Regions

Dogtooth, East Purcell.

Expect the upper snowpack to weaken throughout the day with another day of warm temperatures and clear skies.

Confidence

Moderate

  • We are uncertain due to the timing or intensity of warming will affect the snowpack.

Avalanche Summary

Minor sluffing, pinwheeling, and small loose wet avalanches were reported on Wednesday.

Otherwise, no recent slab avalanches have been reported.

If you are heading into the backcountry, please share your observations with the Mountain Information Network.

Snowpack Summary

Either a thin surface crust or moist surface snow is expected by Friday morning, depending on the strength of the overnight freeze.

Continued above-freezing temperatures and sunny skies will likely create moist surfaces in terrain at all aspects and elevations by Friday afternoon.

A layer of surface hoar, buried in late January, is present in many areas approximately 5 to 15 cm below the surface, overlying a crust and/or faceted snow.

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

Weather Summary

Thursday Night
Clear skies. 20 km/h southwest ridgetop wind. Treeline temperature 3 °C. Freezing level 3300 m.

Friday
Sunny. 40 km/h southwest ridgetop wind. Treeline temperature 2 °C. Freezing level 2900 m.

Saturday
Mostly sunny. 1 to 5 cm of snow. 50 km/h southwest ridgetop wind. Treeline temperature -1 °C.

Sunday
Mix of sun and clouds. 3 to 10 cm of snow. 40 km/h west ridgetop wind. Treeline temperature -3 °C.

Terrain and Travel Advice

  • The more the snowpack warms up and weakens, the more conservative your terrain selection should be.
  • Avoid areas where the snow feels stiff and/or slabby.
  • Investigate the bond of the recent snow before committing to your line.
  • Avoid travelling on slopes below cornices.

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.
