Early season conditions in February! Snowpack heights are extremely low at lower elevations. Some "acceptable" skiing can be found in the Alpine with dust on crust conditions. Travel conditions are generally poor.




Avalanche Summary

Just a few loose dry naturally triggered avalanches were observed in steep terrain on N aspects today. These slides ranged from size 1 to 1.5.

Snowpack Summary

The recent storm snow is settling and now averages 5 to 15cm over the Feb 3 crust. This crust is supportive to skiers above 2100m and extends at least as high as 2500m. The bond at the storm snow - crust interface is mainly good, except on steep northerly aspects in the alpine. Very isolated wind slab development was observed today in the alpine in wind prone areas.

Weather Summary

Wednesday will be mostly cloudy with temps between -5 and -10. Winds will be light from the SW at ridgetop. Very light flurries will bring only trace amount of new snow.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Wind slabs may be poorly bonded to the underlying crust.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Be carefull with sluffing in steep terrain, especially above cliffs and terrain traps.
  • In areas where deep persistent slabs may exist, avoid shallow or variable depth snowpacks and unsupported terrain features.


Wind Slabs

An icon showing Wind Slabs

Light winds and less than forecasted snow amounts will keep this problem more isolated to cross loaded and lee features in the alpine.

Aspects: All aspects.

Elevations: Alpine.


Unlikely - Possible

Expected Size

1 - 2

Persistent Slabs

An icon showing Persistent Slabs

This will still be an issue in areas that escaped the heat, as there is no previous crust to hold the snowpack together.

Aspects: North, North East, East, West, North West.

Elevations: Alpine.



Expected Size

1.5 - 2.5

Deep Persistent Slabs

An icon showing Deep Persistent Slabs

This layer is shielded by 2 crusts, but is still triggerable from thin to thick transitions. Very much a low probability, high consequence situation.

Aspects: All aspects.

Elevations: Alpine.


Unlikely - Possible

Expected Size

2 - 3
