Summary

Confidence

Poor - Due to the number of field observations

Weather Forecast

Mainly sunny and cool, with some cloud later Monday afternoon. A series of weak storm systems will push into the interior and bring light snowfall amounts. Freezing levels near 1000 m with ridgetop winds  moderate from the S-SE.

Avalanche Summary

There are no new avalanche reports from the region.

Snowpack Summary

Around 10-20cm of recent snow sits on a newly formed rain crust. At alpine elevations, recent storm slabs and wind slabs may still be sensitive to triggers like the weight of a person. Deeper in the snowpack, weaknesses such as loose sugary facets and crusts exist in some locations. A recent snowpack test from the Hankin-Evelyn area produced easy/moderate pop results down 30 cm on one of three buried crusts.

Problems

Wind Slabs

An icon showing Wind Slabs
Wind slabs may be found behind terrain breaks like ridges and ribs. In certain areas, a slab could fail on a deeply buried weakness, creating a surprisingly large avalanche.
Avoid areas with a thin or variable snowpack.>Choose well supported terrain without convexities.>Use ridges or ribs to avoid wind loaded and cross loaded slopes.>
