In sintesi

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!

Problemi valanghivi

  • Cornices

    • Alta quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    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 quota
    • Limite del bosco
    • Sotto il limite del bosco
    Probabilità
    Possible
    Dimensione
    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

The storm has passed, and now we’re 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.WEDNESDAY NIGHT: Freezing level holding around 1200 m, light variable wind, trace of precipitation possible.  THURSDAY: Scattered cloud cover, freezing level around 1200 m, light variable wind, no significant precipitation expected.FRIDAY: Scattered cloud cover, freezing level around 1300 m, light variable wind, no significant precipitation expected.SATURDAY: Scattered cloud cover, freezing level around 900 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.
