Avalanche Forecast
Regions: Jasper.
Weather Forecast
Very warm temperatures are forecasted with freezing levels extending high into the alpine, 3,700m. Virtually no overnight recovery of the snowpack is expected once out of the valley bottom. An inversion may make for better AM travel in the valley bottom. Pack your sun block.
Snowpack Summary
Moist snow extends to treeline on all but the most Northerly slopes. On Southerly slopes this continues into the alpine. Persistent slabs can be found on most aspects at treeline and above. These have been reactive to large triggers like cornice failures. Below 1,900m the snowpack is going isothermal on a daily basis.
Avalanche Summary
The spring avalanche cycle will be in full swing over the next few days. Large and destructive avalanche can be expected from all elevations and running far into the valley bottom. Without an overnight freeze forecasted these events will start early, perhaps before midday. Explosive results on thursday produced numerous avalanche to size 2.5.
