    Flood Warning - 1:20pm Mon Aug 3 2026

    ...FLOOD WARNING IN EFFECT UNTIL 315 PM EDT THIS AFTERNOON...

    WHAT: Urban area and small stream flooding caused by excessive
    rainfall is expected.

    WHERE: Portions of New Jersey, including the following counties,
    Burlington, Camden and Mercer and southeast Pennsylvania,
    including the following counties, Bucks, Delaware, Montgomery and
    Philadelphia.

    WHEN: Until 315 PM EDT.

    IMPACTS: It will take several hours for all the water from these
    storms to work through local drainage systems in urban areas.

    ADDITIONAL DETAILS: - At 112 PM EDT, reports of minor street flooding have occurred
    across the I95 urban corridor. The rainfall producing this
    street flooding is generally less than one half an inch but
    is resulting from several waves of rainfall that have
    occurred through the day today and no ability for the runoff
    to drain. The street flooding is not expected to be as life
    threatening as the flooding that occurred this morning but
    does pose a threat to property. Doppler radar indicated heavy
    rain. Quick minor street flooding will be either ongoing or
    could rise quickly as showers move through the warned area.
    Between 1 and 4 inches of rain have fallen across the storm
    total for today.
    - Additional rainfall amounts up to 1 inch are possible in the
    warned area.
    - Some locations that may experience flooding include...
    Philadelphia, Trenton, Camden, Bensalem, Ewing, Norristown,
    Yeadon, Burlington, Bristol, Conshohocken, Palmyra and
    Hatboro.

    ADDITIONAL DETAILS: - Multiple rounds of showers and thunderstorms will continue to
    impact the area through this evening with rainfall rates as
