Sunday: Sunny. Light southwest winds. Alpine high temperatures around -3 with freezing levels to 1700 metres.

Monday: A mix of sun and cloud. Moderate northeast winds. Alpine high temperatures around -4 with freezing levels to 1700 metres. 

Reports from the Kootenay Pass area on Thursday describe periods of intense solar warming triggering several natural point releases entraining our recent storm snow up to size 1.5.

A similar pattern is likely to occur through the weekend as fresh accumulations are once again triggered by their first exposure to solar input. New and recent wind slabs may also be reactive to triggers in leeward terrain features, especially in areas with greater recent snowfall amounts, such as Kootenay Pass.

Light new snow amounts over Friday night will accumulate over a new melt-freeze crust on solar aspects and otherwise add to a rapidly settling 5-20 cm of snow from Wednesday's storm. This previous storm snow formed wind slabs on north through east aspects, overlying yet another crust on all aspects below 2000 metres. Wind affected new and recent accumulations may add to settled dry snow in limited terrain above this elevation. 

• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Even brief periods of direct sun could produce natural avalanches.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
