In sintesi

A significant storm rolled into the region Tuesday afternoon bringing strong winds and moderate to heavy snowfalls. This will lead to a spike in hazard levels on Wednesday. Conservative terrain choices are in order.

Problemi valanghivi

  • Wind Slabs

    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Very Likely

    Previously formed wind slabs are now hidden by the new snow. An avalanche triggered in the newly formed storm slabs could step down to the early November facets and cause a large avalanche.

  • Loose Dry

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità

Snowpack Summary

The storm arrived this afternoon bringing moderate flurries and strong winds. Storm slab development is on going in the Alpine and at Treeline, adding to existing wind slabs at these elevations. Lee and cross-loaded features are places to watch for these various slabs. Loose dry avalanches are also expected in steep terrain on all aspects.
