Kernpunkte

Avalanche danger is expected to remain low for the North Shore mountains, but wet avalanches may still be problematic in the higher elevation alpine terrain of the Squamish area.

    • Unterhalb der Waldgrenze
    Wahrscheinlichkeit
    Unlikely - Possible
    Größe
    1–2
    Up to 50 mm of rain has saturated the entire snowpack of the North Shore mountains. The same is likely true of higher elevation terrain in the Squamish area, but very isolated pockets of wet avalanches may remain problematic there.

Confidence

Low - Due to the number of field observations

Weather Forecast

A wet weekend is in store for the South Coast. The freezing level is expected to fluctuate through the weekend, look for rain transitioning to snow mid-day Saturday. On Monday the freezing level may creep above the mountains of the South Coast. Stay tuned for more details.

Snowpack Summary

On Friday January 5th the rain began to fall in earnest. As of 17:00 on Friday evening the Strachan Precip Station at 1220 m had recorded 53 mm of total rain fall. This rain has saturated the entire snowpack on all but the highest elevation slopes. 50 to 100 cm below the surface there are a few prominent melt-freeze crusts that were buried mid-December. Snowpack investigation Friday afternoon revealed rain is not pooling at these crusts with any significance.The rain has reduced the snowpack depth at 1000 m to about 140 cm and many early season hazards are still present at lower elevations.
