Yesterday's storm system brought 10 to 16 inches of snow with 1 to 1.5 inches of moisture to the mountains. Last night the Wyoming Department of Transportation triggered an avalanche in Glory Bowl that ran to the roadway. The new snow and strong winds have created dangerous conditions at the mid and upper elevations. Large to very large slab avalanches could be triggered by the weight of a single person. These slabs lie on persistent weak layers that formed earlier in the season and cannot be trusted. These dangerous slabs could be triggered on slopes that have been previously crossed by skiers, snowboarders or snowmobilers. Safe travel will require excellent terrain evaluation skills, restraint and a knowledge of the distribution of buried persistent weak layers. Avalanches are unlikely at the lower elevations.
