New snow may not be bonding to the cold, wind-affected surfaces below. As snow accumulates slab and loose avalanches may become more likely.

Confidence

High

Avalanche Summary

No new avalanches have been reported since the weekend.

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

Snowpack Summary

Fresh snowfall is burying snow surfaces previously impacted by northerly winds and cold temperatures. The recent cold and clear weather has likely led to widespread facet and surface hoar development which may prolong the bonding of new snow to the underlying surfaces.

The mid and lower snowpack consists of various old crusts and is generally well-settled and well-bonded.

Weather Summary

Tuesday Night

Cloudy with 5 to 10 cm of snow, southwest alpine winds 10 to 30 km/h, treeline temperature -7 °C.

Wednesday

Cloudy with 5 to 10 cm of snow, north alpine winds 0 to 20 km/h, treeline temperature -10 °C.

Thursday

Mostly cloudy with no precipitation, variable winds 0 to 20 km/h, treeline temperature -12 °C.

Friday

Cloudy with up to 10 cm of snow, southwest alpine winds 20 to 50 km/h, treeline temperature -2 °C.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Watch for fresh storm slabs building throughout the day.

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.
