Emergency crews in Mississippi are working around the clock to clear icy highways as a severe winter storm has swept through the eastern U.S., causing delays and making roads impassable. Residents have been urged to remain indoors as temperatures plummet. An estimated 380,000 homes are still without power, while the death toll from the cold has mounted to at least 50. With forecasts predicting even colder weather and potentially more snowfall in the coming days, this weather pattern could mark one of the longest stretches of cold in decades.
