Regions

Sea To Sky, South Coast, Homathko, Powell River, Tantalus, North Shore, Sasquatch, Sasquatch, Sky Pilot, Tetrahedron, Coquihalla, Harrison-Fraser, Manning, Skagit.

Continuously assess conditions as you gain elevation. Winter conditions persist at higher elevations.

New storm slabs could form throughout the day where precipitation falls as snow.

Confidence

Moderate

Avalanche Summary

No new avalanches have been reported in the past few days.

If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring.

Snowpack Summary

10 to 25 cm of new snow may accumulate over a crust on all aspects at higher elevations. The largest deposits will be found on north and east aspects. This new snow may not bond well to the underlying crust. Below treeline rain will keep the snow surface wet or moist where snow still exists. Most below treeline terrain is already snow free.

Weather Summary

Wednesday Night

Cloudy with trace to 2 cm of new snow at treeline and above. 10 to 30 km/h southwest alpine wind. Freezing level falling to 1300 m.

Thursday

Cloudy with 5 to 15 cm of new snow in the alpine. 10 to 20 km/h south alpine wind.  Freezing level rising to 1700 m.

Friday

Cloudy with 5 to 10 cm of new snow in high alpine terrain. 5 to 15 km/h variable alpine wind. Freezing level rising to 2000 m.

Saturday

Cloudy with 5 to 15 cm of new snow in the alpine. 25 to 50 km/h south alpine wind. Freezing level rising to 1800 m.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Watch for fresh storm slabs building throughout the day.
  • Closely monitor how the new snow is bonding to the crust.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Expect shallow snow cover that barely covers ground roughness.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
