Regions
Kananaskis.
The natural activity has slowed, but skier triggering is a REAL possibility in most skiable terrain. Gone are the days of ambitious lines. Conservative skiing is the name of the game right now. Inversions are forecasted for Mon/Tues. MM
Confidence
Fair - Intensity of incoming weather is uncertain on Monday
Weather Forecast
High pressure over the area until Sunday night, precip will be limited. Temps will start to climb tomorrow afternoon in the alpine, yet fall in the valley bottoms. As the next system moves in, we can expect to see another wave of temperature inversions. Winds will be from the North with moderate to strong speeds (300m).
Avalanche Summary
Na, size 2, slab, south face Rimwall (west wind pass area) , 2400m
Snowpack Summary
HST settling to 45cm @ 2100m, Below 2100m, surface hoar and facets make up the midpack, above 2100m, a thinner layer of facets are on top of a settled midpack. Nov crust down 120. HS 124 See result of compression test here
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
