In sintesi

Alpine winds will pick up again tonight. If the spike lasts for awhile, expect new windslabs and possibly a jump to considerable in the alpine. Be prepared for a quick change.

Problemi valanghivi

  • Wind Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2
    Recent winds led to wind slab development in the Alpine and just into Treeline. Watch for unusual loading patterns due to northerly winds.

  • Deep Persistent Slabs

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Unlikely - Possible
    Dimensione
    1–2.5
    A recent avalanche on this layer suggests it is on the verge of waking up and becoming a problem again. New wind loading may put enough weight/stress on the snowpack to cause an avalanche.

Weather Forecast

Another chilly morning is expected. Lows will be around -15 to -20. Daytime highs will be around -7. No snow to speak of, alpine winds will pick up during the day and expect light cloud cover for most of the day.

Snowpack Summary

No major change in the region's snowpack overnight. We did receive a hint of snow, but in the grand scheme of things, 4cm is irrelevant. What is relevant though is the spike in alpine winds from a few days ago. The alpine has isolated, new windslabs on north to south aspects. The cold north wind caused some reverse loading. The slabs tend to be near ridges, and not too big. Treeline snow is generally facetted and weak with a hint of the windslabs from the last week. These slabs are less reactive as the bond gets better with the layers below. Valley bottom snow is very weak. Breaking a new trail is a lot of work!
