OKLAHOMA CITY (AP) -- The death toll has risen to six from winter storms in the nation's midsection.
Two people in a car on a sleet-slickened Arkansas highway died Wednesday when the vehicle crossed the center line and struck an SUV head-on.
In Oklahoma, the Highway Patrol said a 76-year-old Wisconsin woman died Tuesday. She was a passenger in a car that was hit head-on when a pickup truck crossed into oncoming traffic on Interstate 44.
The Highway Patrol had earlier reported that a 28-year-old woman was killed in a crash on a snowy highway near Fairview, Okla.
The storm's winds were also blamed Tuesday for toppling a tree onto a pickup truck in Texas, killing the driver, and another tree onto a house in Louisiana, killing a man there.
Meantime, post-Christmas travelers braced for a second day of flight delays and cancellations after the rare Christmas Day twisters splintered numerous homes. They were facing treacherous driving conditions from freezing rain and blizzard conditions.
Farther north on a line from Little Rock, Ark., to Cleveland, blizzard conditions are predicted for snow up to a foot deep as the system churned toward the Northeast.
Mobile was the biggest city hit by a twister on Tuesday. The storms knocked down countless trees, blew the roofs off homes and left many Christmas celebrations in the dark.
Severe thunderstorms were forecast for the Carolinas while a line of blizzard and winter storm warnings stretched from Arkansas up the Ohio River to New York and on to Maine.
34 tornadoes were reported in Texas, Louisiana, Mississippi and Alabama during the outbreak Tuesday, the National Weather Service said.
