Highway 93 remains closed until better visibility occurs for avalanche control in the high alpine. Check for updates on Alberta road reports. Pending avalanche control results, there is a high confidence that the road will open by 1700 hours.
Weather Forecast
A ridge of high pressure will be in the forecast area for Monday with few clouds, light Southerly winds and colder temperatures with high diurnal swings.
Snowpack Summary
On Saturday strong Southwest winds redistributed up to 50cm of storm snow onto lee aspects making another slab over the previous hard slab surfaces. On Sunday night, another 34cm of snow came in with no winds and now sits on these slabs.
Avalanche Summary
Skies and peaks were mostly obscured today by the weather. Very few natural avalanches were observed between Jasper and Parkers ridge. However, good results were produced by avalanche control up to size 2.5 slabs in the parkers ridge area. These slid on weak layers lower in the snowpack.
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.
