Lo esencial

Wet snow avalanches are possible on steep slopes across multiple aspects. Consider exiting the mountains if you are sinking into slushy snow or observe signs of wet avalanche activity. Overhanging cornices may be unstable, so give them a wide margin. Your best tools today are getting an early start & moving to gentler terrain or colder slopes if you observe signs of instability.

    Sunny conditions and warm temperatures will destabilize the snow surface, increasing the likelihood of wet-loose avalanches. The most unstable snow will likely be on solar aspects from the warmth and direct sunshine of the past several days—slopes oriented E-S-W. Humans may trigger these avalanches, or they can release naturally, particularly near trees or exposed rock/cliff bands. These avalanches begin at a single point and fan out, collecting debris as they move downslope. They are commonly small, but can pack a punch in the wrong terrain or push a rider into consequential areas.

    Watch for obvious signs that the warm sun is wetting the surface of the snow. Small roller balls or pinwheels of moist snow can be an early warning that loose snow slides may follow. If you find yourself sinking into wet, mushy snow, it's time to find a safe exit from the mountains. Pay attention to what's above you. You can largely avoid this problem by sticking to colder, shaded aspects or lower-angle terrain.  

    • CORNICES - Some of these monsters can break off naturally or by the weight of a person. Give all cornices a wide margin, and be careful along ridgelines as they can break much farther back than expected. Limit your exposure underneath or adjacent to them. A cornice fall could trigger a larger slab avalanche breaking deeper within the snowpack.

    Small to large wet-loose avalanches have been noted over the past three days across a variety of upper-elevation aspects.

Avalanche Discussion

Right now, we're experiencing a snowpack in the throes of change. Just like our feet, about to make the change from boots all season to a pair of flip-flops, that change usually isn't very pretty. This is a time to start early and be off steep slopes in the heat of the day.

For the first time in several days, overnight temperatures dropped well below freezing, and a harder refreeze of the snowpack has occurred. As the snow melts on sun-drenched slopes today, rocks, cornices, and other alpine hazards will also become unstable, so keep these in mind. Those refrozen cinnamon rolls now common on many slopes are not as soft as they look, so exercise caution on slopes with old wet-loose avalanche activity. With our snow line and coverage retreating, consider hazards you might encounter on your day, whether it's firm riding conditions in steep terrain or your sled overheating on our now nearly-grassy trailheads. Think about how you'd create a margin for dealing with them. Continue safe backcountry travel practices, including carrying the proper avalanche gear, moving one at a time in avalanche terrain, and communicating with other groups (and within your own group). Start your day early & being off steep solar slopes by afternoon.
