Avalanche Summary

No recent avalanches have been reported in the region. Expect  thin loose wet avalanches in the alpine and tree line elevation bands in the coming days.

Snowpack Summary

Last weekend's storm delivered 20-30 cm of wet snow in alpine terrain and rain elsewhere. The wet snow has frozen and stabilized the snowpack in all but the highest terrain where isolated storm and or wind slabs may sit above a rain crust. High freezing level and continued precipitation over the coming days will start to break down the recent crust formation.
