Avalanche hazard has increased from the past few days due to sustained north and easterly winds.

Weather Forecast

Arctic high pressure in full effect over British Columbia bringing a day time high today of -20 with beautiful clear skies. Northerly winds are forecast to ease to 20km/h. This ridge has no intention of moving for the near future. Temperatures will warm up slightly on Thursday and into the weekend.

Snowpack Summary

5-10cm of soft snow overlies hard snow surfaces of sun crust on steep solar aspects and wind slab at higher elevations. This new snow has seen some wind affect and has bonded poorly to the layers beneath. A new surface hoar layer is down 5cm at lower elevations. The mid pack is well settled but cold weather has begun faceting the snowpack.

Avalanche Summary

No new avalanches observed yesterday.

Wind Slabs

Expect to see some wind loading on south and west aspects, not typical of this area. The new snow has not bonded well to the old surfaces and was reactive early this week to rider traffic. People could expect the same but with a stiffer windslab.

Be cautious as you transition into wind affected terrain.Caution in lee and cross-loaded terrain near ridge crests.

Aspects: All aspects.

Likelihood: Possible
