In sintesi

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    1–3
    Wind slabs from the last storm cycle remain a concern in select terrain, continued warm temps will encourage bonding to lower layers

  • Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    2–4
    The likelihood of triggering avalanches on this layer is decreasing but the consequence remains high.

  • Loose Wet

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible - Likely
    Dimensione
    1–3
    Use caution on all solar aspects, especially late in the day. Wet sluffs may "step down" to weaker layers and trigger a larger event.

Confidence

Poor - Due to the number and quality of field observations

Weather Forecast

A ridge of high pressure continues to dominate over southern BC for the next few days with no precipitation in sight for the forecast period. Warmer temperatures at upper elevations and associated valley fog is developing over the southern interior with freezing levels expected to go up to 3100 M. Valleys will remain cool with pooling of cold air, forecast winds at upper elevations are forecast to be light to moderate for the region.

Avalanche Summary

Wet sluffs and pin-wheeling have been reported on S facing alpine slopes above 1700 M with the recent temperature inversion. No other reports of recent avalanche activity have been received. This may speak more to the lack of reported observations rather than actual conditions. If you have information please feel free to contact us at: [email protected]

Snowpack Summary

Recent storm snow continues to settle and is gaining strength with time and warm temps. Wind slabs linger in lee terrain. Surface hoar buried in early November exists in the mid snowpack but due to a lack of data little is known about its reactivity and distribution. The October crust/facet interface buried near the base of the snowpack is still a concern. Surface hoar continues to develop at valley fog levels and in sheltered north aspects.
