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

Isolated thin wind slabs may linger in alpine features. Carefully evaluate your line for slabs before you commit to it

Periods of low danger are a good time to explore more challenging terrain

Confidence

Moderate

Avalanche Summary

No new avalanches were reported by Thursday at 4 pm.

If you are headed into the backcountry please consider making a MIN post with photos and observations from the day. The information is very helpful for forecasters!

Snowpack Summary

A few centimeters of snow covers a layer of surface hoar above a thick melt-freeze crust at all elevations. On shaded northerly slopes in the alpine, you may find 15 cm of dry snow overlying a thin crust.

A substantial crust up to 30 cm thick, sits 50 to 90 cm deep and is well-bonded to surrounding snow. The mid and lower snowpack is generally well consolidated.

Treeline snow depths range from roughly 160 to 220 cm around the Coquihalla and 100 to 150 cm around Manning Park.

Weather Summary

Thursday Night

Mostly clear skies. 20 to 25 km/h northwest ridgetop wind. Treeline temperature -7 °C. Freezing level at 900 m.

Friday

Mostly sunny. 15 to 25 km/h northeast ridgetop wind. Treeline temperature -9 °C.

Saturday

Partly cloudy. 20 to 30 km/h northeast ridgetop wind. Treeline temperature -8 °C.

Sunday

Partly cloudy. 30 to 40 km/h northeast ridgetop wind. Treeline temperature -10 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.

Avalanche Problems

Wind Slabs

Moderate westerly winds and a few centimeters may have built isolated wind slabs over a crust in the alpine. Investigate the bond of new snow to the crust below before committing to your line.

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

Elevations: Alpine.

Likelihood: Unlikely

Expected Size: 1 - 1.5
