Coastal Flood Watch issued September 23 at 3:09PM EDT until September 26 at 5:00PM EDT by NWS Boston/Norton MA
Event:
Coastal Flood Watch
Urgency:
Future
Effective:
September 23, 2026 - 12:09pm
Expires:
September 24, 2026 - 1:30am
Description:
* WHAT...Up to one foot of inundation above ground level
possible in low-lying areas near shorelines and tidal
waterways (3.7 to 12.9 feet Mean Lower Low Water).
* WHERE...Eastern Essex, Suffolk, Eastern Norfolk, Eastern
Plymouth, Barnstable, Dukes and Nantucket Counties.
* WHEN...From Friday afternoon through Saturday afternoon.
* IMPACTS...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...The exact timing for an approaching
coastal low pressure remains uncertain. That will become
important for peak surge around the times of high tides.
Multiple tide cycles will be impacted, which combined with
strong onshore flow may result in tides not lowering as well.
Beach erosion will also be a concern, mainly for east-facing
beaches.
Instruction:
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.
