Regions

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

Start on small, mellow slopes and watch for signs of instability before approaching steeper or larger slopes.

Snowfall will vary. If you find 40 cm+ of fresh, increase danger by one step.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

Looking forward

With two days of stormy weather, we expect that human triggered avalanches in the recent snow are likely.

Monday

Around Whistler, a couple of small, rider triggered avalanches were reported in extreme alpine terrain, along with a few large, explosives triggered cornice falls.

Sunday

A skier was caught in a small slab: MIN.
Explosives triggered a few size 1 to 1.5 wind slabs and cornices.

Snowpack Summary

Another 20 to 30 cm of new snow is expected by the end of the day on Wednesday. Extreme southwest wind through the night, and moderate to strong wind through the day is expected to form deeper, more reactive deposits in leeward terrain.

This should all add up to 40 to 60 cm of recent storm snow over a widespread, thick and hard crust below about 2000 m, and old wind-affected snow at upper elevations.

Deeper in the snowpack, older weak layers currently buried 70–100+ cm have likely gained strength, and are not considered a problem at this time.

Weather Summary

Tuesday Night
Cloudy. 10 to 15 cm of snow, possibly 25 cm or more north and west of pemberton. 65-80 km/h southwest ridgetop wind, decreasing by early morning. Treeline temperature -3 °C. Freezing level 1200 m.

Wednesday
Cloudy. 10 to 15 cm of snow, possibly 20 cm or more north and west of pemberton. 30-50 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Thursday
Mostly cloudy. 3 to 10 cm of snow. 30 km/h southwest ridgetop wind. Treeline temperature -7 °C.

Friday
Mostly cloudy. 2 to 5 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -4 °C.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be especially cautious as you transition into wind-affected terrain.
  • Avoid avalanche terrain during periods of heavy loading from new snow, wind, or rain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
