A strong high pressure to the south of us has a "blocking pattern" set up over the Rockies. Clear and dry is the game right now.

Avalanche Summary

Nothing new today

Snowpack Summary

A partial definition of low: "small avalanches in isolated areas or extreme terrain". At the moment these small avalanches are almost certainly going to start within the surface wind slab layers near alpine ridges. Regardless of the layer responsible, in the wrong terrain (steep and unsupported) there is still avalanche hazard. Lots of surface facetting due to the cold. Treeline elevation windslabs are starting to break down from this facetting.

Problems

Deep Persistent Slabs

Hard slabs overlying facets is the main concern. Be cautious in gullies, unsupported areas or steeper terrain.

Watch for whumpfing, hollow sounds, and shooting cracks.Carefully evaluate terrain features by digging and testing on adjacent, safe slopes.

Aspects: North, North East, East, South East, South.

Elevations: Alpine.
