A massive winter storm is set to bring a mix of ice, snow, and frigid temperatures to nearly three-quarters of the US, affecting over 200 million people. The system, which has been dubbed one of the largest in five years, will slowly move eastward, bringing prolonged periods of snow and accumulating ice.
The National Weather Service has issued winter weather alerts for parts of the country, including the Southern Plains, the Mississippi and Tennessee Valleys, and the Northeast and Mid-Atlantic. A state of emergency has been declared in 17 states and Washington D.C., with nine states activating their National Guard troops.
Temperatures are expected to plummet to record lows across the South and Mid-Atlantic, with some areas seeing extreme cold temperatures. The polar vortex is also dipping down into the US, bringing unusually cold temperatures that could lead to frostbite in as little as 5-10 minutes.
The storm's track has been forecast to bring heavy snowfall amounts upwards of 12-18 inches from the Southern Plains up into the Northeast. However, the expected totals are still in flux for individual locations as forecast models continue to come together.
Travel will be disrupted by weather conditions on roadways and at airports, with some airlines issuing travel waivers and others adding extra flights to help accommodate the surge of travelers. The roads could become treacherous and hazardous, with officials urging drivers to exercise caution.
Preparations are underway across the country, including utility workers being pre-positioned in key areas, and cities such as New York City deploying large quantities of salt to keep streets and highways clear. In Texas, officials are working overtime to prepare for widespread power outages, having learned from a similar ice storm in 2021 that killed over 200 people.
Despite the uncertainty surrounding the forecast, weather prediction models are becoming more reliable as the storm's arrival nears. The main challenge is predicting the type of precipitation that will fall, with slight changes in temperature affecting the forecast dramatically.
