Another very cold but mostly dry day.  The old snowpack is extremely firm and icy and is most widespread on all aspects and plateau areas above 950 metres.  Localised unstable windslab has accumulated around the top of some of these slopes.  In these areas a small avalanche could be triggered; this could potentially lead to a serious outcome of being carried down a steep icy slope below.  See the latest avalanche forecast for more information.
