Problèmes avalancheux

  • Wind Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Possible
    Taille
    1–2

    Possibility new snow with varied consistency depending on elevation. Slabs may be limited to TL elevations but depends on condition of old surface, which is quite varied across the region.

  • Deep Persistent Slabs

    • Alpin
    • Limite forestière
    • Sous la limite forestière
    Probabilité
    Unlikely - Possible
    Taille
    2–3.5

    This problem will require a large trigger, thin spots, increased loading or rapid day time warming.

Weather Forecast

A NW flow to the upper atmosphere with cold air to the NE will keep temps cool despite the opportunity for solar input. Upslope conditions and zonal flow over the mountain will yield light precipitation. Clearing slightly on Wed with a shallow ridge then back to a W flow for Thursday.

Snowpack Summary

Moist new snow, more in the front ranges on a supportive melt freeze crust exists on all aspects, BTL and solar aspects at TL and Alp elevations. Snowpack has yet to have a deep melt freeze cycle and basil weakness is still a looming hazard sensitive to large loads like cornices.

Avalanche Summary

No new alligators observed or reported.

Confidence

Due to the number of field observations
