Regions

Coquihalla, Harrison-Fraser, Manning, Skagit.

Temperatures continue to climb, keeping avalanche danger elevated.

Confidence

Moderate

Avalanche Summary

Several large (size 2) glide slab avalanches have occurred in the Coquihalla area over the past few days.

A large (size 2) natural wet slab avalanche was reported in the Coquihalla area. It is suspected this avalanche was initiated by small loose wet sluffing, that then triggered a larger avalanche.

Snowpack Summary

5 to 15 cm of moist snow sits on a thin decomposing melt-freeze crust at all elevations.

The mid and lower snowpack contain several crusts that are not concerning. The snowpack remains shallow for this time of year.

Weather Summary

Sunday Night

Cloudy with up to 2 mm of rain. Southwest alpine wind, 30 to 50 km/h. Freezing level rising to 2800 m.

Monday

Mainly sunny around Allison Pass, mainly cloudy around Coquihalla, no new precipitation. Southwest alpine winds, 30 to 50 km/h. Freezing level rising to 3000 m.

Tuesday

Clearing through the day, up to 3 mm of rain. South alpine winds, 20 to 40 km/h. Freezing level falling to 2500 m.

Wednesday

Mix of sun and clouds, trace of rain. Southeast alpine winds, 40 to 60 km/h. Freezing level 2500 m.

Terrain and Travel Advice

  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.
  • Avoid areas with overhead hazard.

Problems

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
