Weather Forecast

Thursday and Friday: A mix of sun and cloud, but no precipitation expected. Moderate to strong westerly winds and freezing levels rising throughout Thursday reaching as high as 1500m on friday. Saturday: Increasing cloud with light precipitation possible by midday. Freezing levels dropping back down to valley bottoms.

Avalanche Summary

No recent avalanche activity has been reported. Isolated wind slabs may be susceptible to human triggering.

Snowpack Summary

Expect to find scoured areas, sastrugi, and hard or stiff wind slabs in exposed terrain. Recent warm temperatures and sun-exposure likely resulted in a surface crust, especially on southerly aspects. Surface hoar is probably growing on sheltered shady slopes. The mid and lower snowpack are generally quite strong.
