Good skiing can be found at tree line and below. Careful evaluation of wind slabs is essential before adventuring in the alpine.
Summary
Confidence
Moderate - Due to the number of field observations
Weather Forecast
The cold continues with a slight daytime warming. Tuesday and Wednesday are forecast for daytime highs of -15c with overnight lows of -27c. Skies should be a mix of sun and cloud with light wind from the North on both days. No snow forecast for the near future.
Avalanche Summary
One size 2 slab on an East aspect on an alpine feature on Mt. Murray.One size 2.5 slab on a NE aspect starting in the alpine in the Black Prince zone.One size 2 slab on a NE aspect starting in the alpine was observed in the Gypsum Creek zone.
Snowpack Summary
35-45cm of storm snow overlies a strong mid snowpack. This storm snow is low density at tree line and below. In the alpine, this storm snow has either turned into a wind slab or is loose and dry; it will be important to determine this before adventuring into the alpine. The buried sun crust on solar aspects down around 60cm is still a concern with this new load as well as the isolated January 17 SH also down around 60cm around 2200m. The basal facets are down 80-100cm and should still be on everyone's radar as any avalanche triggered in the upper snow pack has the potential to trigger this lower weakness.
