An overhead sign warns that Interstate 70 is closed to the east as a tractor trailer heads out of Aurora, Colo., as a late winter storm packing wet, heavy snow and high winds swept over the intermountain West on Saturday, March 9, 2013.

A powerful storm dumped snow on the Rocky Mountains on Sunday, after having forced the cancellation of hundreds of flights and the postponement of a Major League Soccer game. 

The fierce Pacific storm was moving east across the Plains into the Midwest, and blizzard conditions were possible in parts of Nebraska and northwest Kansas, The Weather Channel reported.

Forecasters also said that parts of the region could expect wind gusts of up to 50-miles-an-hour and white out conditions.

Meteorologists said there could be accumulations of 3 to 6 inches in portions of Iowa, Minnesota, central Wisconsin and northern Michigan as well on Sunday.

Snow pounded Denver, Colo., Saturday, falling at more than an inch per hour at times. Nearly 500 flights out of Denver International Airport had to be canceled. The Weather Channel's Mike Seidel reports.

The late-winter blast has already dumped up to 10 inches of heavy, wet snow in the Denver metropolitan area, The Weather Channel reported.

More than 600 flights in and out of Denver International Airport were canceled on Saturday, according to the Associated Press.

"Many of the canceled flights are commuter flights that go to mountain towns," airport spokesman Heath Montgomery told Reuters, adding that the facility remained open.
