Regions

South Coast Inland, Brandywine, Garibaldi, Spearhead, Birkenhead, Duffey, South Chilcotin, Stein, Taseko.

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

New wind slabs could form where precipitation falls as snow.

Confidence

Moderate

Avalanche Summary

One natural and one human triggered cornice fall has been reported in the past couple 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

Storm snow will continue to accumulate at higher elevations. This snow may overlie a crust that it might not bond well too. Below treeline rain will keep the surface wet or moist where snow still exists. Most below treeline terrain is already snow free.

Weather Summary

Thursday Night

Cloudy with up to 5 cm of new snow at treeline and above. 10 to 25 km/h southeast alpine wind.  Freezing level around 1600 m.

Friday

Mostly cloudy with up to 5 cm of new snow at treeline and above. 15 to 25 km/h south alpine wind. Freezing level rising to 1800 m.

Saturday

Cloudy with 5 to 10 cm of new snow at treeline and above. 20 to 40 km/h south alpine wind. Freezing level around 1700 m.

Sunday

Cloudy with up to 15 cm of new snow. 40 to 60 km/h south alpine wind. Freezing level around 1500 m.

Terrain and Travel Advice

  • Be carefull around freshly wind loaded features.
  • Expect shallow snow cover that barely covers ground roughness.
  • Minimize your exposure time below cornices.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
  • Make observations and assess conditions continually as you travel.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind 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.
