Fresh snow provides fresh potential for building small wind slabs at higher elevations. Expect reactivity as new snow will sit over a crust. 

Summary

Confidence

Moderate - Forecast snowfall amounts are uncertain.

Weather Forecast

FRIDAY NIGHT: Mostly cloudy with isolated flurries. Moderate southwest winds and freezing levels around 1500 m.

SATURDAY: Mostly cloudy. Snow beginning early with up to 10 cm over the day. Freezing levels reach 2000 m. Moderate southerly winds. 

SUNDAY: 10-20 cm overnight. Mostly cloudy with 10-15 cm of snow during the day. Freezing levels around 2000 m. Strong southwest winds. 

MONDAY: Another 10-20 cm possible overnight. Clearing skies with light northeast winds. Freezing levels rise toward 2000 m.

Avalanche Summary

No new avalanches have been reported.

We would expect there to have been small releases of wet snow from steep terrain features as a result of the warm temperatures and rain on Tuesday and Wednesday. 

If you venture into the mountains, please share any observations on the Mountain Information Network

Snowpack Summary

New snow falls over a melt freeze crust on all aspects and elevations. Moist snow may be present at elevations below the freezing line. 

The upper snowpack consists of hard wind pressed surfaces and a series crusts. The mid and lower snowpack is considered well-settled and strong at this time. 

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.
  • Make observations and assess conditions continually as you travel.

Problems

Wind Slabs

An icon showing Wind Slabs

Reactive wind slabs are expected to form over a crust on north and east facing slopes. Look for wind loaded snow around ridgelines and rollovers.  

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood
