Summary

Weather Forecast

For Saturday, expect a mix of sun and cloud, alpine temperatures around 0C, and light west with occasional gusts.Â Sunday - Monday there will be a return to predominately cloudy skies with no significant precipitation.

Snowpack Summary

Despite the presence of weak facets and depth hoar near the ground, the weak layers in the snowpack are largely dormant right now. This is a result of past warming and rain, then cold temperatures and no significant snow for several weeks. Once the temperatures warm up significantly and/or new snow arrives then the weak layers will re-activate.

Avalanche Summary

No new avalanches reported or observed today.

Confidence

Problems

Deep Persistent Slabs

The lower half of the snowpack is weak due to the presence of basal facets and depth hoar. Natural and human triggering is unlikely as the weak layer is dormant, but it is still a good practice to avoid steep, open, rocky slopes with shallow snow.

Travel conditions are difficult at lower elevations and in the trees.Ski crampons make travel easier and safer on frozen surface conditions
