...FLOOD WATCH NOW IN EFFECT FROM 6 PM EDT THIS EVENING THROUGH
SATURDAY AFTERNOON...

The Flood Watch is now in effect for

* Portions of Delaware, northeast Maryland, New Jersey, and
  Pennsylvania, including the following areas, in Delaware,
  Delaware Beaches, Inland Sussex, Kent, and New Castle. In
  northeast Maryland, Caroline, Cecil, Kent MD, Queen Annes, and
  Talbot. In New Jersey, Atlantic, Atlantic Coastal Cape May,
  Camden, Cape May, Coastal Atlantic, Coastal Ocean, Cumberland,
  Eastern Monmouth, Gloucester, Hunterdon, Mercer, Middlesex,
  Northwestern Burlington, Ocean, Salem, 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.

* From 6 PM EDT this evening through Saturday afternoon.

* Periods of light to moderate rain will continue this evening,
  and then heavy rain will move into Delmarva tonight. Periods of
  moderate to heavy rain will persist into Saturday. Additional
  rainfall amounts of 1 to 5 inches are expected over the next 72
  hours with the highest totals occurring in Delmarva and far
  southern New Jersey. Locally higher amounts over 5 inches are
  possible in slow- moving thunderstorms.

* A variety of flooding types are possible. Low-lying and poor
  drainage flooding will be the most common type of flooding to
  develop. Flash flooding will also be possible if thunderstorms
  repeatedly move over the same locations, especially in urban
  areas where rainfall runoff is maximized and where small
  creeks and streams respond quickly. Flash flooding occurs
  quicker than other types flooding due to the torrential rain
  thunderstorms can produce in a short amount of time. Several
  days of excessive runoff will eventually lead to a risk of
  flooding in larger streams and rivers though the extent of the
  flooding will depend on where the heaviest rain falls.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

If you live across the Passaic, Raritan, and Rancocas basins in
New Jersey or the Neshaminy, Schuylkill, and Brandywine basins
across Pennsylvania and Delaware, keep an eye on later river
forecasts. These forecasts, as well as all of our hydrologic
forecasts, can be accessed via our Advanced Hydrologic Prediction
Service website. Those living in areas prone to flooding should
be prepared to take action should flooding develop.
