New England residents have been warned to brace for yet another brutal winter storm, less than two weeks after a previous one downed trees and left hundreds of thousands without power. Winter weather advisories or warnings were in effect late Monday for much of the Northeast, including New York City, Boston, and Portland, Maine. Some areas in Massachusetts and Rhode Island were warned to expect up to 18 inches of snow, while Connecticut was on track to get between 8 and 12 inches. Forecasters said the storm could turn into a “bomb cyclone” with heavy snow and powerful winds. More than 1,000 flights scheduled for Tuesday have already been canceled in preparation for the storm, most of them in Boston.
