According to Météo France, on average, fifteen storms affect France each year. At sea and on land, the storm is characterized by violent winds generally accompanied by intense precipitation.
Storms occur most often during fall and winter, about 80% in temperate regions, because the oceans are still relatively warm while the polar air is already cold. It is possible to predict the various types of storms, but their frequency and frequency cannot be predicted in advance. On the other hand, storms that occur in arid or semi-arid regions can be predicted as far in advance as they can be.
