    Flood Watch - 1:57am Sun Sep 13 2026

    ...FLOOD WATCH REMAINS IN EFFECT FROM 5 AM EDT EARLY THIS MORNING THROUGH THIS AFTERNOON...

    WHAT: Flooding caused by excessive rainfall continues to be
    possible.

    WHERE: Portions of eastern Connecticut and south central
    Massachusetts.

    WHEN: From 5 AM EDT early this morning through this 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 overspread the region this morning.
    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.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

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