    ...STORM WARNING REMAINS IN EFFECT UNTIL 8 PM EDT SATURDAY...

    WHAT: Northeast winds 25 to 35 kt with gusts up to 55 kt and
    seas 6 to 9 feet.

    WHERE: Nantucket Sound, Vineyard Sound and Buzzards Bay.

    WHEN: Until 8 PM EDT Saturday.

    IMPACTS: Storm force winds and hazardous seas will capsize or
    damage vessels and reduce visibility.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Mariners should remain in port, alter course, and/or secure the
    vessel for severe conditions.

    Coastal Flood Warning - 12:35pm Fri Sep 25 2026

    ...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT SUNDAY... ...COASTAL FLOOD WARNING REMAINS IN EFFECT FROM 5 PM THIS AFTERNOON TO 8 PM EDT SUNDAY...

    WHAT: For the High Surf Advisory, large breaking waves of 6
    to 13 feet in the surf zone. For the Coastal Flood Warning, up
    to one foot of inundation above ground level expected in low-
    lying areas near shorelines and tidal waterways (4.0 to 12.6
    feet Mean Lower Low Water).

    WHERE: Eastern Essex MA, Suffolk MA, Eastern Norfolk MA,
    Eastern Plymouth MA, Barnstable MA, Dukes MA and Nantucket MA
    Counties.

    WHEN: For the High Surf Advisory, until 8 PM EDT Sunday. For
    the Coastal Flood Warning, from 5 PM this afternoon to 8 PM
    EDT Sunday.

    IMPACTS: Strong northeast winds with large waves will result in
    minor coastal flooding with pockets of moderate coastal flooding
    over multiple high tide cycles from late today through the
    weekend. The water also may struggle to vacate the area after
    the high tides given persistent strong northeast winds. The
    greatest risk for coastal flooding appears to be setting up
    south of Boston and onto the Cape and Islands. In addition...the
    long duration of northeast winds coupled with large waves over
    multiple high tide cycles will result in areas of severe beach
    erosion for a prolonged period.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Take the necessary actions to protect flood-prone property. If
    travel is required, do not drive around barricades or through
    water of unknown depth.

    Inexperienced swimmers should remain out of the water due to
    dangerous surf conditions.

    High Wind Warning - 12:30pm Fri Sep 25 2026

    ...HIGH WIND WARNING NOW IN EFFECT UNTIL 8 AM EDT SUNDAY...

    WHAT: Northeast winds 20 to 30 mph with gusts of 50 to 60 mph.

    WHERE: The eastern Massachusetts coast as well as the south coasts
    of both Rhode Island and Massachusetts. This includes Cape Cod and
    the Islands.

    WHEN: Until 8 AM EDT Sunday.

    IMPACTS: Damaging winds will blow down trees and power lines.
    Power outages are expected. Travel will be difficult, especially
    for high profile vehicles.

    ADDITIONAL DETAILS: The long duration of the winds coupled with
    heavy rain and fully leafed trees may exacerbate the risk for tree
    damage and power outages.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    People are urged to secure loose objects that could be blown around
    or damaged by the wind.

    High Surf Advisory - 12:35pm Fri Sep 25 2026

    ...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 8 PM EDT SUNDAY... ...COASTAL FLOOD WARNING REMAINS IN EFFECT FROM 5 PM THIS AFTERNOON TO 8 PM EDT SUNDAY...

    WHAT: For the High Surf Advisory, large breaking waves of 6
    to 13 feet in the surf zone. For the Coastal Flood Warning, up
    to one foot of inundation above ground level expected in low-
    lying areas near shorelines and tidal waterways (4.0 to 12.6
    feet Mean Lower Low Water).

    WHERE: Eastern Essex MA, Suffolk MA, Eastern Norfolk MA,
    Eastern Plymouth MA, Barnstable MA, Dukes MA and Nantucket MA
    Counties.

    WHEN: For the High Surf Advisory, until 8 PM EDT Sunday. For
    the Coastal Flood Warning, from 5 PM this afternoon to 8 PM
    EDT Sunday.

    IMPACTS: Strong northeast winds with large waves will result in
    minor coastal flooding with pockets of moderate coastal flooding
    over multiple high tide cycles from late today through the
    weekend. The water also may struggle to vacate the area after
    the high tides given persistent strong northeast winds. The
    greatest risk for coastal flooding appears to be setting up
    south of Boston and onto the Cape and Islands. In addition...the
    long duration of northeast winds coupled with large waves over
    multiple high tide cycles will result in areas of severe beach
    erosion for a prolonged period.

    PRECAUTIONARY / PREPAREDNESS ACTIONS:

    Take the necessary actions to protect flood-prone property. If
    travel is required, do not drive around barricades or through
    water of unknown depth.

    Inexperienced swimmers should remain out of the water due to
    dangerous surf conditions.

    Time of high total tides are approximate to the nearest hour.
