Points saillants

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

    Wet loose avalanches are likely where precipitation falls as rain.

    As the upper snowpack and previously formed wind slabs become saturated, they will lose strength and are expected to become increasingly reactive, with the potential to produce large, destructive avalanches.

Confidence

Moderate

  • We are uncertain about how the snowpack will react to the forecast weather.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

No new avalanches have been reported since Saturday. We expect a widespread natural avalanche cycle to continue.

If you are heading into the backcountry, please share any observations with the Mountain Information Network.

Snowpack Summary

The rain continues to saturate the upper snowpack. There is 80 to 100 cm in the alpine and 20 to 40 cm at lower elevations, overlying a series of early March melt-freeze crusts.

A crust with facets may exist 100 to 200 cm below the surface, primarily on northerly aspects at higher elevations. This layer appears unreactive but continues to be monitored.

The mid and lower snowpack is otherwise strong and well settled.

Weather Summary

Cloudy. 10 to 30 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2400 m.

Thursday

Cloudy. 15 to 25 mm of precipitation as snow or rain at treeline. 60 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2100 m.

Friday

Cloudy. 10 to 45 mm of rain at treeline. 70 km/h southwest ridgetop wind. Treeline temperature 1 °C. Freezing level 2200 m.

Saturday

Mix of sun and clouds. 2 to 5 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice

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