In sintesi

Strong to extreme winds are expected to continue - if forecasted snowfall amounts are greater than currently forecasted we can look forward to a spike in Avalanche Danger into the CONSIDERABLE range. Overall ski conditions remain suspect!

Problemi valanghivi

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely
    Dimensione
    1–3
    The likelihood of even a small avalanche stepping down into the deeper weak base is something for all to keep in mind.

  • Storm Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Likely - Very Likely
    Dimensione
    1–4
    Any more new snow coupled with winds will only serve to make surface slabs more "touchy".

Confidence

Fair - Forecast snowfall amounts are uncertain on Wednesday

Weather Forecast

Snowfall expected by Tuesday AM did not materialize and forecasted amounts are now less than 10cm over the next 24 hours. A strong westerly flow is expected to continue and rapid redistribution of storm snow onto lee aspects is expected. Even small amounts of new snow coupled with winds action will make recently formed slabs more "touchy" so give careful consideration to the presence of new slabs in the upper elevation zones.

Avalanche Summary

No new observed or reported.

Snowpack Summary

Only trace amounts of new snow over past 24 hours. Windward features are stripped completely bare by intense westerly flow. Some thin storm slabs formed in previous 48-72 hours may be sensitive to triggering in specific features such as immediate lees and cross-loaded gullies.
