Avalanche problems should be limited to elevations that received new snow. Sunshine and warming will destabilize this snow on Thursday. Keep your guard up to prevent a small avalanche from ruining your day.

Avalanche Summary

No recent notable avalanches have been reported.

Snowpack Summary

After a period of light rain, new snow has begun to accumulate on the surface. Up to 15 cm of new snow can be expected in the alpine and the depth and reactivity of new storm slabs will likely increase with elevation. The new snow is accumulating on a variable surface of wet snow and crust.Below the surface, the overall snowpack is well settled and strong. New cornices formed and old ones grew more overhanging with the snowfall at the end of last week. Cornices become more unstable as the temperature rises and as they are loaded by rain and new snow.

Problems

Storm Slabs

A final pulse of snow and wind has been building up new storm slabs in the alpine. Aside from slab problems, expect small loose wet avalanches to release either naturally or with human triggering on steeper, sun-exposed slopes.

Be careful around wind loaded pockets near ridge crests and roll-overs.Use caution in lee areas in the alpine. New snow and wind may have formed touchy slabs.Avoid exposure to terrain traps where the consequences of a small avalanche could be serious.

Aspects: All aspects.
