Continually assess the snowpack for signs of instability with dynamic weather conditions.
Triggering of deep weak layers remains possible in terrain with shallow, variable snowpacks. Where supportive to riders, a melt-freeze crust may be providing a bridging effect, making it more difficult to trigger deeper layers.
No recent avalanche activity has been reported in the region.

Wet flurries and high freezing levels produced moist surface snow up to 2000 m on Friday. Above 0 C temperatures were reported above 2100 m. As temperatures cool a crust will form. Isolated flurries through Saturday are not expected to accumulate beyond 5 cm.
A widespread melt-freeze crust is buried 50-90 cm. This crust ranges in thickness from 1 cm at higher elevations to 20 cm thick at lower elevations. Below the crust, the mid-snowpack is settled and consolidated.
A crust and facet layer is down 70-150 cm. Below the crust, the basal snowpack is weak and faceted. Treeline snow depths average 150-200 cm.
