Avalanche Summary
A few small wind slabs were reported yesterday.
We expect avalanche activity to increase in frequency and size through the weekend.
Snowpack Summary
Up to 50 cm of new snow overlies a surface hoar layer, particularly around treeline elevations and below. In sun-exposed terrain, surface hoar may rest atop a thin crust, while elsewhere it sits atop a mix of old wind-affected surfaces and weak, faceted snow.
A widespread crust with facets and/or surface hoar, buried in mid-January, is approximately 30 to 70 cm below the surface.
The mid and lower snowpack is well-settled.

Terrain and Travel Advice
- Storm slabs in motion may step down to deeper layers resulting in large avalanches.
- Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
- Avoid avalanche terrain during periods of heavy snowfall.
Problems
Storm Slabs
New snow and wind have formed reactive slabs over a weak layer of surface hoar. Storm slabs could step down to a crust/surface hoar layer buried in mid January.
