Officials in Mississippi say crews worked through the night to clear stranded vehicles on icy major highways as the eastern U.S. endures what could become its longest period of freezing cold in decades. Mississippi's Department of Transportation dispatched tow trucks and drones late Tuesday to frozen Interstate 55, where three tractor-trailers had stalled and caused a major backup. Gov. Tate Reeves said in social media post that highways remained dangerous Wednesday morning and urged people to stay off the roads. More than 380,000 people, mostly in Mississippi and Tennessee, remain without power days after a winter storm blasted the eastern U.S. with snow and ice. The East Coast could see more snowfall this weekend.
