Avalanche Summary
No new avalanches were reported on Wednesday.
Natural and human-triggered avalanches are likely on Friday and through the weekend.
Snowpack Summary
15 to 30 cm of snow is forecast by Friday afternoon. The new snow will likely have a poor bond to the old snow surfaces. These consist of a thick melt-freeze crust on sun-exposed slopes, large surface hoar and/or facets on shaded slopes, and wind-affected surfaces in exposed terrain.
The upper snowpack may contain one or more layers of surface hoar buried sometime in January. These layers are not currently a problem but may wake up with the upcoming storm loading.
The mid and lower snowpack remains generally well-settled and strong, with no current concerns or significant instability noted.
