Dozens of deaths have been attributed to a series of winter storms that have pummeled the nation since Sunday, overwhelming power grids and immobilizing the Southern Plains.
The deaths include three people killed when a tornado struck coastal North Carolina around midnight Monday, destroying homes and injuring at least 10 other people.
Here are the latest updates:
The fatalities have been heavily concentrated in Texas, and especially Houston, where millions of residents were without power early this week as bitterly cold temperatures and dangerously icy conditions swept the region.
