In sintesi

The weather forecast calls for a bit more precipitation and then a brief clearing. Wind slabs at uppermost elevations are the main concern.

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

Confidence

High - We have a good understanding of the snowpack structure and confidence in the weather forecast

Weather Forecast

Thursday Night: Mainly cloudy with scattered flurries or showers, moderate southeast wind, treeline high temperature 2 C, freezing level 1300 m.

Friday: Snow or rain, 5-15 cm, moderate southwest wind, treeline high temperature 0 C freezing level 1000 m.

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

Sunday: Flurries or rain showers, moderate south wind, treeline high temperature near -1 C, freezing level 900 m.

Avalanche Summary

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 seen extensive wind effect but we have received no alpine observations. Recent snow may contain and/or sit on a crust. Below the 1300 m elevation band the snow surface is likely moist or wet. 

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.
