    25cm of storm snow fell near Cameron Lake on Fri Jan 27 (up to 50cm in the townsite). This snow has been redistributed in to wind slabs in lee areas since then, by moderate to strong wind with variable direction. These slabs could be as deep as 50cm (deeper in Eastern side of park).

Avalanche Summary

Three wind slabs up to size 1.5 were observed from the Akamina Parkway today (Jan 30). They likely occurred within the last 24 hours.

Snowpack Summary

Moderate to strong, variable wind has redistributed recent storm snow (20cm near the Divide and 40-50cm in the Eastern park) into wind slabs. This overlies old wind slabs or the mid-January crust that exists to 2400m. The mid-pack is well settled and overlies basal facets and depth hoar, especially in thin areas.

Weather Summary

Wind in the strong to extreme range from the NW will persist through until Thursday. Temperatures will also slowly rise to -5 in the valley and -7 at the ridge by Thursday. Trace accumulations of snow may occur on Wednesday.
