A storm may increase avalanche danger for parts of the region. Danger will be LOW until at least ~10 cm of snow accumulates. Watch for changing conditions over the course of the day.
Storm slabs may develop as the day progresses. The snow may not bond well to underlying surfaces, particularly where it sits on a hard melt-freeze crust. Wind slabs have the potential to form in lee terrain features if the snow falls with elevated wind speed.
SATURDAY NIGHT: Increasing clouds, 40 km/h southwest wind, alpine temperature 0 C, freezing level 2100 m.
SUNDAY: Cloudy with snowfall, accumulation 5 to 15 cm with local amounts up to 20 cm possible, 20 km/h southwest wind, alpine temperature -4 C, freezing level 1600 m.
MONDAY: Clear skies, 10 km/h northwest wind, alpine temperature 1 C, freezing level rising to 2200 m.
TUESDAY: Clear skies, 10 km/h southwest wind, alpine temperature 1 C, freezing level 2300 m.
Looking forward, avalanche activity may spike during Sunday as the new snow accumulates, particularly where it overlies a hard melt-freeze crust.
New snow is forecast at higher elevations for Sunday with elevated wind. The snow will fall onto a hard melt-freeze crust everywhere except above 2000 m on north aspects, where it will fall onto previously wind-affected snow. Below the rain-snow line, rain will soak an already wet snowpack.
