Denver International Airport is closed until further notice and more than 700 flights have been canceled as a major winter storm moves eastward across the Front Range.

Major freeways -- Interstates 25 and 70 -- are both closed in all directions out of Denver. A blizzard warning remains in effect for the Denver metro and parts of the Plains through 6 p.m. Wednesday. 

Classes were canceled across the area, including at major school districts like Denver Public Schools, Cherry Creek Schools, and Jefferson County.

Delays At DIA

A power outage Wednesday morning at DIA first caused hundreds of delays. Service was restored around 9:30 a.m., but by 11 a.m. the FAA decided to hold all traffic because of blowing snow, airport spokesman Heath Montgomery said. Then, at 12:18 p.m., officials closed the airport "until further notice."

"Weather and visibility are such that it is not safe for aircraft to arrive or depart at this time," the airport tweeted.

More than 700 flights have been canceled, which is about half of all the scheduled flights at DIA. And Pena Boulevard is impassable due to the weather. Officials advised travelers currently at the airport to "stay put" until conditions improve.

The airport has closed at least a handful of times because of snow. First in 2001, then again in 2003 and 2006.

Power Outages

The storm knocked out power to about 190,000 Xcel Energy customers across the metro area. A bit more than half, or 100,000 accounts, have been restored, says the company. But 90,000 are still without power and the company can't say when they'll get power back. 

"Not seeing much relief from the storm to start working that number down at this point," Xcel Energy spokesman Mark Stutz said earlier this morning. Most of those outages are on the north side of the metro, including in Boulder and Arvada.

Dangerous Roads
