Météo France announces waves between 8 and 10 meters all around the ocean. The Kéraunos observatory fears waves measuring up to 13 meters. It will be necessary to be vigilant to the risk of submersion and flooding which will be reinforced by the fairly low atmospheric pressure which will raise the water level. Precipitation "sometimes sustained" are also mentioned in this article. by forecasters.

The current is a sort of corridor several thousand kilometers long in which depressions circulate freely. It marks, as it were, the separation between the cold air coming from the north pole and the warm air coming from the tropics, a contrast which only reinforces the depressions.< /p>
