A long-duration ice storm impacting portions of the Southern Plains and mid-South is expected to last until Wednesday, bringing the potential for power outages, tree damage and dangerous road conditions to several states.
The big picture: About 3.3 million Americans were under an ice storm warning on Tuesday morning, with 16.5 million under a winter storm warning, according to the National Weather Service. Many more were under other types of winter weather alerts, such as wind chill advisories.
