[Weather] [2025.08.22 PM] NWS Boston EM Briefing for Impacts of Erin

[BOX Operations - NOAA Service Account]

Good afternoon, all:

Here is our latest briefing regarding the impacts of Hurricane Erin:

Hurricane Erin has passed by our region earlier today but some fringe
effects will still be felt across coastal areas of southern New England:

High Surf and Rip Currents

   -

   High Surf Advisories are in effect into Saturday for most of the MA and
   RI coastline.
   -

   Focus is shifting from the beaches with south-facing exposures to those
   with an east-facing exposure tonight into Saturday.
   -

   Waves continue to diminish Sunday, but still expect at least a moderate
   risk for rip currents.
   -

   Water temperatures remain warm and some beachgoers may flock to the
   waters, which could put more people at risk.
   -

   Keep in mind that many beaches no longer have lifeguards for this season
   -

   Anyone going to view the surf should stay at a safe distance and off
   jetties or piers.
   -

   The risk for rip currents is expected to finally end for Monday.


Significant Beach Erosion

   -

   Swell from Erin should result in dune and beach erosion on east-facing
   shores this weekend.
   -

   Again the focus is shifting away from south-facing beaches.


Hazardous Marine Conditions on the Coastal Waters

   -

   Small Craft Advisories in effect for RI and MA coastal waters, except
   for Boston Harbor, Buzzards Bay and Narragansett Bay.
   -

   Winds are not much of a concern, it will take some time for rough seas
   to subside.


Minor Coastal Flooding

   -

   Coastal Flood Advisories are in effect for Martha’s Vineyard and
   Nantucket for the high tides late tonight, and for Narragansett Bay and
   south coastal MA/RI for the high tides this evening.
   -

   Minor coastal flooding is expected in vulnerable sections of Nantucket
   Harbor, Edgartown Harbor, Vineyard Haven, and Oak Bluffs this evening with
   a storm surge of 1 to 2 feet and waves up to 8 feet on Nantucket Sound.
   Low-end Moderate flooding is possible near Nantucket Harbor if we see a
   storm surge closer to 2 feet.
   -

   Minor coastal flooding is expected in low lying areas around
   Narragansett Bay and  the South Coast around high tide this evening with a
   storm surge of 1 to 2 feet.
   -

   No significant coastal flooding is expected along the E MA coast, but
   water levels could reach Action stage during high tides tonight.


This is expected to be our final briefing, unless there is a significant
change to the forecast.

Meteorologists Matthew Belk, Francis Tarasiewicz and Caity Mensch
