Lo esencial

We're working from very few observations right now, but most of the region looks pretty wet and soggy.  The exception is the alpine where storm slabs and cornices are likely a real problem.  Please let us know what you're seeing on the MIN!

Problemas de aludes

  • Cornices

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    Cornices have likely formed on alpine ridgelines. Cornices are typically most prone to failure during times of transition. Now is one of those times as the snowpack adjusts to the most recent storm and we enter a colder period.

  • Storm Slabs

    • Alta montaña
    • Límite del bosque
    • Bajo el límite del bosque
    Probabilidad
    Possible
    Tamaño
    1–2
    If there's any good riding/travel to be had, it's going to be in the alpine. This is also where you're most likely to find storm and wind slabs slabs that may be sensitive to human triggering.

Confidence

Low - Due to the number of field observations

Weather Forecast

We are slowly transitioning towards a period of pronounced high pressure.  The forecast period is marked by cooler temps, very little precipitation and the potential for clear skies by the weekend.  THURSDAY NIGHT: Freezing level around 1200 m, light variable wind, no significant precipitation expected.FRIDAY: Overcast, freezing level around 1000 m, light southwest wind, a trace of snow possible. SATURDAY: A few clouds, freezing level around 750 m, light northeast wind, no significant precipitation expected.SUNDAY: A few clouds, freezing level around 800 m, light variable wind, no significant precipitation expected.

Avalanche Summary

No avalanches have been reported. Please submit any observations you have to the Mountain Information Network here.

Snowpack Summary

Monday and Tuesday's storm produced over 200 mm of precipitation that mostly fell as rain. Winds were extreme out of the south/southwest. Cornices likely formed on many ridgelines. Alpine areas near Squamish have the most snow, with around 70 cm of settled snow on the ground. In the alpine, there may be a crust lower in the snowpack. It is thought that there is insufficient snow for avalanches below 1500 m.
