Moderate

Avalanche Summary

The avalanche cycle observed on the weekend and earlier in the week with the warming event has tapered. There is no new avalanche activity to report.

Snowpack Summary

Rain has created a moist or wet upper snowpack at all elevations. A weak surface crust may have formed overnight but will break down quickly throughout the day.

There is a layer of sugary facets that are buried 30-50 cm deep and in some places sits on a crust.

The middle and lower snowpack contains a series of crusts and faceted snow. It is likely moist to ground. Expect snow depth at treeline to be 70 to 120 cm.

Terrain and Travel Advice

  • Keep in mind that wet avalanches can be destructive due to their high density.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

Avalanche Problems

Wet Slabs

Wet slab avalanches could fail on or step down to buried weak layers in the mid and lower snowpack resulting in large avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2

Loose Wet

As the warm temperatures continue, wet loose avalanches are still possible from steep terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
