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

Snowfall may vary across the forecast area.

If you don't see wind blowing snow around, and less than 15 cm of new snow, avalanche danger will be lower.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in this region.

We expect that with the incoming snow, human-triggered avalanches will be possible.

If you do go into the backcountry, please consider submitting a MIN report.

Snowpack Summary

Some new snow (15-20 cm west of Hope, 5-10 east) covers a robust crust that exists up to mountain tops. Expect this new snow to be wet at low elevations, and get drier as you travel higher.

Where snow still existed below treeline, it was isothermal or refrozen. Even with some new snow at lower elevations, travel will remain challenging.

Weather Summary

The snowfall amounts below are for west of Hope. east of Hope, expect half the snow or less.

Saturday Night

Cloudy. 5 cm of snow expected above 500 m. Light to moderate southwest ridgetop wind. Treeline temperature around -2 °C.

Sunday

Cloudy. 10-15 cm of snow expected above 750 m. Moderate southwest ridgetop wind. Treeline temperature around -3 °C.

Monday

Mostly sunny. 10-15 cm of snow expected overnight above 750 m. Light to moderate north or northeast ridgetop wind. Treeline temperature around -4 °C.

Tuesday

Mostly sunny. No new snow expected. Light northeast ridgetop wind. Treeline temperature around -8 °C. Freezing level between 500 and 1000 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Expect shallow snow cover that barely covers ground roughness.

Avalanche Problems

Wind Slabs

In areas that see 15 cm or more of new snow, human-triggered avalanches will be possible where wind transport is forming deeper deposits in leeward terrain features.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2
