Summary
Confidence
Avalanche Summary
No new avalanches were observed or reported on Thursday
Snowpack Summary
2-15 cm of snow forecasted by Friday AM will cover hard surface crusts on all aspects except for north facing alpine slopes above ~2300 m. Be on the lookout for small, fresh windslabs in alpine lee areas where recent winds will have blown the new snow into deeper pockets.
In the mid-pack, the Feb 3 persistent layer (crust/facet layer) remains a feature in the snowpack but has been unreactive with recent colder temperatures. This layer is a greater concern in thin snowpack areas
Weather Summary
An upslope flow overnight Thursday could bring up to 15 cm by mid morning on Friday. Amounts will vary with as little as a trace in some areas. Expect deeper amounts in eastern areas. Freezing levels will be 1500- 2000m.
Saturday and Sunday will be warmer with freezing levels 2000 - 2500m and continued flurries/showers.

Terrain and Travel Advice
