Hurricane-force wind downs power lines, fans wildfires in Colorado with more on way

FORT COLLINS, Colo. — Crews were mopping up Thursday but still bracing for more after hurricane-force wind downed power lines and fanned wildfires along the Colorado Front Range and onto the Great Plains.

Wind that in places topped 100 mph (160 kph) late Wednesday arrived after Xcel Energy protectively cut off power through much of its eastern Colorado service areas. The goal was to prevent downed lines from starting fires — and power lines were indeed blown down in several areas.

By Thursday afternoon, power was about 60% restored to the almost 700 miles (1,100 kilometers) of power lines the utility de-energized. Some 37,000 Xcel customers on the Front Range and into the Rocky Mountains were still without power.

Another round of outages was expected Friday, however, with a forecast for even stronger winds over a longer period.

While crews worked to restore power to customers already affected, even longer outages were likely Friday, the head of Xcel Energy-Colorado cautioned in a news conference.

''The power will not come back on the moment the wind event ends because we have to inspect the lines,'' said the utility's president, Robert Kenney.

In central Denver, the power was out overnight, furniture was blown off apartment balconies, at least one apartment window was blown out and the ground was littered with blown-down branches Thursday.

A grass fire on the south side of Cheyenne, Wyoming, prompted a neighborhood's evacuation for several hours Wednesday evening. No structures burned, however.

Powerful gusts Thursday prompted closures of Interstates 25 and 80 in southeastern Wyoming to lightweight, high-profile vehicles though not other traffic. Unladen tractor-trailers whose drivers ignore such warnings are often seen blown over on the windy state's highways, prompting jokes that the trucks are just taking a rest.

''If your commercial hauler is in need of a good night's sleep we would highly recommend the windblown plains of I-80, I-25, or I-90,'' the Wyoming Highway Patrol joked on Facebook, adding: ''For the low, low cost of a Driving on Closed Roads Citation ($1,000+).''

High winds and red flag fire warnings were in effect, meanwhile, across much of Kansas on Thursday. Blowing dust reduced visibility so much that a stretch of Interstate 70 near the state's western line with Colorado closed, the Kansas Department of Transportation said in a news release.

The release urged motorists to consider delaying non-essential travel.

Parts of southern Oregon and northern California including the San Francisco Bay area were expected to see several inches (centimeters) of rain and strong winds Friday and into the weekend.

Then on Christmas Eve, a Pineapple Express, a stronger atmospheric river that originates in the tropics near Hawaii, could arrive in northern California. The forecast brought hope to ski resort operators that much anticipated precipitation will extend into the Sierra Nevada, where very little snow has fallen this season.

Elsewhere, a blizzard was bringing as much as 8 inches (20 centimeters) of snow to northern North Dakota and Minnesota before it heads into Wisconsin and other areas eastward over the next couple days.
