The Colorado Avalanche Information Center said backcountry activities are not recommended in the Park and Gore ranges through Saturday.

BOULDER, Colo. — A powerful winter storm hitting the Colorado mountains has forced the Colorado Avalanche Information Center (CAIC) to issue its first avalanche warnings for the 2025-2026 season.

The warnings were posted Friday afternoon for the Park Range mountains around Steamboat Springs and Buffalo Pass, as well as the Gore Range stretching from the Wyoming border through most of the central mountains down to around Crested Butte. CAIC warned that backcountry travel and recreation are not recommended for those areas through at least Saturday. 

In the last week, CAIC said 139 avalanches had been reported. Forecasters said strong winds will pack the new snow, creating wind-drifted slabs on steep slopes and leading to “very dangerous avalanche conditions over a wider area.”

According to CAIC, people who do go out into the warned areas should avoid avalanche terrain and stay off and out of steep slopes and avalanche paths. 

Those who do go to the avalanche areas in the backcountry should bring avalanche safety equipment, including a transceiver, probe and shovel.

Areas of the mountains could see 12-24 inches of snow this weekend, according to 9NEWS Weather Impact Team Meteorologist Cory Reppenhagen.
