A coastal flood warning is in effect for several Massachusetts counties, including Nantucket, beginning Monday at 1 a.m. And lasting until 7 a.m., according to the National Weather Service. The warning, issued Saturday afternoon, anticipates inundation levels of two to three feet above ground in low-lying coastal areas and along tidal waterways.
The weather service specifically highlighted potential impacts to Nantucket Harbor, where roads including Uncomplicated Street, South Beach Street, Easton Street, Walsh Street, Willard Street, and Straight Wharf are expected to turn into impassable with one to two feet of water, potentially disrupting access to ferry terminals. Flooding of one to three feet is also anticipated on coastal roads, including the Chappy Ferry Dock and Dock Street near Edgartown Harbor. In Vineyard Haven, Five Corners, Beach Road, and Water Street are predicted to be affected. East Chop Drive, a section of Lake Avenue near Oak Bluffs Harbor, and Sea View Avenue in Oak Bluffs are also at risk, with the possibility of debris washing onto roadways.
Authorities advise residents to take necessary precautions to protect flood-prone property and to avoid driving through barricades or areas where water depth is unknown. The National Weather Service cautions that even 12 inches of fast-flowing water can sweep most vehicles away.
The warning follows the release of an updated winter storm watch for Nantucket County, valid from Sunday 4 p.m. Through Tuesday 7 a.m. The watch anticipates heavy snow, potentially mixed with rain, and wind gusts up to 70 mph. The weather service warns that travel could be very difficult, impacting commutes, and that strong winds may cause tree damage.
A blizzard warning is also in effect for Plymouth, Massachusetts, from February 22, 4:00 PM EST until February 24, 07:00 AM EST. Current conditions at Plymouth Municipal Airport show light snow and a temperature of 30°F, with a wind chill of 20°F.
The National Weather Service emphasizes the importance of seeking higher ground if residing in a flood-prone area or camping in low-lying terrain. Evacuation orders should be followed promptly, and utilities and appliances disconnected if time allows. Individuals should avoid basements and areas with submerged electrical outlets, and evacuate immediately if sparks or buzzing sounds are detected.
