Rapid snow loading accompanied by moderate to strong winds will result in storm slab avalances toward Friday afternoon when the bulk of the snow arrives.
Up to 40cm of new snow accompanied by strong winds is expected in the next 24 hours. The avalanche hazard will rise through Friday as snow accumulates as low as 1400 meters. If the forecast is correct, the avalanche hazard will rise to considerable.
Rapid snow loading accompanied by moderate to strong winds will result in storm slab avalances toward Friday afternoon when the bulk of the snow arrives.
Expect loose dry avalanches to run far on the previous ice crusts.
A previous loose, wet avalanche cycle has occurred throughout the region.
A dusting of new snow overlies a well-settled snowpack above 2100 meters . Below 2100 meters, a hard rain crust is the dominant layer in the snowpack. Below 1700 meters, the snowpack is below threshold (not enough snow to avalanche).
Periods of rain, sometimes heavy. Snow lowering to 1600 metres.
Wind at 1000 metres
Northwesterly 50 km/h, easing to 30 km/h in the afternoon.
Wind at 2000 metres
Northwesterly gale 80 km/h, easing to 60 km/h in the afternoon.
Freezing level
1800 metres, lowering to 1400 metres in the evening.
Snow remains on most of the main passes and tramping routes. Sliding into rock is a potential hazard. Ice axe and crampons should be part of your winter gear.
