CHEYENNE, Wyo. (AP) — A large spring snowstorm delivering everything from heavy snow and high winds to freezing rain and possible tornadoes was causing travel problems from Wyoming to Chicago on Tuesday.
In Wyoming, a 100-mile stretch of Interstate 25 between Cheyenne and Douglas was closed as well as a 125-mile section of I-80 between Laramie and Rawlins. Many smaller highways in a majority of the state also were closed, slick or had no travel advisories.
More than a foot of snow had fallen as of midmorning in Lander. In Pine Bluffs, near the Nebraska border, wind has created 1- to 2- foot drifts out of the snow that has fallen there.
"I'm pretty confident that this particular storm is more widespread and has caused more travel problems and closures than any storm we've had this calendar year certainly," Bruce Burrows, spokesman for the Wyoming Department of Transportation, said.
Freezing rain, snow and strong winds, were hitting Kansas and South Dakota, where numerous local elections were postponed. Some schools in Minnesota dismissed students early as travel conditions deteriorated.
Snow in the Denver area has been lighter than expected but around 500 flights have been cancelled at Denver International Airport and deicing was delaying departures.
Flights bound for Chicago's O'Hare International Airport, meanwhile, were being delayed an average of nearly four hours because of dense fog.
Tornadoes were also possible in parts of Texas, Oklahoma and Arkansas later in the day.
As the storm moved into Colorado Monday night, two tornadoes were reported near Akron on eastern Colorado's plains though forecasters haven't confirmed the twisters yet. A trailer home rolled over onto its top, a roof blew off a barn and six power poles were toppled, Washington County undersheriff Jon Stivers said.
A motorcycle dealership partially collapsed in Pueblo, Colo., where winds gusted to 64 mph.
In Wyoming's Sweetwater County, wind gusts up to 71 mph damaged a marina at Flaming Gorge Reservoir and broke windows at the Western Wyoming Community College in Rock Springs, according to the National Weather Service.
About 1,200 customers in Rock Springs lost power Monday afternoon after winds broke a cross-arm at the top of a power pole. Some residents in Lamont, a small town north of Rawlins, were without power Tuesday. Repair crews used snowcats to access the downed lines, Rocky Mountain Power Company spokesman Jeff Hymas said.
Cold temperatures that made it feel more like January or February engulfed the entire state with many areas expecting daytime temperatures in the teens and 20s. A record low temperature was set at Douglas in central Wyoming when the temperature dropped to 14 degrees early Tuesday. The previous record was 17 set in 2000.
The same storm system toppled trees in San Francisco, produced gusts over 80 mph in southern California and kicked up a dusty haze in Phoenix on Monday, closing a stretch of Interstate 40 in northern Arizona.
