Heads up as most groups are recreating in one drainage, watch for groups above and below you! Early season hazards are lurking below the snow surface, ski / ride cautiously.
Weather Forecast
Cloudy with sunny periods today and a dusting of new snow. Alpine high of -6 with a rising freezing level to 1400m. Winds will be moderate today gusting to strong from the south. Tomorrow we're expecting 15-20cm with increasing winds and mild temps.
Snowpack Summary
10cm overnight, 35cm now covering the Nov 9 interface, 30-40cm over the Halloween crust at tree line. The crust sits on 30-50cm of rounded grains and mixed forms which seems to be bonding well for the time being. No significant instabilities in the snowpack currently, except for a slowly building storm slab on the surface.
Avalanche Summary
Eleven slab avalanches were recorded yesterday in the Highway corridor, up to size 2.5. These slides started in very steep terrain, mostly dry and made it to the run out zone.
Confidence
Due to the number and quality of field observations
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.
