    Recent strong southerly wind has likely created windslabs slabs at uppermost elevations in lee terrain.

Confidence

High - Confidence is due to a stable weather pattern with little change expected.

Friday Night: Mainly cloudy with flurries, light west wind, treeline high temperature -1 C freezing level 800 m.

Saturday: Cloudy with sunny breaks, moderate southwest wind, treeline high temperature 3, freezing level 1300 m.

Sunday: Flurries or rain showers, moderate southwest wind, treeline high temperature near 2 C, freezing level 1100 m.

Avalanche Summary

There have been no reports of avalanche activity on Thursday and Friday.

On Wednesday there were reports of a few explosives controlled size 1-1.5 storm slab avalanches at 1200 m on a west aspect. As well, there were several MIN reports outlining easily triggered storm slabs at treeline during Tuesday afternoon's storm. Check out the MIN reports here and here. 

Snowpack Summary

Snow at uppermost elevations from earlier this week has likely been wind affected. Recent snow may contain and/or sit on a crust. Below the 1300 m elevation band the snow surface is likely moist, wet or refrozen as a surface crust. 

The remainder of the snowpack is well-settled.

Terrain and Travel

  • Be careful as you transition into wind affected terrain.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
