Avalanche Summary

No recent reports of avalanche activity.

Please continue to share any observations or photos on the Mountain Information Network.

Snowpack Summary

Last week's storm resulted in slabs at higher elevations (above 2000 m) where snow remained dry. At treeline and below (2000 m and lower) the snowpack has a frozen crust on the surface.

The mid-snowpack is well-settled. The lower snowpack consists of several crusts with weak faceted crystals above and below that are beginning to heal and bond to each other.

Snowpack depths are roughly 150 cm cm at treeline and tapers rapidly below 1500 m. This is about 60 - 70% of average.

Weather Summary

Tuesday Night: South wind strengthens to moderate, strong at high elevations. Trace of new snow. Freezing level near 1000 m. Treeline temperatures around -5 C.

Wednesday: Moderate to strong south wind at high elevations, lessening to moderate in the afternoon. 5 to 10 cm of new snow. Freezing level 1000 m, briefly rising to near 1300 m late in the day. Overcast. Treeline temperatures around -5 C.

Thursday

Mix sun and cloud. Dry. Cooler with treeline temps around -10 C. Light west wind.

Friday

Mix of sun and cloud. Dry. Treeline temps around -5 C. Light southwest wind.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.

Avalanche Problems

Wind Slabs

At higher elevations where the snow remains dry, southerly winds redistributed new snow into alpine lees. Wind slabs may be lingering.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible
