Lo esencial

Another spring-like day will bring little change to conditions. Snow surfaces may take longer to soften Wednesday with strong winds and cloudy skies continuing through the morning. You may be able to trigger small wet avalanches on the steepest, sunniest slopes late in the day.

    You’re most likely to find wet snow in the afternoon on SW aspects around rocks and cliffs where the snowpack is shallower. A quick way to check for loose wet avalanches is by using your boot. When you sink into wet snow past your ankle start anticipating loose wet avalanches on nearby slopes. While these slides should remain small and localized to just a few features, don’t let them catch you by surprise and push you into a terrain trap. Even a small avalanche can hurt you if it carries you over a cliff or buries you deeply in a gully.

Avalanche Discussion

From January 30 to February 2, storms deposited 8-12 inches of snow over variable surfaces in the East South Zone. Strong ridgeline winds redistributed this last snowfall into dense slabs, scoured westerly aspects, and created stiff, wind-pressed surfaces. Since then, warm, sunny days and cool nights allowed the snowpack to resume another prolonged diurnal melt-freeze cycle reminiscent of the springtime. Avalanche concerns are now limited anywhere you find firm and frozen snow surfaces. As the snowpack thaws throughout the day, small wet loose activity and cornice fall may continue on E-S-W aspects. A wet avalanche cycle has largely run its course, but consider avoiding consequential terrain late in the day where you find wet, slushy snow. 

Eastern portions of the zone received little snow during the last storm, and thick icy crusts exist on the surface maintaining challenging travel conditions. There was a significant loss in overall snow height in January, and many ridgelines, southern aspects, and low elevation slopes melted out to bare ground. Several creeks reopened as well, and many snow bridges fractured or collapsed. Shallowly buried obstacles are additional hazards to manage. Conditions don't look to change anytime soon with dry, sunny weather in the forecast for the rest of the week.
