Coastal Flood Advisory issued February 1 at 11:48PM EST until February 2 at 2:00PM EST by NWS Boston/Norton MA

Effective: Sun February 1, 2026, 11:48 PM
Expires: Mon February 2, 2026, 2:00 PM

* WHAT...Up to one foot of inundation above ground level in low- lying areas near shorelines and tidal waterways (4.0 to 13.0 feet Mean Lower Low Water). * WHERE...The eastern Massachusetts coastline. * WHEN...Until 2 PM EST Monday. * IMPACTS...Roads remain passable. Shallow pockets of flooding less than one foot deep affect more vulnerable coastal roads along the North Shore from Salem and Gloucester to Newburyport. Rough surf will likely cause some splashover onto coastal roads around the time of high tide. Roads remain passable. Low lying areas and roads near Nantucket Harbor, including Easy Street, may experience pockets of shallow flooding less than one foot deep. * ADDITIONAL DETAILS...Sub-freezing temperatures and very cold road surfaces could allow storm surge to freeze, prolonging impacts and delaying drainage even after high tide.

If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.
