CASPER, Wyo — High wind and winter storm watches have been issued for southeast Wyoming, with impacts beginning late Wednesday into Friday, according to the National Weather Service (NWS) in Cheyenne.

Impacts will be strongest in the North Snowy Range foothills, including the I-80 corridor and towns of Arlington and Elk Mountain.

Platte County and the I-25 corridor, as well as areas west of I-25 in Laramie County, will also be impacted. 

“Strong crosswinds will be hazardous to lightweight and high-profile vehicles, including campers and tractor trailers,” the NWS said. Areas of blowing snow from recent snowfall could reduce visibility to less than a half mile at times.

A winter storm watch is in effect for the Snowy and Sierra Madre ranges, including Centennial and Albany, from Wednesday evening to Friday afternoon.

Total snow accumulations of 15 to 28 inches are possible along with winds gusting as high as 75 mph.

“Travel could be very difficult to impossible,” the NWS said. “Areas of blowing snow could significantly reduce visibility.”

Those recreating outdoors are also advised that blowing snow can create disorientation, and wind chills as low as 25 below zero could cause frostbite on exposed skin in as little as 30 minutes.
