Regions: Sea To Sky.

Rising temperatures could mean that avalanche hazard increases throughout the day. Choose more conservative terrain if significant warming is experienced.

Confidence

Moderate - Freezing levels are uncertain

Avalanche Summary

Several natural and explosives triggered avalanches to size 2, and one human triggered size 1 avalanche were reported in the region on Wednesday.A few size 1 explosives triggered avalanches were reported in the region on Tuesday.

Snowpack Summary

40-60cm of recent storm snow 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. A sun crust likely exists on the surface on south facing slopes at all elevations.

Avalanche Problems

Persistent Slabs

40-60 cm of recent snow sits on a weak layer that may be still be reactive, especially in wind loaded areas and as temperatures rise.
Watch for signs of instability, such as whumpfing, cracking, or recent avalanches.Be careful with wind loaded pockets, especially near ridge crests and roll-overs.Watch for clues, like sluffing off of cliffs, that the snowpack is warming up.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
