In sintesi

Several days without an overnight freeze followed by cooling temps and incoming precipitation will quickly change our avalanche problem from loose wet to windslab. Pay close attention to signs of solar warming on Friday and Saturday and consider avoiding lee terrain as the next storm arrives on Sunday.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

No new avalanches observed on Wednesday and no field work conducted on Thursday during warming event.

Snowpack Summary

Alpine/Treeline: Surface snow is moist. 5-20 cm of wind slab exists in lee features. In sheltered areas, 10 cm of snow overlies a 2-15cm crust. 10-15 cm of facets sits below this layer. The lower snowpack is well settled with multiple crusts. Total snow height is 160-200cm.

Below Treeline: The upper 10 cm are moist. The mid-pack is a series of crusts and facets. Lower snowpack is melt forms to ground. Total height of snow is 40-110cm.

Terrain and Travel Advice

  • A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
  • Approach lee and cross-loaded slopes with caution.
