In sintesi

Avalanche danger is low anywhere a hard melt-freeze crust exists on or near the snow surface. Assess for isolated wind slabs in the high alpine for areas that received some new snow.

    Small wind slabs may form at high elevations near mountain tops for areas that received recent snow.

Snowpack Summary

Anywhere from a dusting to 10 cm of snow overlies a hard melt-freeze crust. Strong northerly wind may create small, isolated wind slabs near mountain tops.

The remainder of the snowpack is strong with numerous thick melt-freeze crusts.

Avalanche Summary

Explosives triggered a very large wet slab avalanche near Pine Pass during warm weather on Tuesday.

Cooler weather has decreased the likelihood of avalanches. Assess for small wind slabs in steep terrain if you find new snow in your local area.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Terrain and Travel Advice

  • Periods of low danger may be a good time to increase your exposure.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Carefully evaluate steep lines for wind slabs.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
