    Flood Watch - 2:20am Sat Sep 12 2026

    ...FLOOD WATCH IN EFFECT FROM LATE TONIGHT THROUGH SUNDAY AFTERNOON...

    WHAT: Flooding caused by excessive rainfall is possible.

    WHERE: Rhode Island and southeast Massachusetts.

    WHEN: Very late tonight through Sunday afternoon.

    IMPACTS: Excessive runoff may result in flooding of low-lying and
    flood-prone locations. Flooding may occur in poor drainage and
    urban areas.

    ADDITIONAL DETAILS: - Showers and a few embedded thunderstorms with localized narrow
    bands of torrential rainfall are possible very late tonight into
    Sunday afternoon. Widespread rainfall amounts of 0.50 to 2 inches
    are expected. However...localized narrow bands of 2-4" of rain
    are possible within a 3 hour period. While it remains uncertain
    if these narrow bands of heavier rain occur...the potential
    exists for localized flash flooding...especially if it were to
    occur over a vulnerable urban center.

    Warnings. Those living in areas prone to flooding should be prepared
    to take action should flooding develop.
