Avalanche Forecast
Regions: Jasper.
Weather Forecast
Cooling temperatures over the next 48 hours with the chance of snow flurries. The SW flow will become more westerly with the freezing levels dropping to the valley bottom overnight and not reaching the treeline during the day. Cooler temperatures are forecast for the Icefields area where the greater amounts of snow can also be expected at elevation
Snowpack Summary
At treeline and below warming temperatures and rain has increasing the temperature of the snowpack. Moist snow in the upper pack can be anticipated. Surface crusts will form when temps drop. Solar facing slopes close to treeline may have buried crusts with slab snow above. Deeply buried weaknesses near ground. Windslabs in the alpine.
Avalanche Summary
Slab and point release avalanches observed Tuesday up to size 2.5 from treeline and below. All events are stepping to ground. Most are being triggered by warm temperatures and rain. One or two of these events started above treeline in areas where strong and extreme winds, from the SW, are developing wind slabs. These to are steeping down to ground.
Confidence
Freezing levels are uncertain on Wednesday
