Pay attention to the impact of warm temperatures and back off avalanche terrain if you encounter signs of instability.




Avalanche Summary

On Thursday, numerous natural dry loose avalanche (size 1) were observed from the Coquihalla highway. No other avalanches were reported, but observation have been limited by stormy weather.

If you head into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Up to 30 cm of recent, low-density snow has been redistributed by variable alpine winds. Below the new snow are various old surfaces, including firm wind-affected snow, faceted crystals, and surface hoar, all of which may prolong the bonding between new snow and underlying surfaces.

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

With recent snowfalls, lower elevation areas may now be at the threshold for avalanches.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Avoid steep slopes when air temperatures are warm, or solar radiation is strong.
  • Closely monitor how the new snow is bonding to the old surface.


Storm Slabs

An icon showing Storm Slabs

Recent low-density storm snow has been redistributed by variable winds into deeper deposit in wind-loaded terrain. Warming on Saturday may settle the storm snow into a more cohesive slab, forming a more widespread storm slab problem.

Aspects: All aspects.

Elevations: All elevations.
