    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.


    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.
