DENVER (AP) - A storm that has dumped more than a foot of snow in the Rocky Mountains is causing problems for travelers as it spreads across the Plains.
The main east-west route across Colorado, Interstate 70, was closed from east of Denver to the Kansas line because of poor visibility due to blowing snow Wednesday. Smaller highways were also closed in eastern Colorado.
Drivers in Iowa and Nebraska are being warned to be careful or stop driving altogether starting Wednesday evening as the Plains gets its first major winter storm of the season.
Light snow is also expected at Chicago's O'Hare International Airport Thursday and strong winds could make visibility poor. National Weather Service forecaster Jamie Enderlen says that, combined with low clouds, could cause delays at the nation's second-busiest airport.
