Meteorologists call storms like this one a "bomb cyclone," a winter hurricane that forms when the barometric pressure drops 24 millibars in 24 hours. "So far, we have received 110 traffic crash reports and #Denver remains on #AccidentAlert," the Denver Police Department said on Twitter.
"If you absolutely have to head out, please be cautious — it's still #snowgoing out there. Turn your lights on, set the wipers on high & don't forget the extra stopping distance. #BombCyclone" All six runways at Denver International Airport were shut down, along with the main road into the airport due to drifting, blowing snow. An airport spokesman said 1,339 flights had been canceled as of mid-afternoon.
All school districts in the seven-county Denver metropolitan were shuttered, along with most city and state government offices and many businesses. WIDESPREAD POWER OUTAGES
Utility company Xcel Energy said about 130,000 commercial and residential customers in Colorado were without power due to high winds and wet heavy snow. "Limited visibility has affected our ability to respond," Xcel Energy spokesman Mark Stutz said, adding it was unclear when power would be restored.
The police department in Northglenn, Colorado, tweeted a picture of a large tree that fell on a home, breaking through the roof. It was not immediately clear if anyone was hurt. Interstate 70 was closed east of Denver to the Kansas state line and sections of Interstate 25 were also shut down, according to Colorado Department of Transportation.
"They typically do get strong systems this time of the year in that part of the country, but this one is may be a notch stronger than what you typically see," said meteorologist Marc Chenard of the weather service's Weather Prediction Center in College Park, Maryland. Forecasters said they expect winds of up to 70 miles per hour (110 kph) to sweep across a wide area of states to the south, including New Mexico and parts of Texas, Oklahoma and Kansas.
"Pretty much through much of the Plains there's going to be a threat for potential power outage issues," Chenard said. More than 100,000 electric power customers in the Dallas-Fort Worth area were left in the dark early on Wednesday after a line of rain squalls associated with the system moved through the area.
The storm was also expected to bring heavy rain to areas of eastern Nebraska, Iowa, Wisconsin and Minnesota that already have a good deal of snow on the ground, raising the threat of river flooding, the weather service said. The storm system is expected to weaken by Thursday as it moves over the Tennessee River Valley, bringing mostly rain from Michigan southward to the Gulf Coast and some remaining snow only in the far northern parts of the country, the weather service said.
