Laramie, Wyoming – Mountain travel across southeast Wyoming will grow increasingly hazardous by late Monday morning as heavy snow begins piling up in the Sierra Madre and Snowy ranges, with impacts expanding into the Laramie Range by nightfall.
According to the National Weather Service in Cheyenne, a Winter Weather Advisory runs from 11 a.m. Monday to 5 p.m. Tuesday for the Sierra Madre and Snowy Range, including Centennial and Albany, where 6 to 10 inches of snow are expected and locally higher totals are possible on the peaks. The North Laramie Range near Garrett comes under advisory at 5 p.m. Monday, with 5 to 8 inches likely through 5 p.m. Tuesday.
By 11 p.m., snow spreads into the South Laramie Range, including the Interstate 80 Summit between Cheyenne and Laramie. That corridor could see 2 to 4 inches by late Tuesday afternoon, creating slick bridges and reduced visibility for both the morning and evening commutes.
Blowing snow may disorient hikers, hunters and snowmobilers in the backcountry. Drivers should slow down, carry winter survival gear and check 511 for updated road conditions. Advisories remain in effect through Tuesday afternoon, and additional alerts could follow if snowfall rates increase.
