NATIONAL NEWS (CNN) — Superstorm Sandy has spent much of its fury crashing into homes and trees, and two days after downing power and wrecking cities on the East Coast, the storm's winds have slowed but are still delivering gale force gusts.
The center of the broad swath, with a size that has been compared to that of a large nation, was 50 miles east-northeast of Pittsburgh at 11 p.m. Eastern time, according to the National Weather Service. It continues moving towards Canada.
Its system still reaches from the Appalachians to the Great Lakes and beyond to Canada, and it is triggering winter storm warnings from the mountains of Pennsylvania to those of Eastern Tennessee and North Carolina.
Mountain regions in Maryland and West Virginia should see additional snow accumulations of 5 to 10 inches making for total of 1 to 3 feet dropped by the superstorm.
Farther north, the National Weather Service warns of the possibility of continued flooding due to rainfall, and high southerly winds could blow a small storm surge into the upper shores of the eastern Great Lakes.
High tides along the coast will come in on top of what is left of Sandy's storm surge, possibly causing some flooding.
A running CNN tally reflects a steady restoration of power to affected areas, but early Wednesday, nearly 6.3 million customers were still without power in 15 states and Washington.
