BOSTON -- An ocean storm backing into New England planned to stick around through Sunday, bringing bursts of heavy snow, high winds and flooding along the coast.

Light snow falling across much of the region and was expected to continue. The winds strengthened, gusting up to 50 mph, and driving conditions deteriorated because of blowing and drifting snow, StormTeam 5’s Mike Wankum said. A wind advisory will be in effect from 7 p.m. Saturday until 4 p.m. Sunday.

Because of the long duration of the storm, snowfall totals will add up with 3 to 7 inches forecast from Worcester and west and 5 to 10 inches in the greater Boston metropolitan area, South Shore and the Cape. Cape Ann and northward areas could get as much as 6 inches to a foot. Parts of Maine could get as much as 2 feet of snow.

Coastal areas were seeing higher tides than normal, and many roads along the South Shore were flooded by deep pools of storm water on Saturday. In Dorchester, portions of Morrissey Boulevard were blocked off for hours as flood waters spilled onto the roadway.

A coastal flood watch will be in effect again Sunday, with another astronomically high tide coming just before 1 p.m. The storm could produce a surge of 1 to 2 feet with waves of 5 to 8 feet. Minor coastal flooding and minor beach erosion is expected

By Sunday night, when the worst is expected to be over, the White and Green Mountains could see up to 18 inches of snow. Portland was forecast for anywhere from 8 to 15 inches, and Concord, N.H., could get 6 inches to a foot.

The storm is expected to leave the Northeast on Monday, with a few lingering snow showers in the mountains throughout most of the week and seasonable temperatures.
