Regions

South Coast, Powell River, North Shore, Sasquatch, Tetrahedron, Skagit.

High avalanche danger. Avoid avalanche terrain and exposure to overhead hazards like cornices and runout zones.

Confidence

High

  • We are confident the snowpack will rapidly weaken with the forecast weather.
  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

A few natural storm slabs were reported on Sunday.

Expect widespread natural avalanche activity to continue.

Snowpack Summary

40 to 70 mm of precipitation will fall by the end of the forecast period. Freezing levels will rise between 1800 and 2500 m. Expect wet, unstable snow in the upper snowpack below these elevations.

A thick, widespread crust, buried in early March, is 30 to 80 cm deep. Below it, the snowpack is generally settled and well-bonded.

Weather Summary

Monday Night

Cloudy. 20 to 25 mm of rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 1900 m.

Tuesday

Cloudy. 20 to 35 mm of rain at treeline. 40 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 2300 m.

Wednesday

Cloudy. 60 to 70 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2200 m.

Thursday

Cloudy. 75 to 90 mm of rain at treeline. 50 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 2300 m.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy rain.
  • Keep in mind that the high density of wet avalanches can make them destructive.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.

Problems

Wet Slabs

Wet Slab avalanches are the release of a cohesive layer of snow (a slab) that is generally moist or wet when the flow of liquid water weakens the bond between the slab and the surface below (snow or ground). They often occur during prolonged warming events and/or rain-on-snow events. Wet Slabs can be very unpredictable and destructive.

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.
