Tetons

At the mid and upper elevations areas of unstable snow persist on steep, avalanche prone slopes underlain by a base of weak, faceted snow. Backcountry travelers could trigger hard slab avalanches one to three feet deep in these steep areas. Slides could be triggered by the first person on a slope or after a slope has been crossed multiple times. Avalanches are unlikely at the lower elevations.

High pressure aloft will begin to break down Monday with light snow possible by evening. Ridge crest winds will be light and temperatures will climb from the single digits in the morning to the mid teens during the day. Temperature inversions will hold cold air on the valley floors with morning temperatures near ten below zero then rising to the teens during the day. The General Avalanche Danger will continue at MODERATE above 8,000 feet due to areas of persistent unstable snow. Backcountry travelers on steep, avalanche terrain could trigger a hard-slab avalanche to three feet in depth. These slides could be started by a single person or, after a slope has been crossed multiple times. At the lower elevations the general avalanche hazard is LOW and avalanches are unlikely.
