New England and Canada

  • Timing: Snow ends in southeast New England Wednesday afternoon or early evening, and in eastern Maine Wednesday night.
  • Snow totals: Heaviest totals likely across Downeast Maine, Cape Cod, Martha's Vineyard and Nantucket with over 6 inches of snow. A few areas could see over a foot. Accumulations will drop off rapidly just to the west, with little or nothing across much of interior New England.
  • Wind impact: Winds slowly diminishing Wednesday afternoon over Cape Cod, Martha's Vineyard and Nantucket Island, but gusts continue to top 40 mph and in some cases 60 mph. (See below for wind reports already received.) Some gusts over 60 mph also possible in parts of Downeast Maine Wednesday and Wednesday evening. Expect power outages and tree limbs downed. A few gusts over 50 mph are possible as far west as Boston Wednesday.
  • Coastal flood threat: Coastal flooding into early Wednesday afternoon on the north side of Nantucket. Improving conditions by later Wednesday afternoon. Beach erosion is likely on ocean side of Cape Cod and east shore of Nantucket, according to the National Weather Service in Taunton, Mass.
  • Canadian impacts: A major blizzard is underway or imminent across portions of the Canadian provinces of Nova Scotia, New Brunswick, and Prince Edward Island, potentially expanding into Newfoundland later in the day. Depending on the storm track, some areas may change over to rain after a burst of heavy snow. Wind gusts of 60 to 70 mph will occur in many areas, and some locations have already reported gusts of 80 to 100 mph. Sustained winds of 50 to 65 mph are being reported in some coastal communities of Nova Scotia.
  • Offshore, marine impacts: The National Weather Service has issued hurricane force wind warnings for the ocean waters off the New England coast, including the waters immediately east of Cape Cod and along the south shores of Nantucket and Martha's Vineyard, as well as the nearshore waters just off Downeast Maine. Well offshore, sustained winds could reach 105 mph and seas could reach 40 to 50 feet with some individual waves even higher than that. Gusts over 75 mph are possible just off Outer Cape Cod and just off Martha's Vineyard and Nantucket along with dangerous seas. Gusts as high as 119 mph have been reported in the Gulf of Maine. All vessels are advised to stay in port while the storm passes by.
