Lo esencial

Brittle ice continues to provide lacerations and stitches for climbers. Carefully evaluate fragile freestanding pillars, detached features and hanging hazards.

    Although this layer has been dormant, it is still a concern and is widespread between 2100-2600m.

  • Loose Dry

    Cold temps have weakened the snow clinging to steep terrain, and as a result shedding and sluffing should be expected.

Weather Forecast

Temperatures beginning to warm, albeit slowly. Increased clouds and alpine temperatures near -20. No precip expected for Saturday and trace amounts Sunday. Shifting winds, light to near moderate speeds from the North to the West and Southwest will still keep wind chill values high for the weekend.

Snowpack Summary

Cold temps are promoting facetting in the snowpack breaking down surface tension and support, especially below 2100ms. Where HS is shallow, expect to be on the ground. Deeper snowpack areas have faceted top down to the Nov12 crust (down 45 to 90cm). This continues to provide support and, for those braving the cold, good turns in sheltered areas. 

Avalanche Summary

No new avalanches observed or reported.

Confidence

Timing, track, or intensity of incoming weather system is uncertain on Monday
