Tetons

At the mid and high elevations, skiers and riders have the potential to trigger pockets of dense surface slabs to depths of eighteen inches. These slabs will be most susceptible in steep couloirs, in cliff areas, and in steep terrain that shows signs of wind loading. At low elevations, isolated pockets of shallow slab could be triggered in very steep areas.

A winter storm watch is in effect for the region from early Sunday morning through Monday afternoon. Heavy snowfall and strong west winds, with averages near thirty miles per hour are expected on Sunday. Temperatures are to be warm with mountain highs near thirty degrees and valley temperatures above freezing. The general avalanche hazard is likely to increase to Considerable in the Teton and Southwest Trails areas on Sunday as new snow and strong winds rapidly load the existing slabs that lie in the backcountry. Depending on the timing of the new snow, slab depths could grow to thirty inches and will become more sensitive as the day progresses. In the Togwotee pass area, the hazard is expected to increase to Moderate as slab depths increase to potentially eighteen inches in steep loaded terrain.
