South Rockies

An unstable weather pattern will bring clouds, sun and flurries Monday. Sporadic flurries and wind will continue to promote wind slab formation at upper elevations.

There have been no reports of recent avalanche activity in the region. That being said, a size 3 natural triggered deep persistent slab avalanche was reported March 28 in Highwood Pass in Kananaskis Country to the north. This was associated with warm temperatures and sun.

New snow and wind are forming wind slabs at higher elevations.

The mid snowpack holds several persistent weak layers including layers of surface hoar in wind-sheltered terrain and sun crusts on south facing slopes. No recent activity has occurred on these layers.

The lower snowpack is made up of a widespread layer of large, weak basal facets and depth hoar in some areas. Neighboring Kananaskis Country reports continued avalanche activity on this layer. Avoid thin and rocky areas where this weak layer is more likely to trigger.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
