Regions: Coquihalla, Harrison-Fraser, Manning, Sasquatch, Skagit, Stave.

New snow and wind may build new isolated pockets of wind slab in the alpine.

A surface crust at most elevations will limit potential for avalanches.

Confidence

Moderate

Avalanche Summary

Strong sunshine and rising temperatures produced loose wet avalanches over the past few days.

If you head into the backcountry, please submit any observations or photos to the Mountain Information Network.

Snowpack Summary

A widespread surface crust likely exists at all elevations, except on high north-facing slopes which is expected to limit avalanche activity. Small pockets of wind-affected dry snow still exist on north-facing alpine slopes.

Below treeline elevations have minimal snow cover, if any at all. Expect challenging travel conditions with hazards like rocks, stumps and open creeks.

Weather Summary

Monday Night

Cloudy with 5 to 20 cm of new snow. 30-50 km/h southwest ridgetop wind. Freezing level drops to 700 m by the morning.

Tuesday

Mostly cloudy with up to 5 cm of snow. 20-30 km/h northwest ridgetop wind. Treeline temperature -1 °C. Freezing level around 1200 m.

Wednesday

Sunny with cloudy periods. 10-20 km/h northerly ridgetop wind. Treeline temperature -1 °C. Freezing level around 1700 m.

Thursday

Clear skies. 10-20 km/h northerly ridgetop wind. Treeline temperature -1 °C. Freezing level around 1800 m.

Terrain and Travel Advice

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Make observations and assess conditions continually as you travel.

Avalanche Problems

Wind Slabs

New snow up to 20 cm and winds from the northwest may have formed wind slabs in lee terrain features in the alpine and treeline.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5
