NORMAN, Okla. (AP) - Officials are warning people to stay off the roads as a blizzard brings more than a foot of snow and white-out conditions to parts of western and northern Oklahoma.

A blizzard warning is in effect until 6 a.m. Tuesday for the Oklahoma Panhandle and counties along the Kansas border. The National Weather Service warns that travel will be "very dangerous" until Tuesday morning, with visibility near zero and drifting snow.

Forecasters say travel will be especially treacherous near Interstate 40.

Forecasters expect 8 to 12 inches of snow, with up to 16 inches possible in some local areas. Winds of 30 to 40 mph are predicted, and forecasters say gusts of up to 55 mph are possible.
