Low

Mount Twynam

18/07/2016
Currently Low danger on all aspects. The 70cm wind slab has bonded well to the melt / freeze layer from last rain event.

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.
