The storm slabs remain soft where the wind has not firmed them up. Soft slab conditions also exist on gully sidewalls and some large alpine slopes.
Weather Forecast
Some light flurries (rain showers in valley bottoms) possible on Sunday as a frontal systems moves through. Westerly winds will increase to strong and temperatures will be a little cooler than Saturday. Another pulse of snow is forecasted as early as Monday night.
Snowpack Summary
Wind slabs are developing below alpine lee ridge lines with gusty moderate West winds. In sheltered areas, the recent storm snow has settled and bonded well. Expect a suncrust on southerly treeline aspects and widespread suncrust over the recent storm snow at lower elevations.
Avalanche Summary
Heli bombing had good results on the settled pockets of storm slabs above the Maligne Road on the Medicine Slabs. No other activity was noted or reported but expect that a few small solar initiated slides occurred on steep south facing slopes below treeline on Saturday.
Confidence
Intensity of incoming weather systems is uncertain on Tuesday
