The Park County Sheriff's Office in Livingston, Montana, posted photos on its Facebook page of a snow-covered interstate and asked motorists to drive safely. Police in Denver issued the same message to drivers after they received 96 traffic crash reports in the span of three hours.
"Rush hour is coming to a close, but the #snow is coming down and there are plenty of motorists still on the roads — keep your wits about you," the police department tweeted Thursday afternoon.

There have been hundreds of flights delayed at Denver International Airport and at least 100 flights cancelled according to FlightAware.
The National Weather Service said "moderate to heavy snow" is expected for the southeast part of the state into parts of the Central and Northern Plains. The snow will be accompanied by gusty winds which could make traveling difficult.

Weather.com warned that "dangerous blizzard conditions" are expected in the region through to late this week.
