Avalanche Summary
No recent avalanches have been reported. However, the recent rain-on-snow event is suspected to have caused a natural, loose wet avalanche cycle. Looking forward, cooling temperatures are set to stabilize the existing snowpack while light new snow amounts may form touchy but thin new wind slabs in lee terrain at higher elevations.
Snowpack Summary
There are limited reports on snowpack structure at this time, except that recent heavy rainfall has saturated the snowpack at all elevations and washed away much of the snow at lower elevations. Travel below treeline is becoming more and more rugged, with many open creeks and early season hazards. Snow depth varies from 40-130 cm for elevations between 900m and 1200m across the region.
