Wild, windy and cold fingers

7th April 2022

A wild and windy day. New snowfall to glen level, with enough depth at the Cas car park to allow for skinning through the ski area.

The Northerly winds were cold and relentless over the plateau and as is common with Northerly airflow – very little visibility. There were some brighter spells during the afternoon but visibility was much reduced.

Areas of fresh windslab have developed on South-East, South and South-West aspects above 900 meters. Cross loading has also affected West and east aspects. Wind exposed slopes are scoured and the old, re-frozen and firm snow is exposed.

The Northerly airflow is continuing with more forecast snowfall. Time to find my warm winter gloves again!

A new cornice rapidily forming in the strong Northerly winds on the rocks above Stac an Fharaidh.

Graupel, rimed snowflakes that form below -30 degrees Celsius.
