Head to high north facing slopes to find the best conditions.

Wet loose avalanches remain possible as warm temperatures continue.

Confidence

Moderate

Avalanche Summary

On Saturday, wet loose avalanches were observed to size 1. And on Friday, skiers remotely triggered a slab on a northeasterly lee ridge feature at treeline near Mt. Fisher.

Looking forward avalanche activity is expected to be limited to small, wet avalanches on steep slopes.

Snowpack Summary

The snow surface is either a thin crust or moist snow to 2500 m. High alpine north facing slopes may still hold dry snow above a thick crust from late March.

The snowpack is quickly disappearing below treeline.

Weather Summary

Sunday Night

Partly cloudy. 20 to 30 km/h southwest ridgetop wind. Freezing level remains above 2800 m.

Monday

Mostly cloudy with light rain possible. 30 to 50 km/h southwest ridgetop wind. Treeline temperature +4 °C. Freezing level above 2500 m.

Tuesday

Cloudy with up to 5 cm of wet snow above 2000 m. 30 to 50 km/h southwest ridgetop wind. Treeline temperature +2 °C.

Wednesday

Cloudy with flurries. 20 to 30 km/h southwest ridgetop wind. Treeline temperature +2 °C. Freezing level around 2000 m.

Terrain and Travel Advice

  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
  • Rocks will heat up with daytime warming and may become trigger points for loose wet avalanches.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

Avalanche Problems

Loose Wet

Wet loose avalanches are still possible as temperatures remain high and the snowpack has limited chance of refreezing overnight.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 1.5

Cornices

Cornices are weak and may break further back on ridgelines than expected. These large loads can trigger buried weak layers on the slope below.

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

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 3
