Regions

Sea To Sky, Brandywine, Garibaldi, Homathko, Spearhead, Tantalus.

New snow and wind loading have formed touchy storm slabs, especially on north through east facing slopes.

Stick to non-avalanche terrain or small features with limited consequence.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

On Tuesday, several natural (size 1-2) and human-triggered (up to size 2) slab avalanches were reported.

A fatal, human-triggered (size 3.5) happened on Tuesday in the adjacent forecast region near Anniversary glacier. This occurred on a wind loaded northeast slope in the alpine.

On Monday, the region saw a widespread natural avalanche cycle up to (size 3.5), this activity occurred during the storm.

Snowpack Summary

Strong winds and new snow on Thursday will likely form fresh and reactive storm slabs at upper elevations. This adds to the 60 cm of storm snow that fell earlier this week, which sits on a variety of old snow surfaces, including stiff wind slab, facets, and crust.

The early February crust/facet layer is down approximately 8 to 100 cm.

Another widespread crust and facet layer from late January is buried 120 to 160 cm deep.

The mid and lower snowpack is well settled and strong.

Weather Summary

Wednesday Night
Cloudy. 10 to 15 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Thursday
Cloudy. 10 to 15 cm of snow. 60 km/h southwest ridgetop wind. Treeline temperature -3 °C. Freezing level 1200 m.

Friday
Mostly cloudy. 5 to 15 cm of snow. 50 km/h west ridgetop wind. Treeline temperature -4 °C.

Saturday
Mostly sunny. 30 km/h west ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
  • Strong wind is building wind slabs farther downslope than usual.

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.
