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

Cornices may be difficult to identify from the top of a ridge, so it's best to keep a safe distance when traveling along ridgelines. Learn more about spring snowpack conditions here.

Avalanche Summary

No new avalanches were reported on Monday.

Check out this MIN report showing a couple of old large slabs failing on a crust on northerly aspects at treeline.

NOTE: Observations are currently very limited in this region. Make observations and continually assess conditions as you travel.

Snowpack Summary

A typical spring diurnal cycle is underway.

High freezing levels have formed a surface crust everywhere except possibly the highest north-facing terrain.

The snowpack is generally well-settled and strong, although dormant weak layers may still exist in some areas.

Sustained high freezing levels with poor overnight recovery have the potential to awaken dormant weak layers.

Lower elevations are melting out rapidly.

Weather Summary

Tuesday Night

Mostly clear. 20 to 30 km/h southwest ridgetop wind. Treeline temperature 0 °C. Freezing level 1500 m.

Wednesday

Sunny. 20 to 30 km/h northeast ridgetop wind. Treeline temperature 4 °C. Freezing level 1800 m.

Thursday

Sunny. 20 to 30 km/h northeast ridgetop wind. Treeline temperature 6 °C. Freezing level 2200 m.

Friday

Sunny. 10 to 20 km/h southwest ridgetop wind. Treeline temperature 8 °C. Freezing level 2800 m.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.

Avalanche Problems

Cornices

Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

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

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 2.5
