Avalanche Forecast
Regions: Jasper.
Weather Forecast
Pacific air will continue to override cooler air in the valleys producing a temperature inversion through to Tuesday. Winds should remain light from the SW through Monday until late in the day Tuesday when they will increase and potentially bring some light flurries or rain. 10mm of precipitation with moderate SW winds expected to arrive mid-week.
Snowpack Summary
10-15cm of recent snow has blown into thin slabs TL and above. Although the mid-pack Dec 15 layer of concern has not been reactive in test profiles (nor has it been tied to any recent avalanche activity in the Jasper area), we are still monitoring this interface closely. There is still a distinct crust (Nov 17) in the lower third of the snowpack.
Avalanche Summary
Another pulse of natural loose dry point releases was observed today in the Columbia Icefield area and in the Maligne Valley. These slides were mostly out of steep, solar facing terrain. Field teams did not observe any new slab avalanches avalanches.
