Wind slabs may remain triggerable on isolated lee slopes.
Use normal caution and check all steep open slopes for slabs before committing to them.
Recent strong wind has created widespread wind effect on snow surfaces. Small wind slabs may linger on any aspect and steep open slope, including openings below treeline, although the highest likelyhood is near ridgetops.
On Thursday, explosive control near Pine Pass produced several cornice falls and entrained loose snow in the size 1.5 to 2.5 range.
Looking forward, triggering avalanches is unlikely, except for on steep wind-loaded slopes in isolated areas.
If you do observe an avalanche please submit a MIN report.
Up to 5 cm of snow may have fallen by Monday morning. This snow is falling on extensive wind effect on all aspects, including lower elevations below treeline in some areas. Wind slabs have developed on leeward slopes and crossloaded features, which are likely stubborn to trigger by now.
On some ridgetops, the wind stripped the snow in wind-exposed terrain down to the early-February melt-freeze crust. In wind-sheltered terrain, around 30 to 60 cm of snow overlies this crust. It seems well-bonded and is not considered a problem at this time.
The remainder of the snowpack is consolidated with no layers of concern.
