Avalanche Summary

No new avalanches have been reported.

Please submit your observations to the Mountain Information Network.

Snowpack Summary

20-40 cm of new snow has fallen in the alpine over the past week. Moderate southwest winds are expected to have formed reactive wind slabs with much of this recent snow. The new snow sits on an older layer of settled storm snow from last week, which itself overlies a now 40-60 cm-deep melt freeze crust. This crust is widespread with the possible exception of high elevation north aspects. Most of the recent precipitation has fallen as rain at 1000 m and below.

At lower elevations, ongoing warm weather has been melting the snowpack away.


Wind Slabs

An icon showing Wind Slabs



Expected Size

1 - 2

Recent snowfalls coupled with bouts of strong southwest wind have likely developed new wind slabs at higher elevations. Expect snow amounts and the effects of wind loading to increase as you gain elevation.

  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Be cautious as you transition into wind affected terrain.

Loose Wet

Expected Size

1 - 1.5

The likelihood of loose wet avalanches will depend on the extent of overnight crust recovery and the pace at which it warms up through the day.

  • Use caution above cliffs and terrain traps where small avalanches may have severe consequences.
