"Interior BC gets the cleanest short-term shot, and the guidance is tightly clustered on snow arriving Sunday evening, peaking Monday, and fading early Tuesday. It is also reasonably well aligned on rising snow levels and manageable wind outside the most exposed ridges, although intensity still varies enough to keep the biggest totals centered on Revelstoke."
"Snow levels start near valley floors, then climb to roughly 3,000-5,500 feet by Monday afternoon, so the best quality comes early before the snow gets denser late in the event. Expect SLRs mostly in the 14-17 range at the front end for lighter, fairly fluffy snow, then closer to 10-13 and locally 7-9 by Monday night as the snow packs in."
"From Tuesday into Saturday, the storm focus shifts east and the models still agree on the timing better than the details, with the steadiest snow favoring Lake Louise and Banff Sunshine. Where they diverge is on intensity, not on the broader setup: most guidance keeps snow going for several days, pushes snow levels up into the 6,000-7,000 foot range while it is snowing."
A major weather system will impact BC and Alberta in two distinct phases. Interior BC will experience the first wave from Sunday evening through early Tuesday, with Revelstoke positioned for the heaviest accumulation and best powder conditions. Snow levels will rise from valley floors to 3,000-5,500 feet by Monday afternoon, with snow-to-liquid ratios of 14-17 initially, then 10-13 by Monday night as snow densifies. The second phase shifts focus eastward to the Alberta Rockies from Tuesday through Saturday, with Lake Louise and Banff Sunshine receiving the steadiest snow. Snow levels during this period will reach 6,000-7,000 feet, with modest wind impacts and several days of continuous snowfall expected.
