Avalanche Summary

New avalanche problems will develop Thursday afternoon, with wind slabs forming above the snow line and wet loose avalanches below.

A few small (size 1) skier-triggered slabs were reported on Mount Seymour on Tuesday.

Snowpack Summary

Climbing freezing levels are turning recent snow wet. Freezing levels will peak near 2000 m on Thursday morning before dropping in the afternoon as a windy storm brings 10 to 20 mm of precipitation. Expect rain up to at least 1500 m, with increasing, wind-affected snowfall at higher elevations.

Lower elevations are melting out quickly.

Cloudy with 1 to 3 cm of snow above 1300 m. 40 km/h southeast ridgetop wind. Treeline temperature -1 °C. Freezing level 1300 m.

Thursday

Cloudy with 10 to 20 mm of precipitation, snow possible above 1500 m. 60 km/h southeast ridgetop wind. Treeline temperature +1 °C. Freezing level drops from 2000 to 1500 m.

Terrain and Travel Advice

  • Avalanche danger is expected to increase throughout the day.
  • Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
  • Avoid freshly wind-loaded terrain features.

Avalanche Problems

Loose Wet

Rain falling on recent snow will likely trigger wet loose avalanches. Manage sluff carefully—wet snow can entrain significant mass.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2

Wind Slabs

The rain-snow line is uncertain, but reactive wind slabs could form at treeline and alpine elevations.

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2
