Coastal Flood Advisory issued February 1 at 1:52AM EST until February 2 at 2:00PM EST by NWS Boston/Norton MA

Effective: Sun February 1, 2026, 1:52 AM
Expires: Sun February 1, 2026, 6:00 PM

* WHAT...One to two feet of inundation above ground level expected in low-lying areas near shorelines and tidal waterways (10.8 to 12.7 feet Mean Lower Low Water). * WHERE...Eastern Essex MA, Suffolk MA, Eastern Norfolk MA, Eastern Plymouth MA, Barnstable MA and Dukes MA Counties. * WHEN...From 8 AM this morning to 2 PM EST Monday. * IMPACTS...Shallow pockets of flooding less than one foot deep affects the lowest lying areas along the coast, including Morrissey Boulevard in Boston. Most roads remain passable. Flooding up to one foot deep affects coastal roads on the North Shore from Salem to Gloucester and Newburyport. Rough surf will cause flooding on some coastal roads around the time of high tide due to splashover. Roads remain passable with pockets of shallow flooding less than one foot deep. This mainly affects low lying areas and roads near Edgartown Harbor, including the Chappy Ferry Dock. Shallow flooding may also approach Five Corners in Vineyard Haven. * ADDITIONAL DETAILS...Sub-freezing temperatures and cold road surfaces may allow for some of the storm surge to freeze. This would result in prolonged issues on those vulnerable roadways and also delay drainage.

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.

* 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 MA coastline. * WHEN...Until 2 PM EST Monday. * IMPACTS...Shallow pockets of flooding less than one foot deep affects the lowest lying areas along the coast, including Morrissey Boulevard in Boston. Most roads remain passable. Flooding up to one foot deep affects coastal roads on the North Shore from Salem to Gloucester and Newburyport. Rough surf will cause flooding on some coastal roads around the time of high tide due to splashover. Roads remain passable with pockets of shallow flooding less than one foot deep. This mainly affects low lying areas and roads near Edgartown Harbor, including the Chappy Ferry Dock. Shallow flooding may also approach Five Corners in Vineyard Haven. * ADDITIONAL DETAILS...Two additional high tide cycles will result in pockets of minor coastal flooding. The first is very late tonight with the second around lunchtime Monday. Sub-freezing temperatures and very cold road surfaces could allow storm surge to freeze, prolonging impacts and delaying drainage after high tide periods.

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.
