CHEYENNE, Wyo — A blizzard warning in southeast Wyoming has been extended through 5 a.m. Sunday morning in some areas, according to the National Weather Service (NWS) in Cheyenne.

I-80 from Arlington and Elk Mountain, as well as the towns of Rawlins, Sinclair and Hannah, will remain affected until 5:00 a.m. Sunday.

“Travel should be restricted to emergencies only,” the NWS said. “Widespread blowing snow could significantly reduce visibility and create whiteout conditions.”

Wind chills as low as 15 below zero could cause frostbite on exposed skin in as little as 30 minutes, the NWS advised.

I-80 also remains closed from Cheyenne to Rawlins, and eastbound from Evanston to Rawlins, as part of rolling closure. As of 3:00 p.m., WYDOT estimated the reopening time for I-80 to be between 8:30 p.m. and 10:30 p.m. Saturday.

I-25 is closed between Cheyenne and Glendo, and southbound from Douglas to Glendo, due to winter conditions. As of 12:30 p.m., the estimated reopening time  between 8:30 p.m. and 10:30 p.m. Saturday.

No unnecessary travel and closures to light, high-profile vehicles are advised on I-25 from Douglas to Buffalo.

Though the blizzard warning will expire for the Central Laramie Range and Southwest Platte County — including portions of I-25 near Bordeaux— 85 mph gusts will keep the area until a high wind watch until 5:00 p.m. Sunday.
