Active Weather Alerts
Coastal Flood Advisory
Issued: 4:48 AM Feb. 2, 2026 – National Weather Service
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 2 PM EST MONDAY... * 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. PRECAUTIONARY/PREPAREDNESS ACTIONS... 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. && && Time of high total tides are approximate to the nearest hour.
