Rising temperatures are increasing the chance of avalanches. Monitor the conditions and back off steep slopes as the surface becomes wet or slushy.

Avalanche Summary

There have been no recent reports of avalanches in the region. Avalanche activity is expected to increase with warming to mountain top on Tuesday.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Snowpack Summary

The surface snow will likely become wet due to warm temperatures and rising freezing levels to mountain top.

In the alpine, new snow from the weekend (we suspect up to 30 cm) sits over moist snow. Elsewhere, 10-15 cm sits above a firm rain crust. Below the crust is a rain-soaked snowpack.

Snow depths at treeline vary across the region from 65 cm to 150 cm.

Terrain and Travel Advice

  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

Avalanche Problems

Loose Wet

A moist or wet snow surface, pinwheeling and natural avalanches are all indications of a weakening snowpack.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2

Wind Slabs

Slabs may be possible to trigger at high elevations where dry snow has been loaded into leeward terrain features.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
