Summary
Weather Forecast
Snow should come in light flurries over the next few days with snowfall up to 15cm Monday afternoon. However, it will come with strong westerly winds up to 100 Km/h at ridgetops which will scour the landscape. Some of that snow may deposit in Saskatchewan while the rest will be on lee aspects making more windslabs in sheltered terrain features.
Snowpack Summary
Variable windslabs exist at ridgetop and exposed alpine/ treeline locations. Where the snow is deeper, a solid midpack bridges the weaker layers below. Surface conditions range from wind scoured rocky patches, to sustrugi, to hard slab, with the rare pocket of sheltered soft snow offering a few turns. Un-supportive facets dominate lower elevations.
Avalanche Summary
No new activity was noted on Sunday's patrol. It has been a while since any significant avalanche activity occurred. However, don't let your guard down since there is a lot of variability in the snowpack across the landscape.
Confidence
Forecast snowfall amounts are uncertain on Monday
