This intense deterioration was linked to the rise of a depression filled with warm air coming up from the Maghreb, confronted with cool Atlantic air. This conflict of air masses accentuated the violence of the storms.
Stormiest day since the beginning of this year
With 32,497 lightning strikes recorded by METEORAGE, this Saturday was the stormiest day since the beginning of this year. These storms came up from Spain before crossing France yesterday and moving towards Germany tonight.
