In sintesi

The snowpack is stabilizing after last week's storm, aided by Tuesday's cold temperatures and calm air. This trend should continue through the week, but with several buried weak layers persisting - keep your head up still. Merry Christmas everyone!

Problemi valanghivi

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–2.5
    The Dec 10 surface hoar and facets can be found 40-80 cm down in the deeper (western) parts of the forecast region. The layer is stabilizing, but continues to be a concern at at in treeline gladed areas.

  • Deep Persistent Slabs

    This problem dominates the central and eastern part of the forecast region and will continue to do so for some time. Continue to avoid large, open avalanche prone slopes at treeline and in the alpine as these cannot yet be trusted.

Weather Forecast

Christmas Eve looks like a nice night for Santa to fly. Clear skies with remnants of a full moon should help. Christmas day looks to have a mix of sun and clouds with some light flurries in the afternoon. Temperatures ranging from -10 to -18 across the region with light winds out of the west.

Snowpack Summary

The snowpack has doubled since Dec 10, and is slowly stabilizing after last week's storm cycle. Deeper snowpack areas continue to show the Dec 10 SH layer down 60-80 cm with hard, but sudden column test results. In shallow snowpack areas, the basal facets are producing easy collapse test results and should not be trusted.

Avalanche Summary

No new avalanches were observed today on Highway 93 North area.
