East Kakwa, Tumbler.
Warming temperatures and sunshine are likely to increase sensitivity of wind slabs.
Strong southerly winds have formed stiff wind slabs sitting over a weak, facetted base.
No new avalanches have been reported. There are very few field observations coming from this forecast area. Remember that a lack of avalanche reports does not necessarily mean a lack of avalanche activity.
If you go out in the backcountry, please consider sharing your observations on the Mountain Information Network (MIN).
The snowpack is shallow, faceted and highly wind-affected. Expect scouring on windward slopes and isolated pockets of deep wind slab over facets near ridge crests on leeward slopes. A crust has formed on the surface below treeline.
Several crusts exist in the mid pack. Isolated pockets of buried surface hoar could be found in sheltered terrain.
Average snowpack depths at treeline are highly variable (20 to 70 cm). Many hazards are on or just below the surface.
