Regions

Coquihalla, Manning, Skagit.

Avoid all avalanche terrain.

Very dangerous avalanche conditions have developed with a combination of heavy precipitation and strong winds.

Confidence

Low

  • Uncertainty is due to how the snowpack will react to the forecast weather.
  • Forecast precipitation (either snow or rain) amounts are uncertain.

Avalanche Summary

No new avalanches were reported, but observers in the Zoa area on Saturday were reporting heavy wind transport of snow.

On Thursday, there was a skier-triggered wind slab near Zoa peak (see photos). It was triggered on a convexity and spread far across the slope. The skier was uninjured. Read the full report here.

For Monday the rising freezing levels heavy rain, and strong winds will create dangerous avalanche conditions.

Snowpack Summary

Heavy rainfall is saturating the upper snowpack and loading 30 to 60 cm of recent storm snow. With freezing levels near 2200 m, rain is expected even at upper elevations.

The mid-December crust is 100 to 250 cm deep. This crust is 30 cm thick and well-bonded to the snow above.

Weather Summary

Sunday Night
Cloudy. 15 to 80 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2200 m.

Monday
Cloudy. 15 to 80 mm of rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2200 m.

Tuesday
Mostly cloudy. 2 to 20 mm of rain at treeline. 50 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level 2900 m.

Wednesday
Mostly sunny. 50 km/h west ridgetop wind. Treeline temperature 4 °C. Freezing level 2800 m.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Avoid areas with overhead hazard.
  • Keep in mind that the high density of wet avalanches can make them destructive.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.

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.
