  Cooler but sunny periods are forecast, and we could see some of the big cornices start to fail again as the sun heats them up. A cornice release could be the trigger needed to tickle the weaker layers below.

  The Valentines surface hoar layer has been less reactive and is producing harder shears as bridging strength increases. Confidence is slowly building but as it is now buried 70-120cm deep, slopes which get triggered will produce large avalanches.

  Storm slabs up to 50cm thick have been less reactive today,but can be still triggered in steeper terrain. Areas around ridge crests will be most susceptible.
