The National Weather Service has issued a blizzard warning for north- and southeastern Colorado while most of the state is covered in a winter weather advisory. Heavy snow and strong winds are expected to continue throughout the day until about 5 p.m. on Sunday.

Forecasters are advising that commuters stay indoors.

"Only travel in an emergency. If you must travel, keep an extra flashlight, food and water in your vehicle."

The Colorado Department of Transportation has deployed its entire fleet to combat the storm with interstate highways being the top priority, and snow removal planned throughout the night.

9News reports that this will be the heaviest snow of the season for Denver with 6 to 11 inches of snow expected to fall before late Sunday evening. The Front Range is expected to accumulate 7 to 14 inches of snow while Douglas and Elbert Counties may see wind gusts up to 50 mph.

According to the National Weather Service, "the culprit is a deep upper low currently traversing toward the Four Corners region," and that much of the activity is confined to the Rockies as the "system feeds off enhanced moisture from the Gulf of Mexico."

One inch of snowfall per hour is possible with diminishing visibility into Sunday night.

Ann Williams, a spokeswoman for Denver's Department of Public Works said Denver's 70 snow ploughs are busy clearing major streets.

"We're seeing a lot of icy roads. The pavement is very cold and the snow is bonding to the pavement so we have a lot of slick conditions. We are trying to stay with it. The snow is coming down fairly fast and fairly heavy," Williams told The Denver Post.

Though the weather should taper off before Monday morning's commute, roads will be slick and another storm may move into the region on Tuesday.
