OKLAHOMA CITY (NEWS1130) – The death toll has risen to six from winter storms in the US midsection that are pushing toward the Northeast.

Two passengers in a car on a sleet-slickened Arkansas highway died when their vehicle crossed the centre line and struck an SUV.

In Oklahoma, the Highway Patrol says a 76-year-old woman died when a truck crossed into oncoming traffic and hit the car she was in. The Highway Patrol earlier reported that a 28-year-old woman was killed in another crash.

The storm’s winds are also blamed for toppling a tree onto a truck in Texas, killing the driver, and a tree onto a house in Louisiana, killing a man.

More than 325 flights around the US were cancelled as of this morning, according to the flight tracker FlightAware.com. Most were at airports in the path of the storm.
