CONCORD, N.H. -- The death toll from a powerful winter storm that pushed through the U.S. midsection into the Northeast has risen to 12.

Officials in Indiana say a man and a woman were killed when the scooter they were riding went out of control on a snowy street Wednesday and they were hit by a pickup truck. Other deaths include a man checking on a disabled vehicle who was struck and killed in Pennsylvania and two people killed in crashes in Virginia.

The storm was dumping snow on parts of the Northeast a day after it caused more than 1,600 flight cancellations and frustrated holiday travellers.

Despite the weather, no flights were delayed Thursday morning cities like New York, Philadelphia and Boston. The coast was seeing mostly cold rain and high winds, not snow.

National Weather Service spokesman David Roth said the Northeast's heaviest snowfall would be in northern Pennsylvania, upstate New York and inland sections of several New England states before the storm ended Friday morning and headed to Canada.
