Avalanche forecasts

Avalanche conditions

There has been snowing since it got colder last week, most precip in Tröllaskagi and the Eastfjords. There have been strong winds causing a slab formation. An avalanche fell on the road between Isafjordur and Sudavik early on Monday morning.

Forecast for selected areas

Northern Westfjords

Moderate danger

Avalanche fell on the road Sudavikurhlid on Monday morning in strong N-wind, but otherwise slower NE-winds. Quite a lot of new snow was observed on Seljalandsdalur on last weekend with not so good bond to the melt-freeze crust below. Strong N-NE wind on Monday and high temp. gradient in the new snow the last days which could cause a weak layer formations leading to the avalanche. That gradient has decreased but a weak layer could still be present, especially where the snowpack is relatively shallow.
Valid from: 01 May 09:00 GMT - Valid until: 04 May 16:00 GMT

Tröllaskagi

Moderate danger

Warm up to the mountaintops last week and since Thursday last week it has been snowing in NE-winds until Saturday. On Sunday the wind was speeding up in N-NW winds with strong snowdrift and quite a bit of precip at the coast, then turning to NE-wind and calming down on Tuesday. In Siglufjordur the windslab is sitting on top of a weak layer of graupel which seems well bonded with the older snow. High temperature gradient was observed during the weekend in the new snow. That gradient has decreased but a weak layer could be present, especially where the snowpack is relatively shallow as was observed in Olafsfjordur at 300 m elevation in NW aspect. Tests gave easy and medium resistant planar results. An big avalanche fell in Horgardalur valley in a gully that is sensitive to N-NW snowdrift.
Valid from: 01 May 09:00 GMT - Valid until: 04 May 16:00 GMT

East fjords

Considerable danger

Warm up to the mountaintops last week, on Friday last week it started snowing in NE-winds. On Sunday the wind was speeding up in N-NW winds with strong snowdrift and heavy precip and the turning to NE again. Precip on Wednesday in NE-wind. The snowdepth has increased 1 m on automatic sensors but little information are about the stability in the new snow and only small wet avalanches reported as the temp reached freezing level at lower elevations on Monday. A windslab has been building up the last week and if it will fail, avalanches would have potential to be of a resonable size. High temperature gradient was observed on last weekend in the new snow.
Valid from: 01 May 09:00 GMT - Valid until: 04 May 16:00 GMT

Weather forecast in terms of avalanche danger

East and northeast wind 5 to 13 m/s and snowshowers in the north and east, strongest wind by the coast. Ligther variable wind elsewhere, partly cloudy and occasional snowshowers, but fair in the southwest. Temperature 1 to 7 degrees C, during the day, but around and below feezing point in the north and east. On Sunday, Monday and Tuesday: Northeast 8 to 15 m/s, strongest wind by the souteast coast. Mostly cloudy and some snowshowers in the northeast and east and temperature around or below freezing point, elsewhere widely fair and temperature 1 to 6 degrees C.
