BOSTON (AP) – A storm that forecasters warned could be a blizzard for the history books began clobbering the New York-to-Boston corridor on Friday, grounding flights, closing workplaces and sending people rushing to get home ahead of a possible 1 to 3 feet of snow.

From New Jersey to Maine, shoppers crowded into supermarkets and hardware stores to buy food, snow shovels, flashlights and generators, something that became a precious commodity after Superstorm Sandy in October. Others gassed up their cars, another lesson learned all too well after Sandy. Across much of New England, schools closed well ahead of the first snowflakes.

“This is a storm of major proportions,” Boston Mayor Thomas Menino said. “Stay off the roads. Stay home.”
