Highlights

The avalanche danger will rise as the day warms and unstable conditions develop on steep slopes that face the sun. Natural and human triggered wet snow avalanches will become likely later in the day. Some of these avalanches could become large enough to bury or injure a person. Avoid traveling on, or under, very steep and sunny terrain as the day heats up. Wind slabs up to a foot deep are still lingering in some very steep upper elevation terrain.

    Wind slabs were formed 36 hours ago in the upper elevations of the Tetons by strong westerly winds and new snow. Although they are becoming more difficult to trigger, skiers and riders still have the potential to trigger wind slabs up to a foot deep on very steep (>35°) and wind loaded slopes above 9,000’. Likely trigger spots include convex starting zones, cross loaded couloirs, and steep terrain below cliff bands. Warm temperatures and direct sun may increase the sensitivity of lingering slabs during the heat of the day. Carefully evaluate steep, upper elevation terrain for signs of unstable wind drifted snow such as cracking or hollow sounding snow. Consider moving to lower angle terrain if these signs are present.

    Wind slabs will be possible in terrain features like this today.

    Above freezing temperatures and mostly clear skies will make natural and human triggered wet avalanches likely on steep slopes that face the sun today. The majority of these avalanches will be on the smaller side, yet some could grow large enough to bury or injure a person on large south facing terrain features. These avalanches are most likely to begin around rocks or trees and can entrain large amounts of snow as they move downhill. Temperatures below 9,000’ rose above freezing yesterday morning and have been hovering around the freezing mark all night. Thin surface crusts that formed overnight will break down quickly as the day warms leading to unstable conditions on sunny slopes. Be on the lookout for signs of warming such as natural wet avalanches or slushy unconsolidated snow. Consider moving to shaded terrain or exiting the mountains if these signs are present. Carefully evaluate the terrain above you today given the potential for natural activity.

    Loose snow avalanches similar to these will become likely on steep, rocky, and sunny slopes as the day warms.
