Lo esencial

The strong westerly flow remains in place for at least another day.  Ridgetop winds were consistently strong to extreme Tuesday and there is till some redistribution of storm snow occurring - windslabs continue to build and become more cohesive.

Problemas de aludes

  • Wind Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    2–5
    Wind slabs continuing to thicken and become more reactive to a skiers weight - on some steep lee features windslabs are in excess of 50cm thick.

  • Persistent Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible - Likely
    Tamaño
    2–6
    A long term concern this winter - weak base exists in man areas up to 2400 meters in elevation or at the upper limit of treeline so carefully consider the presence of this problem!.

Good

Weather Forecast

Mix of sun/cloud with no new precipitation.  Westerly flow remaining strong to extreme with gusts to 85km/h predicted.

Avalanche Summary

One Size 1 loose dry reported in the Buller chutes.  One Size 3 SSL off of east side of Snow Peak probably occurred in previous 24 hours - ran to middle of runout zone taking out "usual" uptrack.  Numerous Size 2 SSL on NE asp Mt Sir Douglas and at Burstall Pass.  FL generally 1m deep with bed surface a combination of ground and old snow layers.

Snowpack Summary

Wind transport along ridgetops has been reduced due to the fact that most loose snow that was available for wind transport has been moved around - but some redistribution is till occurring.  A perfect combo of new snow, wind and mild temps has created new windslabs with variable thickness depending upon location and amount of snow in fetch zones.  In the Burstall area they varied from  20-50cm thick.
