The Bottom Line: Warm temperatures and sunshine on Tuesday may allow for another round of wet avalanche activity in isolated areas. Watch for unstable snow on steep, sun-exposed slopes.
Snow and Avalanche Discussion
On Monday, mountain weather stations in adjacent areas recorded temperatures in the mid-50s at 5000ft. Wet loose avalanche activity occurred on southerly slopes at mid and upper elevations over the past 3 days. A cooling trend will begin to lock up the snowpack. Avalanche concerns will diminish when snow surfaces are frozen and hard but may turn on again during peak heating hours.
Avalanche Problems
Loose Wet
High freezing levels and intense sunshine continue to create the potential for loose wet avalanches. These avalanches will primarily be a concern in the afternoon hours on steep sun-exposed slopes at upper elevations. Watch for roller balls, pinwheels, and for the surface crust to melt and become unsupportable. These are good indications snow surfaces are weakening and wet avalanches may follow. Be aware of terrain traps like gullies, creeks, and cliffs that can increase the consequences of even small avalanches. Avoid steep slopes with wet unconsolidated snow surfaces.
