Millions endure record cold without power in US

The weather service's office in Wilmington, North Carolina, dispatched a team to confirm that a tornado did indeed touch down and to survey damage in Brunswick County, said Mark Willis, the office's meteorologist in charge.

Three people died and 10 were injured when the apparent tornado tore through a golf course community and another rural area just before midnight Monday, destroying dozens of homes.

Sharon Benson, 63, said her roof was damaged and her garage door blown off. Windows were shattered and nearby trees were uprooted.

"The sky lit up and there was a lot of pop-pop-popping" and thunder, she said.

Authorities in multiple states reported deaths in crashes on icy roads , including two people whose vehicle slid off a road and overturned in a waterway in Kentucky on Sunday, state police said.

In Texas, three young children and their grandmother died in the Houston-area fire, which likely began while they were using a fireplace to keep warm during a power outage, a fire official said.
