Regions

South Coast, Powell River, Tantalus, North Shore, Sasquatch, Sky Pilot, Tetrahedron, Harrison-Fraser.

New snow and wind loading has formed reactive storm slabs.

Make conservative choices and be very wary of exposure to overhead hazards, especially when the sun is out.

Confidence

Moderate

  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.
  • We are uncertain about how quickly the snowpack will recover and gain strength.

Avalanche Summary

On Sunday, several storm slabs up to size 1.5 were reported.

Natural and human triggered avalanches remain likely on Tuesday, especially on sun-facing slopes.

Snowpack Summary

Up to 40 cm of recent storm snow rests on a variety of underlying surfaces, including wind-affected snow in the alpine, facets on north-facing aspects, and sun-affected snow on south-facing aspects. In areas where facets or crusts are present, expect the potential for a poor bond at the storm snow interface.

A crust from early February, buried 20 to 60 cm deep, appears to be well bonded to the overlying snow.

The remainder of the snowpack is generally well bonded.

Snowpack depths at treeline range from 90 to 170 cm, tapering rapidly below treeline, particularly on south-facing aspects.

Terrain and Travel Advice

  • Use increased caution at all elevations. Storm snow is forming touchy slabs.
  • Avoid sun-exposed slopes, especially if the snow surface is moist or wet.
  • As the storm slab problem worsens, the easy solution is to choose more conservative terrain.

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.

Loose Wet

Loose Wet avalanches are the release of wet unconsolidated snow or slush. These avalanches typically occur within layers of wet snow near the surface of the snowpack, but they may quickly gouge into lower snowpack layers. Like Loose Dry Avalanches, they start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-wet avalanches include point-release avalanches or sluffs. Loose Wet avalanches can trigger slab avalanches that break into deeper snow layers.
