Regions: Sea To Sky.

Although the storm has eased off, storm slabs are still likely to be encountered and could be reactive to human triggering, especially in wind loaded areas and as temperatures rise.

Avalanche Summary

Several explosives triggered avalanches to size 2 were reported in the region on Wednesday.A few size 1 explosives triggered avalanches were reported in the region on Tuesday.

Snowpack Summary

20-35 cm of new snow fell between Tuesday morning and Wednesday morning. This brings total recent snowfall amounts to approximately 40-60cm, which likely sits on a sun crust on south facing slopes and surface hoar (feathery crystals) in sheltered and shaded areas. The surface hoar is reportedly most prominent at treeline and below.Recent winds will have redistributed the new snow, forming storm slabs. Expect to find deeper deposits of snow in wind loaded terrain.

Avalanche Problems

Storm Slabs

Expect to find deeper deposits of new snow and more reactive slabs in wind loaded areas.
Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Watch for signs of instability, such as whumpfing, cracking, or recent avalanches.
