What causes these storms and which regions will be most vulnerable?
They are associated with a drop in cold in the Atlantic region. It brings increased humidity between Brittany and the Grand Orient to the Alps via the Paris Basin, Center Val de Loire and Auvergne. These storms remain scattered but can be severe at times.
