Season 2016 has finished.
Wind Slab 28 Sep
The new snow that came fell on 30cm slush. The top 10cm of the slush froze but the rest is still just preserved. This is causing a layer of instability. the new wind slab is becoming cohesive. If the predicted 40 cm of snow comes later in the week we may update the danger level due to the size and consequence of the new layer.

Wind Slab 14 Sep
14/09/16
With the latest snowfall which started on the 14th of Sept, it has already created a 30 cm deposit. With this snow fall there is a lot of wind loading on South East aspects. This snow has fallen on a melt/freeze surface layer. Hand shear tests from today have shown that this new snow has not bonded to the melt/freeze layer it has fallen on. Caution is required on slopes over 25 deg on the loaded SE to NE aspects

Wind Slab/22-24 July
There has been a lot of wind and it has blown the 15 cm of new snow and created wind slab in lee slopes. This new snow has fallen on a layer of melt freeze from the rain from the 22nd of July. From the compress test results the new wind slab has bonded well to the melt freeze layer. There are 2 new layers of new snow that have fallen in this latest even and there is instability between the two different density layers at 15 cm. See pit results for more information

Wind Slab/Storm Slab 12-13 July
There has been a lot of snow and it will have blown and settled to form deep pockets of wind slab. This new snow has fallen on a layer of melt freeze from the rain and Solar from last week. This could cause a weak layer that will stay around for the near future. Again please give the snow time to settler and bond before hitting terrain of plus 30 degrees.
