Avalanche Forecast
Regions: Jasper.
Weather Forecast
For the Icefields, Friday night will have a little warm snow. Saturday - Sunday's freezing level will drop to 1500m and then 1100m on Monday. Temperatures will hover around -3 to -8 and light snow Saturday to Monday.
Snowpack Summary
Good skiing between 1900-2400m in sheltered areas. Icefields received 15cm of warm snow. This rests on a solid mid-pack that is bridging a weak base. The base is a combination of weak facets and depth hoar mixed around a Nov rain crust. Below tree line is a supportive 20cm melt freeze crust sitting above a weak facet layer to ground.
Avalanche Summary
No Patrol or public reports on Thursday or Friday. Wednesday's helicopter flight from Jasper to Sunwapta Resort to Maligne lake reported no new avalanches noted and visibility was good. Tuesday's patrol at Bald Hills also did not note any new avalanches. Despite natural activity subsiding forecasters have low confidence in the deep basal weakness.
Confidence
Due to the number of field observations on Saturday
