Weather Forecast
The forecast temperature going into next week will be another warming trend with freezing levels rising to Treeline elevation by Tuesday and into Wednesday. Accompanying this Southwest flow will bring light precipitation and strong winds in the Alpine.
Snowpack Summary
Warmer daytime temperatures this weekend are promoting settlement of the upper snowpack and creating more of a slab over the basal facets especially in wind affected areas. The lower half of the snowpack is poorly structured, with facets (Nov 24th) below the recent storm snow, thin crusts (Nov 6th) below this, and then depth hoar near the ground.
Avalanche Summary
Skier triggering is still high in likelihood particularly coupled with the recent daytime warming. Two size 2 skier accidentals were triggered this afternoon just outside ski area boundaries around Sunshine and Lake Louise back country. This reaffirms the weak basal layers persist and remain prone to human triggering so very little has changed.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Tuesday
