The National Weather Service has issued a coastal flood watch for residents living along the coast of Rhode Island and Massachusetts. According to the NWS, high tides and strong winds are expected to bring coastal flooding to the area over the next few days.
Residents are advised to take precautions and prepare for possible flooding. Those living in low-lying areas should consider moving to higher ground, and all residents should have an emergency kit on hand in case of power outages or other disruptions.
The NWS recommends that residents stay informed about the latest weather conditions by checking local news sources and following the NWS on social media. They also encourage residents to sign up for emergency alerts through their local government or the NWS’s Wireless Emergency Alerts system.
Coastal flooding can be dangerous, so it’s important for residents to take the necessary precautions and follow any evacuation orders that may be issued. The NWS will continue to monitor the situation and provide updates as needed.

…COASTAL FLOOD WATCH IN EFFECT FROM LATE THURSDAY NIGHT THROUGH
FRIDAY AFTERNOON…
* WHAT…One to two feet of inundation above ground level
possible in low-lying areas near shorelines and tidal
waterways (4.5 to 13.6 feet Mean Lower Low Water).
* WHERE…Portions of eastern, northeastern and southeastern
Massachusetts and northern and southern Rhode Island.
* WHEN…From late Thursday night through Friday afternoon.
* IMPACTS…Widespread minor coastal flooding is expected along
portions of both the east and south coasts during the Friday
morning high tide cycle with pockets of moderate coastal
flooding possible. The greatest concern for pockets of moderate
coastal flooding will be across north shore given their exposure
to an east southeast winds. Typically vulnerable shoreline
roads may become flooded and impassable within a few hours of
high tide. In addition…there may be significant beach erosion
on the south coast including ocean exposed beaches of Rhode
Island and Wesport. Significant beach erosion may also occur on
the south side of Marthas Vineyard and Nantucket.
* ADDITIONAL DETAILS…We also will have to watch the potential
for perhaps some additional coastal flooding near the south
coast with the Friday evening high tide. This remains more
uncertain and would become more problematic if the storm system
would slow down a few hours.
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.
