OCEAN ISLE BEACH, N.C. (AP) – A winter storm that left millions without power in record-breaking cold weather has claimed more lives. The dead include three people found dead after a tornado (pictured) hit a seaside town in North Carolina and four family members who perished in a Houston-area house fire while using a fireplace to stay warm. The storm that overwhelmed power grids and immobilized the Southern Plains carried heavy snow and freezing rain into New England and the Deep South and left behind painfully low temperatures. Wind-chill warnings extended from Canada into Mexico. At least 11 deaths were reported from other causes, including car crashes and carbon monoxide poisoning.
