Watch for wind slabs in exposed terrain features as you head to higher elevations. They may be small but sensitive to human triggers.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported.

If you do head into the backcountry please consider submitting observations and/or photos on the Mountain Information Network.

Snowpack Summary

Higher elevations hold small wind slabs in exposed terrain. Below, previous storm totals have bonded well to old surface.

The mid and lower snowpack is made up of a series of crusts and strong, rounded grains. The snowpack is generally well consolidated.

Overall, the snow depth remains shallow, especially on south facing slopes. Below treeline, expect to encounter dirt or shallow, moist snow. Early season hazards are just below the surface.

Weather Summary

Tuesday Night

Partly cloudy. Possible flurries with freezing levels dropping from 2500 m to 2000 m. Southerly winds, 40-60 km/h.

Wednesday

Mostly cloudy. Trace amounts of snow possible. Freezing levels will vary significantly from 2500 m in the Coquihalla to 1500m at Allison Pass. Treeline temperatures around 0 °C. Southerly winds, 50-70 km/h.

Thursday

Mostly cloudy with possible afternoon sunny breaks. Trace amounts of snow possible. Freezing levels around 1800 m. Treeline temperatures around 0 °C. Southwest winds, 30-40 km/h.

Friday

Partly cloudy. Freezing levels around 2100 m. Treeline temperatures around 3 °C. Southerly winds, 30 km/h.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
  • Travelling on skis is hazardous due to a very shallow mountain snowpack.

Avalanche Problems

Wind Slabs

Light snowfall and strong winds may have built wind slab on north and east facing terrain features. During periods of very strong wind, expect wind slabs to be located lower on lee slopes.

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

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
