Developing windslab and weak snowpack in places.
4th December 2023
From a largely unconsolidated snow cover, the recent winds have started to drift snow and form windslab in specific wind sheltered places. Cold temperatures have produced conditions for the growth of crystals within the snowpack which have formed loose square grains called facets. Additionally cold clear nights has helped with the growth of surface hoar grains which although pretty and fragile surface crystals, when buried by snow they present weak layers at depth. These are the conditions at the moment and although snow cover is mostly unconsolidated, where windslab is present ( in specific places as indicated in the report) this may overlie weak layers at depth.
