Use caution at higher elevations where recent precipitation could have fallen as snow and formed thin wind slabs.

Summary

Confidence

Moderate -

Weather Forecast

Tuesday night: Freezing levels around 1400m with light to moderate north winds. Light flurries bringing rain and trace amounts of snow at higher elevations. 

Wednesday: Mainly cloudy with sunny breaks. Light to moderate north winds with freezing levels reaching 1500m. 

Thursday: Cloudy with flurries bringing trace amounts of new snow. Moderate northwest winds and freezing levels rising to 1400m.

Friday: flurries bringing trace amounts of new snow with moderate to strong northwest winds. Freezing levels around 1300m.

Avalanche Summary

On Monday a few size one natural wet loose avalanches were observed on steep south and east facing terrain at 1200m.

No new avalanches were reported on Sunday. On Saturday, a natural rockfall-triggered loose wet avalanche was reported from a south-facing cliff band. Glide cracks were also reported to be opening up. 

Snowpack Summary

Monday's snowfall buries a widespread surface crust which exists on all aspects and at all elevations. Thin new wind slabs may have formed in exposed terrain at higher elevations. 

The late-January melt-freeze crust is now down around 40 cm and is reported to be knife hard and up to 30 cm thick. This crust extends to at least the top of treeline and is generally well bonded to the adjacent snow. 

The middle and lower snowpack are considered well settled and strong.

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Problems

Wind Slabs

An icon showing Wind Slabs

Thin new wind slabs may have formed on Monday. These could be more reactive than normal given the hard crust they are sitting on. 

Aspects: All aspects.

Elevations: Alpine.
