A winter storm that brought a mixture of rain and heavy snow to parts of Tennessee and New England this week is now predicted to cause dangerous travel conditions and disruptions throughout the East Coast.
The latest storm, which has already dumped nearly a foot of snow on East Coast residents, is on track to be the worst in years. The snow was expected to get heavier by afternoon and could complicate the evening rush hour, particularly in New England.
"We have two main pulses with this snowstorm," said expert Senior Meteorologist Alex Sosnowski. "The first pulse of locally heavy snow moved through the Philadelphia and New York City areas during the morning and midday hours. The second part of the storm,which may be more disruptive than the first, is expected to hit West Virginia."
The stormy weather led to airport delays and cancellations Wednesday. In Philadelphia, about 40 departing flights were canceled. Arriving flights are being delayed, with some for up to three hours.
There were also delays at Newark Liberty International Airport, and one hour delays on arrivals at LaGuardia Airport.
The National Weather Service said significant snowfall was forecast for the New York metropolitan area. Accumulations of up to 10 inches were forecast for the city, Rockland and Westchester counties and Long Island.
Philadelphia and New York City have declared a snow emergency.
Motorists will face difficult travel as the storm intensifies Wednesday evening. The storm is expected to pound the East Coast until Thursday morning.
