Avalanche Forecast
Regions: Jasper.
Weather Forecast
Flurries are expected overnight but with little accumulation resulting as a cold arctic front starts to sweep SW from the icy NE. Clearing expected Sunday and into next week with sunshine and cold nights.
Snowpack Summary
Available snow has been redistributed by strong, variable direction winds. In sheltered Treeline locations, the weak midpack layers are reactive down 50cm. Where snow remains in the Alpine, new wind slabs are reactive to triggering from additional load or solar, and wind-stiffened snow at Treeline is transmitting collapses large distances.
Avalanche Summary
Isolated windslab avalanches were observed today in the Icefields area and loose dry avalanches to size 2 were observed in the Tonquin valley. East, South, and North aspects have formed windslabs and large cornices that have failed in the last 48 hrs in the north portion of the forecast zone.
Confidence
Due to the number of field observations
