Snow and ice blanketed large swaths of the U.S. on Sunday, prompting canceled flights, making driving perilous and reaching into areas as far south as Texas Gulf Coast, where snow and sleet were expected overnight.
An unprecedented winter storm continued its assault on the nation Monday, killing at least four people, leaving millions without power in Texas and wreaking travel havoc across a wide swath of the U.S. because of heavy snow and ice.
At least three people were killed when a tornado hit Brunswick County, North Carolina, just after midnight Tuesday, also leaving at least 10 people injured, authorities said.
More than 150 million people were under a winter storm warning, winter weather advisory or ice storm warning in 25 states, stretching over 2,000 miles from southern Texas to northern Maine, the National Weather Service said.
The storm was forecast to continue to cover parts of the Midwest and Northeast with heavy snow into Tuesday morning before receding later in the day.
WINTER REACHES SOUTH: From Sunday night into Monday morning, rain will turn into sleet and snow in Houston. Dallas might get 6 inches of snow. Oklahoma National Guard troops are being called to help stranded drivers.
