Avalanche problems in the area
Problem
Persistent weak layer
Height
Above 400 m
Aspect
N - NW
Probability
Likely
Size
3
Persistent weak layers have recently been observed in the snowpack. Movement within wind slabs can trigger larger avalanches on underlying persistent weak layers.
Problem
Wind-drifted snow
Height
Above 300 m
Aspect
N - NW
Probability
Likely
Size
3
Lately, southerly winds have been dominant, and unstable slabs have formed in northeast-facing slopes but are likely also present on other aspects. A N-blizzard is forecast from Wednesday through Friday, which will result in considerable slab formation on south-facing aspects.
Keypoints
There are still persistant weak layers in the snowpack, and many thin but wide avalanches occurred in NW–SW drifting snow last week. Tomorrow, Wednesday 11 March, and lasting until Friday, a blizzard is forecast with a fresh to strong N–NW wind and significant snowfall. Considerable snow accumulation and slab formation can be expected on south-facing aspects, and avalanche danger is likely to increase as a result.
Snow layers and snow cover
Weak layers can still be found in the snowpack, and many avalanches with considerable extent occurred in NW–SW drifting snow last week. In the middle of last week, and again on Friday, temperatures briefly rose to around 0°C at approximately 1000 m elevation, which has likely slowed the faceting of crystals and may have broken down weak layers in the snowpack below roughly 500 m. On Wednesday, 11 March, a low-pressure system will pass east of the country, bringing northerly winds, blizzard conditions, and significant snowfall through Friday. As a result, increased avalanche danger can be expected due to substantial snow accumulation and slab formation on south-facing aspects.
Recent avalanches
Multiple thin but wide slab avalanches fell last week in strong SW (and NW) winds with snowdrift.
Weather and weather forecast
A low-pressure system will approach the eastern part of the country during the early hours of Wednesday, bringing N–NW blizzard conditions and significant snowfall through Friday.
