Kernpunkte

We're working from very few observations. While dirt has reappeared at lower elevations, it is very much winter in the alpine where cornices and wind slabs may remain problematic this weekend. Please let us know what you're seeing on the MIN!

Lawinenprobleme

  • Wind Slabs

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    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 wind slabs that may be sensitive to human triggering.

  • Cornices

    • Hochgebirge
    • Waldgrenze
    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Possible
    Größe
    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 we enter a colder period.

Confidence

Low - Due to the number of field observations

Weather Forecast

We are transitioning into a period of pronounced high pressure. The forecast period is marked by cooler temps, clear skies and no significant precipitation, even in the extended forecast.FRIDAY NIGHT: Freezing level around 1100 m, light southerly wind, a trace of snow possible. SATURDAY: A few clouds, freezing level around 1200 m, light northeast wind, no significant precipitation expected.SUNDAY: Clear skies, freezing level around 800 m, light northeast wind, no significant precipitation expected.MONDAY: Clear skies, freezing level around 800 m, light east 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.
