The Mississippi Highway Patrol is preparing for what it expects will be slick and dangerous road conditions Thursday.
Officials say there will likely be icy patches on the roads, and they could be especially bad on bridges and overpasses.
The MHP is advising residents to stay off the roads if at all possible.
"A bridge is the quickest thing to freeze because of the concrete on a bridge. So you're approaching a bridge and it's frozen, slow down," said SGT Malachi Sanders of MHP public affairs. "Slow down well in advance, before you get to that bridge. Also when you're approaching vehicles that are stopped in a lane of traffic or a stop sign, slow down. Come to almost a complete stop well in advance than you would ordinarily do."
Officials say road conditions could be bad for several days, as temperatures likely won't get above freezing.
