Avalanche Forecast

Fair - Forecast snowfall amounts are uncertain on Tuesday

The winds are expected to build from the southwest on Monday, and moderate precipitation should start to accumulate snow by late afternoon. A trailing cold front is forecast for Tuesday. Snowfall amounts are un-certain and will depend on how much moisture is in the area when the cooler air arrives. Strong southwest winds and rising freezing levels are forecast for Wednesday. Models are showing the snow confined to near coastal areas, with only light amounts in the interior and South Rockies.

Skiers remotely triggered a size 2.0 slide from 10 metres away, that was 60 cm deep, 70 metres wide, and 75 metres in length. Natural avalanche activity reported today was limited to a natural wind slab release size 2.5 from a North-East aspect. We continue to get reports of old activity that occurred during the recent storm.

Tests in Hartly Creek on Saturday showed easy results down 20 cm on a layer of stellar crystals. Height of snow in the Koko Claims area is 120 cm at 200 metres. The mid-december surface hoar is down about 30 cm. The mid-pack is generally well consolidated, and there is a 20 cm layer of 4F facets and depth hoar at the ground. The surface hoar is producing easy to moderate shear test results.
