Be weary of hard slabs in large alpine/treeline features.
Previous NE winds reverse loaded alpine features North of Sask x'ing. More evident in the North bulletin area. This, in combination with basal facet issue produced a few random large destructive avalanches yesterday.
Several natural large avalanches observed yesterday due to the combination of rapid wind loading initiating basal facets or reloaded bed surfaces.
Mnt Athabasca ramp route ran size 3.5. Impressive avalanche running into the rock basin below.
A warm upper ridge over the eastern Pacific is beginning to move in from the west, which will gradually flush out the Arctic air that was entrenched over most of Western Canada. More detailed forecast at: Mountain weather forecast
A variety of wind affected surfaces. Wide spread scouring, stripping in exposed places. Hard slabs, soft slabs, sastrugi now present. The Icefields area has a well bridged mid pack overlying basal facets and depth hoar. The northern region is weaker with less bridging midpack strength above basals and depth hoar.
Today: Few size 1-2 loose dry in steep alpine steep rock/gullies due to solar.
