Points saillants

Where dry snow exists, fresh, reactive storm slabs could be found.

Treat the danger as CONSIDERABLE if you're seeing more than 15 cm of new snow.

    Heavy rain saturating the upper snowpack will create wet loose avalanches in steep terrain.

    Where precipitation falls as snow, fresh storm slabs will be forming. Expect deeper, more reactive deposits in wind-loaded terrain.

Avalanche Summary

No recent avalanche activity has been reported.

Heavy rain on Tuesday could destabilize the upper snowpack, creating wet loose avalanches on steep slopes.

If you head out, please consider posting your observations to the Mountain Information Network.

Snowpack Summary

Heavy rain will impact most North Shore mountains on Tuesday. Heavy snowfall could occur on some of the highest peaks.

The mid and lower snowpack are generally strong and well-bonded.

Typical treeline snow depths range from 100 to 150 cm, and thin quickly below treeline, especially on south-facing slopes.

Confidence

Moderate

  • We are uncertain if precipitation will fall as rain or snow.

Terrain and Travel Advice

  • Loose avalanches may start small, but they can grow and push you into dangerous terrain.
  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
