• Timing: Snow moves into southern New England Tuesday night and intensifies in parts of eastern New England Wednesday. 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: Gusts over 60 mph likely over Cape Cod, Martha's Vineyard and Nantucket Island Wednesday morning, tapering off during the afternoon. 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: Minor to moderate coastal flooding for Wednesday morning high tide along north-facing shorelines of Cape Cod and Nantucket. 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: Regardless of the exact track, a major blizzard appears likely 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 are likely in many areas.
• 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. Well offshore, sustained winds could reach 90 to 95 mph and seas could reach 50 feet with some individual waves even higher than that. Hurricane-force gusts are possible just off Outer Cape Cod and just off Martha's Vineyard and Nantucket along with dangerous seas. All vessels are advised to return to port and stay in port while the storm passes by.
