Storm Continues on a Path of Destruction Robert Ray/Associated Press An ambulance was stuck in more than a foot of snow off of Highway 33 West, near Belington, W.Va., on Tuesday. SCRANTON, Pa. - Flooded highways, downed power lines and rising rivers greeted people on Tuesday morning from Tennessee to Maine, with a blizzard warning and as much as three feet of snow expected to fall in West Virginia after the remnants of Hurricane Sandy rumbled through and a cold front from the north continued to push east. The storm, though vastly weaker than it was when it made landfall in New Jersey on Monday night, is moving west through southern Pennsylvania, bringing rain and high winds all the way to the Great Lakes, the National Weather Service reported. The system continued to pack winds of 65 miles per hour. Bowdon, W.Va., in the Appalachian Mountains, had received 14 inches of snow by Tuesday morning, and Mount Davis, in southern Pennsylvania, had 9 inches, the Weather Service said. A blizzard warning was in effect for the mountains of West Virginia and southwestern Virginia, where more than three feet of snow could eventually fall during the next few days, forecasters said. In Milford, Del., it was rain, not snow, causing trouble. Areas of central Delaware had received more than nine-and-a-half inches of rain by Tuesday morning, and a flood warning was in place along the Nanticoke River. Brian McNoldy, a hurricane expert at the University of Miami, said in an online posting Tuesday that heavy rainfall from the storm had also caused the Potomac River to reach its highest level since 1996. Flooding was expected along the river in Maryland and Virginia, officials said. Forecasters said on Tuesday that they no longer expected the storm to turn to the northeast and travel across New England. Instead, the track has shifted well to the west, and prediction models suggest it will move through central Pennsylvania and western New York State before entering southern Ontario by Wednesday, said Eric Blake, a hurricane specialist with the National Hurricane Center in Miami. As the storm continues to move inland and loses contact with the ocean - its source of moisture - rain levels are expected to diminish, though wind damage is still likely across a large area of the country, Mr. Blake said. "You've got rain or snow extending from Georgia through Maine and Michigan," he said. When you have something over Pennsylvania, and Lake Michigan is seeing gale-force winds, you've got a very large storm. Classes at public schools and universities had been canceled Tuesday as far north as Maine and Vermont, which is still coping from damage to roads and bridges from Hurricane Irene last year. In New Hampshire, more than 200,000 homes had no power, and in Maine, where more than 100,000 people were without electricity, a flood warning was issued for the Swift River. Most flights out of Portland International Jetport had been canceled Tuesday morning. Elsewhere in New England, there was heavy coastal flooding in Rhode Island and Massachusetts, where nearly 300,00 people had lost power. In Pennsylvania, where the storm continued to cause damage Tuesday and two people had died, Gov. Tom Corbett extended the deadline for voters to request absentee ballots from Tuesday to Thursday. But a deadline to return such ballots via the mail had not been extended beyond Friday, despite disruptions in mail service, according to the governor's office. One million people in the state had no electricity - and in northeastern Pennsylvania, near the town of Hazelton, officials have asked residents living near Nescopeck Creek to evacuate. Farther south, in North Carolina, Gov. Bev Perdue had declared one of the region's numerous state of emergencies for several counties in the western part of the state due to heavy snowfall caused by moisture swept in by Hurricane Sandy. The mountains of North Carolina and Tennessee are likely to get hit by more than 18 inches of snow over the next several days, while southwestern Virginia and parts of Kentucky may get even more - up to two feet, according to the National Weather Service. "Our average snowfall for the month of October is two inches, and now here we are at over 22 inches, and we still have another day to go," said Dana Soehn, a spokeswoman at Great Smoky Mountains National Park, which straddles the border between Tennessee and North Carolina. Those at lower elevations in the area were stuck with rain. "It's not pretty," said Jim Rigsby, who was working the reservation desk at the Music Road Inn in Pigeon Forge, Tenn. It's just rain and yuck. Winds from the storm continued to be felt as far away as eastern Alabama, with some gusts topping 35 miles per hour. In Maryland, at least two people were killed in weather-related accidents, one in a car accident, the second after a tree fell on a house, officials said. The Maryland Emergency Management Agency said more than 365,000 homes and businesses had lost power, including 80 percent of customers in the western part of the state.
