Highway 93 will remain closed into Thursday due to driving conditions. The recent storm brought a significant amount of snow. Allow it to settle and stabilize.
Weather Forecast
The weather will be cold and stable next few days. No new significant snow expected. Winds will be light to moderate out of the West.
Snowpack Summary
The recent storm brought 60cm. Snow depths vary between 70 to 140 cm in the Icefields. Generally unsupportive below treeline and improving at you approach TL and above. Moderate to strong ridge top winds have created soft slabs particularly on lee aspects. Threshold values have been reached on some slopes and snow remains available for transport.
Avalanche Summary
Explosive work on Parkers slabs had one shallow size 2.5 slab and a couple smaller releases. Some natural avalanches up to size 3 within last 24 hours were noted in the alpine mainly on lee steep slopes.
Confidence
The weather pattern is stable on Thursday
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
Loose Dry
Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
