Small pockets of good skiing can still be found in sheltered terrain at treeline. Hielda is skiing surprisingly well.
Be on the lookout for reverse loading from Northerly wind.
Wind slabs sit over a variety of surfaces including old wind slabs, temperature crust and sun crust making reactivity variable. Be extra cautious in areas that wind slabs sits over a hard layer.
This problem is specific to steep, wind protected terrain. Expect more dry loose activity in areas where recent snowfall sits over a hard surface.
Wednesday: A mix of sun and cloud with isolated flurries and trace precipitation. Alpine temperature High -15 C. Ridge wind west: 10 km/h. Freezing level at valley bottom.
Thursday: Mix of sun and cloud. No precipitation. Alpine high -11. NW wind 10-25km/h. Freezing level valley bottom.
Friday: Mix of sun and cloud. No Precipitation. Wind West 10km/h
10-15 cm of recent snow has been redistributed by recent Northerly winds causing reverse loading in many locations with wind slab development in Alpine and exposed terrain at treeline. A weak temperature crust can be found up to 1900m on all aspects with a sun crust on solar aspects up to 2800m. Basal facets & depth hoar present at throughout area
A few Natural size 1 dry loose avalanches were observed on the Icefields Parkway on Tuesday, Feb 22. All occurred in steep terrain with unsupported features.
