Points saillants

Watch for new wind slabs forming, as this is when they are most reactive.

Freezing levels are variable throughout the region, surface conditions are your best indicator for avalanche type.

    New wind slabs will likely build through the day with continued snow and wind.

    With continued daytime warming and high freezing levels, loose wet avalanches are possible out of steep terrain.

Snowpack Summary

In the alpine, up to 30 cm of wind affected snow is topped by a variably breakable crust caused by recent strong winds and above freezing temperatures. At lower elevations, the top 10-20 cm of snow is moist.

The mid and lower snowpack contains various old crusts and is generally well-settled and stable.

Confidence

Moderate

Avalanche Summary

Multiple new wet loose and glide slab avalanches (Size 1 to 2) have been reported in the Coquihalla and Fraser Valley area from the recent warming period.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
