In sintesi

Good quality turns can still be found in sheltered areas below tree line that were not hit by Tuesday's wind event.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1.5–2.5

    Previous strong southwesterly winds have resulted in wind slab formation in open terrain features at all elevations. Be most wary of where slab has built over shallow areas, on unsupported slopes, and on steeper solar aspects.

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2.5

    Use caution around thin to thick areas. Keep an eye out for surface hoar in isolated sheltered locations below treeline.

Weather Forecast

A high pressure system will continue to provide mostly clear skies, light  NW winds, no precip and temperatures trending to below seasonal normals.

Snowpack Summary

There are no significant changes in the snowpack over the past 3 days. Previous winds have stripped snow from exposed terrain and resulted in wind slabs and wind affected snow in open terrain below treeline, at treeline and in the alpine. The midpack is supportive. Surface hoar is found down 40cm to 80cm in isolated sheltered locations.

Avalanche Summary

No new avalanches observed today (limited observations) or reported.
