Strong east winds are reverse-loading the recent storm snow in exposed areas.
Slab avalanches remain reactive to riders.

Avalanche Summary
Several Na and human-triggered size 2 avalanches have been reported since Friday. The avalanches are releasing on surface hoar below the storm snow. This MIN from the Pass Lake area is a good example of how touchy this problem is.
Snowpack Summary
Exposed areas are heavily wind-affected. Up to 50 cm of new snow has fallen since Wednesday. The new snow is bonding poorly to old snow surfaces, which include a melt-freeze crust on sun-exposed slopes, large surface hoar and/or facets on shaded slopes, and wind-affected snow in exposed terrain at ridgelines.
A widespread crust with facets and/or surface hoar, buried in mid-January, is approximately 60 to 120 cm below the surface.
The lower snowpack is well-settled.

Terrain and Travel Advice
- Expect slab conditions to change drastically as you move into wind-exposed terrain.
- Make observations and continually assess conditions as you travel.
- Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
- Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
