Regions

Flathead, Lizard, Moyie, St. Mary.

Avalanche danger is expected to increase through the day on Wednesday as skies clear and freezing levels rise rapidly.

Confidence

Moderate

  • We are uncertain due to rapidly changing freezing levels.

Avalanche Summary

A natural avalanche cycle occurred over the weekend with numerous slab avalanches up to size 2, primarily on north though east aspects at treeline and above. These all appeared to fail on the late January surface hoar/crust/facet layer outlined in the snowpack summary.

Since the natural avalanche cycle, several small (size 1 to 1.5) human-triggered avalanches have been reported on a variety of aspects at treeline and above.

Snowpack Summary

Refrozen and crusty surfaces are likely on steep, south-facing slopes and across most below-treeline terrain on Wednesday morning. The upper snowpack is likely to become moist throughout the day, at all elevations, due to rapidly rising freezing levels.

Approximately 20 to 50 cm of recent snow has buried a widespread melt–freeze crust, which may have surface hoar on top and faceted snow above and/or below.

The mid- and lower snowpack is well-settled, with no significant concerns.

Weather Summary

Tuesday Night
Partly cloudy. 50 km/h west ridgetop wind. Treeline temperature -1 °C. Freezing level rising overnight to 2600 m.

Wednesday
Mix of sun and clouds. 50 km/h west ridgetop wind. Treeline temperature 1 °C. Freezing level 3100 m.

Thursday
Mostly sunny. 50 km/h west ridgetop wind. Treeline temperature 3 °C. Freezing level 3400 m.

Friday
Mostly sunny. 40 km/h southwest ridgetop wind. Treeline temperature 4 °C. Freezing level 3200 m.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Remote triggering is a concern; avoid terrain where triggering overhead slopes is possible.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Avoid travelling on slopes below cornices.

Problems

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.

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.
