Observations are limited and early-season hazards are abundant.

Take a conservative approach and watch for signs of instability as you transition into wind-affected terrain.

No new avalanches have been reported in the past few days, but field observations remain very limited.

Light snowfall will accumulate atop wind-affected surfaces in open areas and 20 to 30 cm of settling snow in sheltered areas.

A weak layer consisting of a crust, facets, or surface hoar is buried 30 to 70 cm below the surface. Observations are limited at this time of year and the geographical extent of this weak layer is still uncertain.

Treeline snowpack depth is around 120 to 160 cm.
