Avalanche Forecast
Regions: Jasper.
Weather Forecast
Freezing level 1500m and light flurries next few days. Temperatures will be seasonal with relatively good overnight freeze. Winds expected to be light SW.
Snowpack Summary
Expect wind slabs in lee and cross-loaded terrain above 2000m. The persistent slab is down 40-70cm and is easily triggered in the Whistler/Portal areas even on low angle slopes but is stubborn in the Icefields. Lower elevation snowpack is facetted and weak.
Avalanche Summary
No field patrol Monday. Previous reports of numerous remotely triggered avalanches to size 2 on slope angles as little as 15 deg around Marmot Pass along with widespread whumphing and cracking. Whumphing and cracking also noted in the Maligne area. In contrast, no reports of any propagations in the Icefields area.
