Avalanche danger will increase throughout the day as snow continually accumulates. Stick to mellower terrain and back off when the storm intensifies.
New storm slabs will rapidly grow with 20-35 cm of new snow expected to fall by Sunday evening. Human triggered avalanches will be concern on steep or wind affected slopes.
A cold front crossing the region Sunday will bring heavy snowfall with freezing levels staying below 1000 m.
SATURDAY NIGHT: Cloudy, light west wind, treeline temperatures drop to -4 C.
SUNDAY: Heavy snowfall starting in the morning with 20-35 cm by the evening, 40-60 km/h south wind, treeline temperatures reach -2 C.
MONDAY: Another 15-20 cm of snow by the morning then sunny in the afternoon, 20-30 km/h west wind, treeline temperatures around -3 C.
TUESDAY: Mostly cloudy, 20-30 km/h southwest wind, treeline temperatures around -3 C.
Avalanche control on Saturday morning produced a few small (size 1) storm slabs, but for the most part the recent snow was unreactive to ski cutting. On Sunday fresh storm slabs will grow as snow accumulates throughout the day, with natural avalanches possible during the peak of the storm in the late afternoon.
By Sunday evening there will be another 20-35 cm of fresh snow accompanied with strong southwest wind. This will bring storm totals since Thursday to 40-70 cm, creating thick slabs. North facing slopes will have the thickest slabs due to wind loading.
Along ridgelines, cornices are large and always have the potential of failing or being triggered from the weight of a human.
