A developing ocean storm could bring four to eight inches of heavy snow and high winds, according to an updated National Weather Service advisory issued for the region Saturday evening. 

Snow was predicted to begin falling heavily after midnight and last until midday Sunday, resulting in near-blizzard conditions, poor visibility and potential power outages, the advisory said. Sustained winds of 35 to 45 miles per hour, with gusts up to 55 miles per hour, are expected to buffet the Island.

High wind gusts may affect ferry travel on Sunday and Monday, Dukes County Emergency Management director Chuck Cotnoir said in a statement issued Saturday. “Forecasts can change as the storm track is uncertain at this time," said Mr. Cotnoir.

The storm comes just one week after a blizzard battered the Vineyard, delivering damaging winds up to 85 miles per hour and up to 14 inches of snow in some areas of the Island.
