Avalanche problems in the area
Problem
Wind-drifted snow
Height

Aspect
S - NW
Probability
Possible

2
Wind slabs are present on S and W aspects following the prevailing easterly winds in recently.
Problem
Persistent weak layer

Above 600 m
Aspect
N - NW
Probability
Likely

During controlled blasting, an avalanche released on the persistent weak layer on December 11th high in Hlíðarfjall. Numerous natural avalanches seen in Öxnadalur, indicating that the persistent week layer is widespread.
Keypoints
An active persistent weak layer is present in the mountains, and wind slabs lie on top of it on S and W aspects. Avoid steep slopes in the mountains where wind slabs rest on an active persistent weak layer. Instability will likely increase further following precipitation on Wednesday.
Snow layers and snow cover
A persistent weak layer is still present high in the mountains. An remote triggered avalanche occurred during controlled blasting in Hlíðarfjall before the weekend, and several natural avalanches have fallen in Öxnadalur in recent days. Wind slabs lie on top of the weak layer on south- and west-facing slopes after prevailing easterly winds. Considerable snowfall is expected in the mountains on Wednesday, which will add snow on top of these slabs and further increase instability.
Recent avalanches
A size 2 avalanche was released with explosives in Hlíðarfjall on Thursday night. It was remote triggered on a persistant weak layer and spread over a large area.
Weather and weather forecast
NE-wind and new snow on Wednesday. Less wind and precipitation on Thursday.
