River, and
  the Eastern Shores of the Chesapeake Bay.

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.
