Kananaskis

Though Spring has not yet arrived to our snowpack, the intense April sun is having an effect - pay attention to rapidly changing conditions on sunny days. Good skiing is being found on sheltered northerly aspects.

Moderate - Timing or intensity of solar radiation is uncertain

Tuesday looks to be mostly sunny with freezing levels climbing to at least 1800m. It will likely feel very warm in the sun. Winds will be moderate from the West. Conditions continue to warm up through Wednesday and Thursday.

Solar triggered pin-wheeling and sluffing occurred on steep solar aspects, but generally not much mass was involved.

Up to 10cm of new snow at Treeline in the past 24hrs, with much less at lower elevations. This snow was turning moist on solar aspects by late morning, and by tomorrow morning should be frozen into another in a series of previously formed crusts on these solar slopes. On polar aspects between 20 and 30cm of dry snow is currently on the surface, but buried crusts are found at lower elevations. Wind slabs are widespread in the Alpine on all aspects, but are more isolated at Treeline. Not much natural avalanche activity has occurred with these wind slabs, but many areas like ripe for human-triggering. As previously reported the mid-pack remains dense and strong, but the basal layers are very weak consisting of anywhere between 50 and 100cm of facets sitting on the ground. Forecasters still have low confidence for traveling in large Alpine terrain, unless there has been widespread previous avalanching.
