Regions: East Island, North Island, South Island, Vancouver Island, West Island.

With few field observations over the weekend, we are uncertain but remain skeptical of the bond of the recent storm snow. Take a conservative approach and gather information as you travel.

Confidence

Low

Avalanche Summary

No new avalanches have been reported since Friday and Saturday, when natural and skier controlled storm slabs up to size 1.5 were reported on west to northeast aspects near treeline.

Snowpack Summary

20 to 50 cm of snow fell over the weekend. Near ridgetops, recent moderate to strong southwest wind has likely loaded the recent snow into leeward terrain features.

This recent snow is not expected to bond well to underlying surfaces including a hard crust in most areas, or facets and/or surface hoar on high north aspects.

The mid and lower snowpack is well-settled and dense with no other layers of concern.

Weather Summary

Sunday night

Mostly cloudy with 1 to 5 cm of snow. 20 to 40 km/h southwest ridgetop wind. Treeline temperature -10 °C.

Monday

Mostly cloudy with 1 to 5 cm of snow in most areas, up to 10 cm on the east coast. 30 to 50 km/h southeast ridgetop wind. Treeline temperature -10 °C.

Tuesday

Mostly cloudy with 1 to 5 cm of snow. 30 to 50 km/h southeast ridgetop wind. Treeline temperature -10 °C.

Wednesday

A mix of sun and cloud. 20 to 40 km/h southeast ridgetop wind. Treeline temperature -7 °C.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Make observations and continually assess conditions as you travel.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
  • Use small, low consequence slopes to test the bond of the new snow.

Avalanche Problems

Storm Slabs

Recent snow is not expected to bond well to underlying layers. Storm slabs likely remain triggerable by riders. The most likely places to trigger an avalanche are in wind-loaded lee terrain features just below ridgetops and convex rolls.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5
