Avalanche Forecast
Regions: Jasper.
Weather Forecast
SIGNIFICANT WARMING TREND over the next 48 hours with freezing levels rising to 3500m and staying there (i.e. poor overnight freeze) until Friday. Over the weekend we expect cooler temps and a shift to a North Easterly flow which has the potential to bring up to 10mm of precipitation falling as rain below 2300m.Â
Snowpack Summary
There is rain crust from the valley bottom to 2,350m and a sun crust into Alpine on solar aspects. We expect a widespread natural avalanche cycle over the next 48 hours as temperatures rise and the crusts deteriorate. This has the potential to produce large, full depth avalanches on all aspects.
Avalanche Summary
Several loose wet size 2 noted on Mt sask at 2100-2500m stopping before the river. One size 2 loose wet off boundary peak. Cornice failure peak across sunwapta station E aspect initiated nothing. Isolated loose wet activity in the Maligne Valley on solar aspects.
Confidence
Timing or intensity of solar radiation is uncertain
