Christmas will be the coldest in decades due to a US winter storm.

Forecasters predict that this week's powerful winter storm may cause sections of the US to experience their coldest Christmas in four decades.
The "bomb cyclone" will develop into a "once-in-a-generation" cold spell by Friday after starting on Tuesday in the Pacific Northwest. Winter weather alerts are in effect for more than 90 million people in 37 states.
The majority of the country, up to and including Texas in the south, is expected to suffer below-freezing temperatures. According to estimates quoted by US media, the arctic blast, which the Weather Channel has named Winter Storm Elliot, is predicted to bring the Midwest its coldest Christmas since the late 1980s.
Even the Sunshine State of Florida is expected to see its coldest Christmas in thirty years. By the end of this week, certain sections of the country might experience bone-chilling temperatures between -50F (-45C) and -70F, according to the National Weather Service (NWS).
According to its warning, prolonged exposure to the cold could result in hypothermia and even death. "Wind chills of this magnitude can induce frostbite in less than five minutes if precautions are not followed," the alert stated.
As the storm approaches the Great Lakes region, where its pressure is anticipated to reach the equivalent of a Category 3 hurricane, the NWS has dubbed it a once-in-a-generation winter weather event.
State of emergencies have been proclaimed by the governors of North Carolina and Kentucky. This weekend, icy roads and snowfall are predicted to cause mayhem on the roads.
US Transportation Secretary Pete Buttigieg stated on Wednesday that there were few interruptions throughout the Thanksgiving holiday.
It won't be that way leading up to Christmas, regrettably.
Already canceled flights from Denver and Chicago number in the hundreds.On Thursday morning, Denver is expected to experience the worst of the cold snap as temperatures drop to -16F.
An indoor arena, the Denver Coliseum, is being transformed into a warming center.
Chicago has been forewarned that significant snowfall beginning on Thursday will be accompanied by wind gusts of up to 50 mph (80 km/h).
As the storm develops, meteorologists anticipate it will turn into a "bomb cyclone".
A storm is referred to as a bomb cyclone when it strengthens quickly and its central air pressure drops by at least 24 millibars in a 24-hour period.
As a result of the explosive power brought on by the sudden drop in pressure, they are also known as bomb cyclones.
Such storms provide a variety of weather, including blizzards, violent thunderstorms, and significant precipitation.
The east coasts of the US and Canada are where bomb cyclones most frequently occur because the region's chilly terrain and warm Gulf Stream current are ideal.
