    • Flash Flood Watch

      Flash Flood Watch in effect until Tuesday, 4:00 AM EDT. Source: U.S. National Weather Service


    The National Weather Service in Mount Holly has issued a

    * Flash Flood Watch for portions of Delaware, northeast
    Maryland, and Pennsylvania, including the following areas, in
    Delaware, Kent and New Castle. In northeast Maryland,
    Caroline, Cecil, Kent MD, Queen Annes, and Talbot. In
    Pennsylvania, Berks, Delaware, Eastern Chester, Eastern
    Montgomery, Lehigh, Lower Bucks, Philadelphia, Upper Bucks,
    Western Chester, and Western Montgomery.

    * Through late tonight

    * Showers and thunderstorms will overspread the area throughout
    the day and into this evening. Rainfall rates over 1 inch per
    hour will be possible, and training of heavy rain showers will
    also lead to areas of flash flooding.

    * Excessive rainfall within a short period of time can lead to
    rapidly rising water and flash flooding, particularly in urban
    areas and along small creeks and streams.


    A Flash Flood Watch means that there is the potential for flash
    flooding which can be life-threatening. Heavy rain is expected to
    occur over a short period of time. Rapidly rising flood waters may
    quickly inundate roadways and areas of poor drainage. Streams and
    creeks could leave their banks, flooding nearby properties.

    Please monitor the forecast, especially if you live in a location
    that is prone to flooding. Be prepared to take action if a flash
    flood warning is issued for your area.
