Weather Forecast
Up to 10cm of snow is forecast to fall over the next 24hrs with generally light winds. Temperatures will be around -10C with generally cloudy skies.
Avalanche Summary
A sz 2 dry loose slide was observed on the SW aspect of Mt Murray initiating in 40+ degree terrain at 2800m and ran down to 2200m. This slide was observed from a distance so details area little scant. Also 2 skiers ski cut a sz 1.5 slide around 30m wide in what they described as the "DogLeg" couloir on a N aspect of heros knob.
Snowpack Summary
Isolated windslabs that are skier triggerable should be expected along ridgelines in alpine areas. These slabs are not widespread but there is a distinct drummy feel in some steeper areas that should keep you on your toes. Also, windslabs were observed from recent down flow winds in alpine terrain. Otherwise, the warming temps are slowing the facetting process but overall, the snowpack is composed of mainly facetted grains with some more dense snow forming the mid pack. Thin areas are where a skier may be able to trigger the basal weaknesses but we have not seen any activity on this layer in some time.
