BOSTON -- The National Weather Service issued a winter storm warning, which is in effect from Wednesday at 8 a.m. through 1 a.m. Thursday. Snow is expected to start between 7 a.m. and 10 a.m., becoming heavy at times during the afternoon and continuing into the evening.

Forecasters said snowfall rates of 1 to 2 inches per hour are likely in the early afternoon, resulting in tricky driving conditions.

StormTeam 5 meteorologist J.C. Monahan said the storm will begin to arc north toward the New England coastline on Wednesday, the bulk of the storm arriving by midday. Once it reaches Massachusetts it will continue to snow all day and will begin to accumulate in the late afternoon and evening.

A general snowfall of 6 to 10 inches was forecast for areas south of a line from Cape Ann to Worcester. North of that line, 4 to 8 inches were forecast. On the South Shore down through the South Coast, 8 to 12 inches were forecast. Southern New Hampshire was predicted to get 3 to 5 inches.

Strong winds on Cape Cod could result in blowing and drifting snow and there is the potential for power outages. There will be high north to northeasterly winds on the Cape, gusting up to 60 mph.

"The key to all this is that people cooperate -- people should take public transportation. Don't drive into the city tomorrow," said Boston Mayor Tom Menino.

Residents with storm-related questions or concerns should call the mayor's 24-Hour Hotline at 617-635-4500. In the event that school is canceled, community centers will open at 7:30 a.m. to accommodate any kids that need a place to stay.
