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

Watch for fresh, reactive wind slabs forming at upper elevations as strong winds impact the region.

Confidence

Moderate

Avalanche Summary

A natural wet loose avalanche cycle occurred over the past few days with strong sun and warm temperatures.

Looking forward to Tuesday, wet loose avalanche activity may continue in steep terrain as temperatures stay warm. Watch for fresh, reactive wind slabs forming in lee areas as you transition into higher terrain where the surface snow remains dry.

Snowpack Summary

A crust or moist snow exists on all aspects and elevations except shady aspects in the alpine where dry snow can still be found.

The mid and lower snowpack are generally well bonded,

Weather Summary

Monday Night

Partially cloudy. Ridgetop winds southwest 20 to 50 km/h. Treeline temperature +3 °C. Freezing level 2500 m.

Tuesday

Mainly cloudy with sunny periods and light rain. Treeline temperature +3 °C. Freezing level remains at 2500 m.

Wednesday

A mix of sun and cloud with flurries, up to 5 cm accumulation. Treeline temperature -3 °C. Freezing level rises to 1300 m.

Thursday

A mix of sun and cloud. Treeline temperature rising to 0 °C. Freezing level rising to 1500 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Make observations and assess conditions continually as you travel.
  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.

Avalanche Problems

Wind Slabs

Be cautious as you transition into upper elevations where the surface snow remains dry. Southwest winds may form pockets of reactive slab in north-facing terrain features.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5

Loose Wet

Loose wet avalanche activity may continue in steep terrain where the surface snow remains moist and uncohesive.

Aspects: All aspects.

Elevations: Treeline, Below Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 1.5
