Avalanche Forecast
Regions: Jasper.
Weather Forecast
Temperatures and winds remain arctic like. Expect light N winds, no new snow, and clear skies for the next three days.
Snowpack Summary
Surface snow is facetting with the arctic temps and loosing internal cohesion. Southerly slopes in the alpine have been stripped by previous SW winds with hard slab on lee features. At treeline, the snow is faceted that is barely supportive and weak in shallow areas.
Avalanche Summary
Good visibility Jan 2 highway patrol. Several loose dry avalanches up to size 2 on steep alpine rocky terrain all aspects. 4 slabs up to size 2.5 noted on Mt. Cirrus above polar circus ice climb. They did not crest the wall but critical for ice climbers to take these into consideration. 1 icefall on Athabasca glacier did not initiate a slab below.
Confidence
The weather pattern is stable
