Major winter storm threatens much of the U.S. with intense cold, snow and ice
Tens of millions of Americans are bracing for a massive winter storm today, forecast to bring the heaviest snowfall and coldest temperatures in over a decade to parts of the country.
Kansas, Arkansas, Kentucky and Virginia have declared states of emergency as the storm, driven by a polar vortex, moved east after striking the central United States. Southern states like Mississippi and Florida also warned of dangerous cold and treacherous conditions, according to the National Weather Service.
A polar vortex is an area of low pressure and cold air that swirls like a wheel around each of Earth’s two polar regions. Sometimes, the Arctic polar vortex wobbles and a lobe surges south, blanketing parts of North America with bitter temperatures.
As the storm moved east, around 60 million people across 30 states from the Plains to the mid-Atlantic were under weather alerts, with a developing low-pressure system threatening heavy snow and crippling ice over the next three days.
