    Weather Alerts
    Coastal Flood Advisory - 4:28am Wed Sep 23 2026

    ...COASTAL FLOOD ADVISORY NOW IN EFFECT FROM 4 PM THIS AFTERNOON TO 2 AM EDT SATURDAY...

    WHAT: Up to one foot of inundation above ground level
    expected in low-lying areas near shorelines and tidal
    waterways.

    WHERE: Middlesex and Western Monmouth.

    WHEN: From 4 PM this afternoon to 2 AM EDT Saturday.

    IMPACTS: At this level, flooding begins on the most
    vulnerable roads in coastal and bayside communities, and along
    inland tidal waterways. Some partial or full road closures are
    possible.

    ADDITIONAL DETAILS: Localized moderate tidal flooding impacts
    cannot be ruled out. Widespread minor tidal flooding could
    continue into the weekend.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    A Coastal Flood Advisory means that minor tidal flooding is
    expected. Minor tidal flooding often results in some road
    closures. Usually, the most vulnerable roadways will flood.

    Do not leave your vehicle at a location that is prone to tidal
    flooding. Do not drive your vehicle through flood waters. The
    water may be deeper than you think it is. You will be putting
    yourself in danger and your vehicle may be damaged, leading to
    costly repairs.

    Visit the National Water Prediction Service at
    https://water.noaa.gov/wfo/phi for additional water level and
    flood impact information for your local tide gauge.
