SIDNEY, Neb. — High wind warnings remain in effect Friday across the Nebraska Panhandle, southeast Wyoming and northeast Colorado after powerful wind gusts Thursday evening caused hazardous travel conditions and damage across the region.

The National Weather Service said northwest winds of 35 to 45 mph with gusts approaching 70 mph will continue through Friday afternoon. The strongest winds were reported Thursday evening, including a 73 mph gust measured 9 miles south-southwest of Bushnell in Kimball County and a 67.9 mph gust at Sidney Municipal Airport.

Additional reports included gusts of 62 mph in Harrisburg, 60 mph near Dix and Albin, and multiple gusts exceeding 55 mph across Scotts Bluff, Morrill, Banner and Box Butte counties, as well as portions of southeast Wyoming and northeast Colorado.

The Kimball County Sheriff’s Department confirmed a semi-tractor-trailer was blown over Thursday evening near mile marker 14 on Interstate 80 due to the high winds. No injuries were reported.

Forecasters warned that strong crosswinds will remain dangerous for high-profile vehicles, including campers and tractor trailers. Blowing dust and reduced visibility are also possible, particularly in open areas.

In addition to travel hazards, the combination of strong winds, low humidity and dry fuels has created dangerous fire weather conditions. Officials warned that grassland fires could spread rapidly in areas that did not receive snowfall Thursday night.

High wind warnings remain in effect until 5 p.m. Friday across much of western and central Nebraska, southeast Wyoming and northeast Colorado. Red flag warnings and fire weather watches are also in place in portions of northeast Colorado through Friday evening.

Residents are urged to secure loose objects, avoid outdoor burning and use extreme caution while traveling.
