Unstable air has brought convective flurries to the forecasting region over the last couple of days.
Expect bouts of both cloudy skies with intense snowfall and poor visibility, as well as sunny skies that can yield moist snow very quickly.
While a generally deeper, and thereby stronger, snowpack exists in the Yoho zone, pay attention to shallower areas where the potential to trigger the deeper weak layers is more likely.
In the deeper snowpack areas of this region the Deep Persistent Problem is becoming less of a concern, but continue to pay attention to this layer in areas where the snowpack is shallower (such as moraines or wind scoured areas).
No new avalanches were observed or reported Saturday.
5-10 cm of snow fell March 24 that buried temperature crusts to 1600m, sun crusts to ridgetop on solar aspects and facets on shaded slopes.
The middle of the snowpack holds several crust and facet layers.
The base of the snowpack is weak, unconsolidated depth hoar in almost all areas.
Cornice failures occur regularly at this point of the season.
Cloudy skies will start to clear into Sunday morning with the potential for a few flurries giving way to the potential for sunshine in the afternoon. Cloud will re-build overnight Sunday, again with the potential for flurries. Freezing levels will reach 1500m Sunday with further cooling for Monday. Alpine winds will remain light Sunday but may just touch into moderate on Monday.
