Lo esencial

The recent snow is hiding the windslabs that formed earlier in the week.  We are not into spring stability right now!  Best skiing will be on sheltered N aspects.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Windslabs in alpine areas along ridgelines and crossloaded features. Watch for these at the entrances to runs.

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Unlikely - Possible
    Tamaño
    1–3
    Overhead cornices loom along ridgelines. As daytime temps warm up, these will become weak and have potential to collapse.

Avalanche Summary

Over the past 36hrs there have been a few sz 2 slides out of N and E aspects in alpine areas.  There are mainly failing down 20-30cm and 30-50m wide. 

Snowpack Summary

5-10cm new snow fell across the region overnight with very little wind affect.  This new snow now blankets the previous windslabs that formed earlier in the week.  These windslabs are easy to find in alpine terrain and are 20-40cm thick.  What natural avalanche activity we did see on Friday showed these windslabs failing mainly on N and E aspects in steeper terrain or in unsupported features.  Field test were showing an easy to moderate sheer at the interface of the windslabs with the underlying snow.  Be heads up in steeper areas  and choose supported terrain. Light snow was starting as we left.  The best skiing will be on N aspects due to crusts on solar aspects.
