Regions

Northwest Coastal, Northwest Inland, Boundary, Kitimat, Nass, Rupert, Seven Sisters, Shames, Stewart, Howson, Kispiox, Ningunsaw.

Sun can quickly change snow conditions. Avoid steep slopes if the snow is moist, and stay well clear of cornices, which may weaken and threaten slopes below.

Confidence

Moderate

We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

A wet loose avalanche cycle has occurred over the last couple of days during periods of warming and sun at lower elevations and south-facing slopes at higher elevations.

Snowpack Summary

Crusty surfaces are present across most terrain, except in high alpine north-facing areas, where dry, wintry snow can still be found, and isolated wind slabs may linger. On solar aspects and lower elevations, surface crusts are expected to soften with daytime warming and solar input.

Several persistent weak layers are buried up to 250 cm deep. While triggering these layers is becoming unlikely, they present a low-probability, high-consequence problem. A cornice fall (large load) may be enough to trigger this slab.

Weather Summary

Friday Night
Partly cloudy. 2 to 3 mm of precipitation as snow or rain at treeline in the North of the region, no precipitation forecast for the South. 10 km/h southeast ridgetop wind. Treeline temperature 1 °C. Freezing level 1400 m.

Saturday
Mostly sunny. 20 km/h east ridgetop wind. Treeline temperature 0 °C. Freezing level 1300 m.

Sunday
Mostly sunny. 2 mm of precipitation as snow or rain at treeline. 20 km/h south ridgetop wind. Treeline temperature 1 °C. Freezing level 1300 m.

Monday
Mostly cloudy. 3 to 10 cm of snow. 40 km/h southwest ridgetop wind. Treeline temperature -1 °C. Freezing level 1000 m.

Terrain and Travel Advice

A moist or wet snow surface, pinwheeling, and natural avalanches are all indicators of a weakening snowpack.
Be aware of the potential for large, destructive avalanches due to deeply buried weak layers.
Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.

Problems

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.

Persistent Slabs

Persistent Slab avalanches are the release of a cohesive layer of snow (a slab) in the middle to upper snowpack, when the bond to an underlying persistent weak layer breaks. Persistent layers include: surface hoar, depth hoar, near-surface facets, or faceted snow. Persistent weak layers can continue to produce avalanches for days, weeks or even months, making them especially dangerous and tricky. As additional snow and wind events build a thicker slab on top of the persistent weak layer, this avalanche problem may develop into a Deep Persistent Slab.
