Avalanche Summary

No recent avalanche activity has been observed.

If you head into the backcountry, please consider submitting a MIN report.

Snowpack Summary

New snow low-density snow has buried various previously wind-affected snow surfaces at treeline and above.

In sheltered terrain, the new snow has buried faceted snow, which, may prolong the bonding of new snow to the underlying surfaces.

Roughly 100 cm of recent snow sits atop a crust with a generally well-settled and stable lower snowpack.

With recent snowfall lower elevation areas may now be at the threshold for avalanches.

Weather Summary

Wednesday Night

Mostly clear with no precipitation, northwest alpine winds 10 to 30 km/h, treeline temperature -12 °C.

Thursday

Mostly cloudy with no precipitation, southwest alpine winds 10 to 30 km/h, treeline temperature -8 °C.

Friday

Cloudy with 2 to 5 cm of snow, southwest alpine winds 30 to 50 km/h, treeline temperature -1 °C.

Saturday

Cloudy with trace snow and rain, southwest alpine winds 10 to 30 km/h, treeline temperature 0 °C, freezing levels 1800 m.

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.
  • Closely monitor how the new snow is bonding to the old surface.
  • Pay attention to the wind, once it starts to blow fresh sensitive wind slabs are likely to form.

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.
