Avalanche Forecast
Regions: Jasper.
Weather Forecast
Cool air from the north will remain over the area on Tuesday with the possibility of up to 5cm of fresh show. The greatest snowfall is forecast to occur to the east and at upper elevations. Moderate ridge top winds from the N and NW will redistribute the snow onto southerly and easterly facing slopes. Temps at treeline will approach zero in mid PM.
Snowpack Summary
A spring temperature crust up to 15cm thick can be found near the top of the snowpack. This crust has been found as high as 2600m in the Icefields area. In places it is buried under several inches of new snow. Wind slabs can be found at upper elevations on most aspects due to varied wind direction patterns. Cornices are large and dropping.
Avalanche Summary
No new avalanches were reported today. One avalanche was reported late Friday above the icefalls on the Athabasca glacier which originated from steep, cross loaded gullies in the high alpine. Cooler temperatures and no solar radiation due to cloud cover has reduced natural activity in the last few days.
Confidence
Timing, track, or intensity of incoming weather system is uncertain on Tuesday
