With forecasted values of snow still unreliable with the incoming storm, effects on the current snowpack is still uncertain. Any significant accumulation will increase the avalanche hazard.
Summary
Weather Forecast
A low pressure system is approaching, bringing welcomed warm temperatures and precipitation. Valley bottom temps are expected to reach above freezing through the week. As of now snow values are uncertain, precipe is expected to start Monday evening and continue till Thursday.
Snowpack Summary
A verity of surface slabs ranging from good supportive skiing to impenetrable hard slab sit over a very faceted mid pack. This slab/facet interface is the primary concern in the snowpack and has been the cause of many recent avalanches. As the incoming low moves in bringing precipitation, any significant load will dramatically affect the hazard.
Avalanche Summary
No avalanche activity reported or observed in Little Yoho today, but we have minimal observations from this area.
Confidence
Problems
Persistent Slabs
Facets buried on Dec 19 are down 50-70 cm in some locations. This is a concern wherever a more cohesive slab of snow sits on top of this weakness. Wind loaded areas seem to be the primary concern.
Aspects: All aspects.
Elevations: Alpine, Treeline.
