Heavy snow and strong wind have raised the risk of avalanches throughout the high country of western Wyoming.

The Bridger-Teton Avalanche Center has issued an avalanche warning through midnight Friday. The center advises against venturing into avalanche terrain in western Wyoming over the next couple days.

The center says avalanches could reach the highways over Teton Pass and through the Hoback and Snake River canyons.

Snow has been falling throughout the western Wyoming mountains, including as much as a foot in the Teton Range. The Tetons are forecast to get another 4-6 inches of snow.

The avalanche center rates the avalanche risk throughout the mountains of western Wyoming as high. That means natural avalanches are likely and human-triggered avalanches are very likely to occur.
