Hundreds of flights have been canceled in Minnesota as heavy snow, strong winds, rain and hail from Gulf Coast to Great Lakes make roads treacherous in central and northern United States.

The city of  Minneapolis has been  buried under more than 13 inches of snow after being hit by a snowstorm. 

Two people were killed, hundreds of flights have been canceled and roadways have become treacherous in several midwestern states as a deadly storm system stretching from Gulf Coast to Great Lakes rolls across the central United States, bringing heavy snow, strong winds, rain and hail. 

All flights were grounded Saturday at Minneapolis-St Paul International Airport as a spring blizzard made it difficult to keep runways clear and planes deiced. Nearly 470 flights were canceled before one runway reopened  on Saturday night.

Blizzard conditions also forced the airport in South Dakota’s biggest city, Sioux Falls, to remain closed for a second straight day on Sunday.
