Avalanche Summary

Numerous wet loose avalanches were reported during the sunny period earlier this week.

We expect that in localized areas that receive more than 20 cm of new snow rider triggerable storm slabs could be found.

Snowpack Summary

Around 10 cm of new snow will overlie a crust on solar aspects and at lower elevations. on High north facing terrain this new snow will overlie surface hoar.

30-50 cm down there is a old sun crust on solar aspects and a layer of surface hoar (3-5 mm) on isolated shady and sheltered slopes.

Another layer of surface hoar or sun crust, aspect dependent, that was formed in mid-February can be found down 80 to 110 cm.

The lower snowpack includes a layer of weak sugary facets near the ground. These facets are slowly gaining strength and no recent avalanches have been reported on this layer. However, we continue to track the layer and watch for any signs of it becoming active.
