LOW

NSW Main Range

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/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.
