Due to the depth of the weak layers, trigger points are isolated but the consequence would be high. Shallow areas, rocky areas, and areas with Variable snowpack depth should be avoided. This problem may also exist Below Treeline in the Front Ranges.
Deep persistent slabs are best managed by:
Cornices are best managed by:
A stationary Low equals Status Quo. Temperatures have cooled since midweek, and will fluctuate with daytime warming between -13 and -3 . Light winds and a mix of sun and cloud will dominate the forecast period, other than overcast skies late Saturday. A light Upslope event with overcast skies and flurries may arrive late Sunday or Monday.
A few Cm of recent snowfall is well bonded to harder, wind affected snow below. A thin, breakable rain crust on the surface extends up to 1900m, with Moist snow below. Faceted layers in the mid and lower snowpack remain a concern, particularly in shallow snowpack areas where facetting is more pronounced and triggering is more likely.
A few small avalanches Size 1 were noted from extreme terrain Below Treeline on Thursday and Friday. No large avalanches have been observed since a natural Deep Persistent Slab avalanche a week ago. This initiated in a shallow area in a wind-affected Alpine basin, when a small windslab from above stepped down to a faceted crust near ground.
