Continue to monitor slab development at treeline and expect reactive slabs in the alpine.
As you approach treeline, expect to encounter slab development. Take the time to investigate what the recent snow is sitting on and how it is bonding. Some of these slabs may have suncrust, facets, or surface hoar (Jan 30th) as the bed surface.
Sunday will have a trace of snow in the AM then clearing skies, continued moderate gusting strong W winds, and freezing levels to 15000m. Up to 10cm Monday, with temperatures in the alpine slightly inverted which should drop by the afternoon. Alpine winds will spike to strong by Monday afternoon.
Moderate winds continue to redistribute the 20-50 cm that has accumulated over the Jan 30 crust, surface hoar and wind effect. Hard slabs can be found in alpine. While slab development at treeline is only starting, these are more likely to overlay a sun crust or surface hoar or facets. Shallow snowpack areas remain weak and faceted.
No avalanche observations from Little Yoho on Saturday.
