For the Freezing Spray Advisory, from 10 PM this evening to 10 AM EST Monday. * IMPACTS...Operating a vessel in freezing spray is hazardous. Freezing spray may render mechanical and electronic components inoperative. Ice accretion on decks and superstructures may result in some loss of stability. Strong winds will cause hazardous seas which could capsize or damage vessels and reduce visibility. PRECAUTIONARY/PREPAREDNESS ACTIONS... Mariners should prepare for ice accumulation on their vessel and consider altering plans to avoid or mitigate these hazardous conditions. During freezing spray conditions, the U.S. Coast Guard advises mariners to check and ensure all life-saving devices remain free of ice. Mariners should alter plans to avoid these hazardous conditions. Remain in port, seek safe harbor, alter course, and/or secure the vessel for hazardous conditions. &&

Coastal Flood Advisory
Issued: 6:02 PM Jan. 31, 2026 – National Weather Service
...COASTAL FLOOD ADVISORY IN EFFECT FROM 8 AM SUNDAY TO 2 PM EST MONDAY... * WHAT...One to two feet of inundation above ground level expected in low-lying areas near shorelines and tidal waterways (4.2 to 13.4 feet Mean Lower Low Water). * WHERE...Barnstable MA and Dukes MA Counties. * WHEN...Multiple high tide cycles Sunday morning into Monday afternoon. * IMPACTS...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. 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. && && Time of high total tides are approximate to the nearest hour.
