...FLOOD WATCH REMAINS IN EFFECT THROUGH SATURDAY AFTERNOON...

The Flood Watch continues for

* Delaware, northeast Maryland, most of New Jersey, and portions
  of southeast Pennsylvania.

* Through Saturday afternoon

* Periods of moderate to heavy rain will move into southern New
  Jersey and the Delmarva this morning. Periods of moderate to
  heavy rain will move into Delmarva late tonight through Saturday
  morning, then expand northward into southeastern Pennsylvania
  and New Jersey Saturday afternoon and night. Additional rainfall
  amounts of 1 to 4 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.
