Use caution at all elevations. storm slabs may still be reactive to rider traffic.

Weather Forecast

Friday night: light flurries with freezing levels around 1200m. Moderate wind shifting from southwest to northwest.

Saturday: light flurries ending around noon. light northwest winds. Freezing levels rising to 2000m.

Sunday: light flurries in the evening. Moderate southwest winds and freezing levels rising to 2000m.

Monday: stormy weather with 10 mm of precipitation and moderate southwest winds. Freezing level around 1500 m.

Avalanche Summary

We suspect natural avalanches could occur on Friday. If you observe any avalanche activity in the backcountry please consider filling out a Mountain Information Network report.

Snowpack Summary

Wind slab will likely be found on north and east aspects.

Up to 60cm sits above a thick and supportive crust that extends to mountain top. In the far north and east of the forecast region a layer of facets and surface hoar could be found above this crust.

The middle and base of the snowpack are well settled and strong. In isolated areas north in the region, a layer of faceted grains on a crust may be found 150-200 cm deep; however, observations suggest that this layer has become unreactive. 

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.

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.
