Give the storm snow a few days to settle. Expect the danger rating to increase if the sun comes out especially in the afternoons.

Snowpack Summary
A significant amount of snow arrived with warm temperatures and relatively light winds Friday-Saturday. This snow created a storm snow instability on all aspects and elevations yet mild temperatures helped keep things relatively in place. The new snow sits on previous windslab surfaces at treeline and above. Faceted weak snow at lower elevations.
Avalanche Summary
Explosive control work produced some size 3 soft slabs in the Icefields and Maligne lake alpine areas. They slid on the storm snow interface. A few dusted the highway. Natural activity was limited but a few size 2-3's were noted. Winds still need to slab up the storm snow. Gullies above polar circus were 85% cleaned out with control work.
Confidence
Timing or intensity of solar radiation is uncertain on Tuesday
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.
