Avalanche Summary
No avalanches have been reported. Please submit any observations you have to the Mountain Information Network
here.Snowpack Summary
The warm storm early last week produced over 200 mm of precipitation that mostly fell as rain. This rain washed away much of the snowpack at lower elevations. The highest alpine terrain in the region more likely received heavy snowfall during the storm. This snowfall, paired with extreme winds out of the south/southwest is likely to have produced cornice growth along many ridgelines.Alpine areas near Squamish have the most snow, with around 70 cm of settled snow on the ground. In these areas there may be a crust lower in the snowpack, however it is likely now well bonded to the overlying storm snow. It is thought that there is insufficient snow for avalanches below 1500 m.
