Avalanche Summary
No new avalanches have been reported in the last 2 days. A natural avalanche cycle is expected during Saturdays storm.
Snowpack Summary
The incoming storm snow amounts are expected to average around 30 cm and in the most western reaches of the region exceed 50 cm. This new snow will accumulate on various surfaces, including surface hoar in wind-sheltered terrain at treeline and below, thin melt-freeze crust on south-facing alpine slopes, and old storm snow at higher elevations. Above 1200 m, a crust is now estimated to be down 35 to 65 cm. The mid and lower snowpack is well-settled with no layers of concern.
