Regions: Bull, Elkford West, Flathead, Lizard, Lizard-Flathead, South Rockies.

Slightly warmer temperatures and new snow may increase the reactivity of persistent slabs

Avalanches are possible where the upper snowpack whumpfs, cracks or feels slabby under your feet

Confidence

Moderate

Avalanche Summary

On Wednesday no new avalanches were reported.

Rider triggering remains possible where a stiffer slab exists above the late January buried weak layers.

If you head into the backcountry consider submitting a MIN post!

Snowpack Summary

30 to 70 cm of faceted snow overlies a weak layer from late January. This layer consists of a crust on sun exposed slopes and a layer of surface hoar on all other aspects. Exposed terrain in the alpine and treeline is variably wind-affected creating a stiffer slab above the weak layer. In turn, the stiffer slab may be easier to trigger under the weight of a human.

The mid and lower snowpack is generally well settled.

Weather Summary

Thursday Night

Cloudy with isolated flurries. 10 km/h east ridgetop wind. Treeline temperature -12 °C.

Friday

Cloudy with new snow up to 5 cm. 10 to 20 km/h east ridgetop wind. Treeline temperature -7 °C.

Saturday

Cloudy with sunny periods. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -11 °C.

Sunday

Cloudy with flurries up to 5 cm. 10 km/h southwest ridgetop wind. Treeline temperature -9 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Approach steep and open slopes at and below treeline cautiously, as buried surface hoar may exist.
  • Be careful as you transition into wind-affected terrain.

Avalanche Problems

Persistent Slabs

Human triggered avalanches are possible where a slab has formed above a weak layer of surface hoar, facets, and/or crust buried at the end of January about 30 to 70 cm deep.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1.5 - 2.5
