In sintesi

Clear skies, light winds, and mild temps are forecasted through the weekend. Pay attention to rising temperatures on solar aspects as freezing levels may rise as high as 2500 m on Friday. Ice climbers should pick their routes accordingly.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    2–3
    Recent strong s.w. winds have created windslabs up to a metre thick on lee slopes in the alpine (primarily N- E aspects). Although these slabs are starting to settle out with warm temps it is still possible for a skier to trigger these slabs.

  • Persistent Slabs

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

    In many areas east of the divide where the snow is shallower the midpack overrides a layer of weak basal facets. Be extra cautious of thin snowpack areas where the chance of triggering this layer is highest.
