Weather Forecast

Moderate winds overnight tonight with a valley bottom freeze expected. Tomorrow will bring clear skies and above zero temps in the alpine. The winds will continue to flow out of the west and range from 20-25km/hr with gusts up to 60km/hr. Freezing level will reach 2400m.

Avalanche Summary

Loose wet on solar aspects up to sz1.5 and cornice collapses were noted.

Snowpack Summary

5-10 cm's came in from the last storm. This snow was very low density and easily blown around by the winds. There was significant recovery/refreezing last night which help up for most of the day. Windslabs start to appear at treeline and continue all the way up to the alpine. In the alpine, cornices have grown significantly. A few collapses were witnessed today, but no slabs were initiated.
