Choose conservative terrain

Storm slabs are expected to increase in size and likelihood throughout the day

If you observe natural avalanches or more than 30 cm of new snow treat danger as high

Confidence

Moderate

  • We are confident about the likelihood of avalanche activity, what is less certain are their possible size.

Avalanche Summary

Over the past couple days, several natural storm/wind slabs (size 1.5–2.5) were observed on north and east alpine slopes.

Fast-running sluffing was also reported from steep, sheltered slopes throughout the region, both from natural and human triggers.

Snowpack Summary

An additional 30 cm of storm snow could accumulate by the end of the day on Friday. This new snow will be accompanied by moderate southerly wind, forming deeper deposits on north aspects at treeline and above.

70 to 110 cm of settling snow sits over a prominent crust formed in mid-December that extends up to 2300 m.  Where this crust is thick and supportive, it effectively caps a few weak layers from December and November, making them difficult to trigger. These layers, now over 150 cm deep, may still be a concern in the high alpine where the crust is thin or nonexistent.

Weather Summary

Thursday Night

Cloudy. 5 to 10 cm of snow. 25 to 40 km/h south ridgetop wind. Treeline temperature -6 °C.

Friday

Cloudy. 5 to 20 cm of snow. 20 to 30 km/h southwest ridgetop wind. Treeline temperature -6 °C.

Saturday

Mix of sun and clouds. 3 to 5 cm of snow. 20 km/h northwest ridgetop wind. Treeline temperature -16 °C.

Sunday

Mix of sun and clouds. 1 cm of snow. 20 km/h west ridgetop wind. Treeline temperature -15 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Use ridges or ribs to avoid areas of wind-loaded snow.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
  • Start with conservative terrain and watch for signs of instability.

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.
