Avalanche Summary

No new avalanche activity to report from Sunday or Monday.

Snowpack Summary

The current snow surface is quite variable. On higher north aspects above 2000 m you may find some dry snow. Some of this has been redistributed by southwesterly winds which may have formed isolated thin wind slabs. Expect to see a supportive crust on or near the surface if there is a good overnight freeze.There are two crusts of note in the upper snowpack. The first crust is down 20 to 30 cm and loose wet avalanches have recently slid on this interface. The deeper one down 60 to 95 cm has produced easy shears in test profiles. Avalanches on this interface are unlikely, but possible.

Avalanche Problems

Loose Wet

The sun is forecast to come out on Wednesday. Expect to see crusts that formed from overnight cooling break down quickly and the surface snow sluff in steep terrain.

Avoid sun exposed slopes when the solar radiation is strong, especially if snow is moist or wet.Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.Cornices become weak with daytime heating, travel early on exposed slopes.

Aspects: South East, South, South West, West.

Elevations: Treeline, Below Treeline.

Likelihood: Possible

Expected Size: 1 - 1.5
