Avalanche Summary

No recent notable avalanches have been reported.

Snowpack Summary

Surface snow in the past few days has undoubtedly become moist or wet on all aspects to mountain top with sunny skies and a high freezing level. Depending on the time of day, you may find the surface to be moist or be a frozen crust. The overall snowpack is well settled. Cornices formed or have grown more overhanging with the snowfall at the end of last week. They become touchier as they grow in size, as the temperature rises, and/or as they are impacted by the strong late-winter sun.

Avalanche Problems

Loose Wet

Sunshine and warm temperatures will weaken the surface snow surface.

Use caution above cliffs and terrain traps where small avalanches may have severe consequences.Minimize exposure to steep, sun exposed slopes when the solar radiation is strong.

Aspects: North, North East, East, South East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5

Cornices

Warm temperatures and sunshine will make already large and overhanging cornices ripe for triggering.

Give cornices a wide berth when traveling on ridges.Cornices become weak with daytime heating, so travel early on exposed slopes.

Aspects: North, North East, East, South East, South.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2
