Lo esencial

Snow and wind will arrive late tomorrow afternoon. Expect slabs to build quickly due to the warming air temps and relatively warm snow temps. Last night helped to refresh the skiing with 10-15cm of new snow.

Problemas de aludes

  • Wind Slabs

    These are lingering at upper treeline and alpine elevations. Steep terrain is still concerning.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad

    Tamaño

    These remain on the list of problems to look for because of the variability within the snowpack. Probing and digging is the best tool to find and assess this layer.

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely

    The winds will keep these slabs limited to immediate lee areas. This includes cross loaded gullies. 

Snowpack Summary

10-15 cm's of new snow fell last night. The winds that accompanied the snow have created new storm slabs at treeline and alpine elevations. These slabs are concentrated on east to south aspects and near ridges. The underlying surface for this new snow will be a variety of crusts on low elevations, crusts on south aspects, and windslabs in the alpine. At all elevations, the concerning layers from last week have healed up well making for a relatively strong snowpack.

High

Weather Forecast

A few flurries are expected tomorrow. With any luck, we'll get 6cm or so out of them. The temps will be relatively warm and max out at -2 in the low alpine. The winds will be mostly light tonight and tomorrow, but there are gusts up to 50km/hr expected for both days.

Avalanche Summary

No new avalanches noted today.
