Central Sierra Nevada
Pericolo valanghe
In sintesi
Problematic avalanches are unlikely today for the vast majority of backcountry travelers. Any areas of unstable snow that exist will be isolated. Use backcountry travel techniques that will minimize the consequences of a small and unexpected avalanche.
Avalanche Discussion
While generally stable conditions exist, it is not inconceivable that a small lingering isolated pocket of unstable wind drifted snow could be encountered near ridgetops or in complex terrain. Problematic wet snow instability is unlikely today even though air temperatures will warm above freezing. Any areas of unstable snow today, wet or dry will be isolated so don't expect to see telltale signs of instability while approaching terrain. Use best practice terrain and travel management to minimize the consequences of a small unexpected avalanche.
As with any day in the backcountry LOW danger or not, travel with a plan that provides appropriate safety margins. Focus on terrain and conditions that match the skills and goals of your group. Move through terrain in ways that minimize exposure to avalanche hazards, exposing only one person at a time to avalanche terrain and regrouping in safe zones outside of avalanche terrain and runout zones.
Recent Observations:
* Signs of wind slab avalanches and cornice collapses that occurred on January 3rd and 4th remain visible in many areas.
* Variable snow surface conditions exist across the forecast area including firm ice, recent new snow over supportable crust, wind-packed surfaces, semi-supportable snow surfaces, and very isolated pockets of powder.
* Large cornices are common along ridgelines, often with deep fissures behind them.
