Avalanche Summary

A couple of naturally triggered storm slab avalanches were reported over the weekend on various aspects in high alpine terrain.

A naturally triggered size 2.5 persistent slab avalanche was reported on an east aspect in the alpine on Saturday. The slab failed on a crust below recent storm snow. It was in steep, rocky, wind-affected terrain below an alpine ridgetop.

Snowpack Summary

Overnight snowfall may bury a variety of surfaces, including hard crusts, moist snow, or dry, powder snow.

The new snow may form cohesive, surface slabs in areas affected by wind or late in the day, resulting from daytime warming.

A series of crusts exist in the upper snowpack.
