WASHINGTON, Feb. 5 (Xinhua) -- Two dozen states in northeast and central U.S. have been hit by a powerful winter snowstorm, the second of its kind that covered the same region last month.
The winter snowstorm brought overnight with extremely low temperature, accompanied with an onslaught of snow and ice since the late hours Tuesday evening.
In some areas ravaged by the snowstorm, visibility was near zero, and every snowplow has been working around the clock, local media reported.
More than 115 million people in 32 states were in the path of the storm that threatened to cut power, ground flights and snarl traffic. Governors in states from Arkansas to New Jersey declared emergencies.
The U.S. National Weather Service also issued winter storm warnings across 15 states early Tuesday from the Rockies to southern Maine.
A meteorologist with the Weather Service said a long arm of the northeast could be pounded by more than 12 inches of snow.
Until Thursday morning, when freezing rain and sleet join the snowfall, traffic in the snowstorm-hit areas will be very tough, he added.
Major cities like New York, Philadelphia and Washington will likely avoid the worst, but local authorities cautioned residents to brace for bone-chilling rain and ice.
Meanwhile, the National Weather Service issued a winter storm warning for New York City beginning overnight and running until 6 p.m. Wednesday. The city authorities also issued travel advisory for people walking in street during the day.
Influenced by the snowstorm, more than 2,000 flights into or out of U.S. airports have been canceled so far.
