Points saillants

The high alpine is where you will have the best chance of finding soft, dry snow, as well as heightened avalanche conditions on specific terrain features.

    Slabs may be possible to trigger at high elevations where dry snow has been loaded into leeward terrain features.

Avalanche Summary

There have been no recent reports of avalanches in the region. We suspect loose wet avalanches to have run during the rainstorm over the weekend. Avalanche activity is expected to decrease as temperatures cool.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).

Snowpack Summary

In the alpine, new snow from the weekend (we suspect up to 30 cm) sits over moist snow. Elsewhere, a crust develops over a rain-soaked snowpack.

Snow depths at treeline vary across the region. Prior to the rain, 140 cm was reported at Knuckles, 95 cm on the North Shore and 175 cm near Sky Pilot.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Start on smaller terrain features and gather information before committing to bigger terrain.
