CASPER, Wyo. - A holiday snowstorm that caused havoc on Thanksgiving by shutting down a significant stretch of Interstate 80 is expected to persist today. The storm has resulted in travel restrictions across many roads in Wyoming, prompting warnings and advisories from the Wyoming Department of Transportation (WYDOT).

District 2 of WYDOT, which covers Natrona County and surrounding areas, has reported treacherous road conditions due to slick spots, drifted snow, and strong winds. The department strongly advises against unnecessary travel on Interstate 25 from Glenrock to the south, cautioning of black ice conditions all the way north to Casper. Similar advisories have been issued for WYO 59 from Douglas to the Campbell County line, U.S. 18/20 from Interstate 25 to Lost Springs, and US 26 from Interstate 25 to Guernsey. Reports of black ice have also been received for WYO 259.

As of 6 a.m., all roads in the state have been reopened, with the exception of seasonally closed roads and WYO 28 from Farson to South Pass, as indicated on WYDOT's road closure site. However, restrictions remain in place primarily for light, high-profile vehicles on Interstate 80, U.S. 287, U.S. 30 from Rawlins to Laramie, WYO 34 from Laramie to Wheatland, and WYO 131 in Lander.

The WYDOT site highlights the primary advisories on Interstates 25 and 80 as black ice, the need to refrain from unnecessary travel, and the extreme risk of blowovers for vehicles.

The Wyoming Highway Patrol (WHP) reported multiple crashes on Interstate 80 between Cheyenne and Laramie around 4 p.m. on Thursday. However, by 2 a.m., most of the vehicles involved in the pileup had been cleared, and by 6 a.m., WYDOT was no longer reporting any closures. Fortunately, the WHP confirmed that there were no known serious injuries resulting from the accidents.

According to the National Weather Service in Riverton, more snow is expected today, particularly in central and southeastern Wyoming. Casper and Cheyenne could receive up to an additional 2 inches of snow.

As travelers navigate the wintry conditions, it is essential to stay updated on road conditions and heed the warnings and advisories issued by authorities to ensure their safety.
