🌬️Entre mercredi soir et jeudi matin, la tempête #ciaran va toucher le quart Nord-Ouest du pays avec de très fortes rafales de vent.
🌊Attention également au risque de vagues submersion sur toute la façade atlantique et la Manche

The wind from Storm Ciaran is expected to be accompanied by a "submersion wave phenomenon" with "very strong waves expected" along the entire Atlantic coast. 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 risks of wave-submersion are particularly feared in the departments of the Atlantic coast which are already in danger. affected by storm Céline during the last weekend of October. Flooding is already happening. occurred in certain coastal towns such as Cap-Ferret, Noirmoutier, at Quimper or even in Pornic and the tides were more important.

Brittany will be affected and could be the region most exposed to the virus. Storm Ciaran. Three of its departments are already in operation. on orange alert for the night of November 1st to 2nd, because it is through the Breton tip that the depression will arrive in France before sinking into the lands of the northwest quarter. The Breton coastline and the Normandy coasts are within easy reach. monitor.
The lands of Normandy and Pays-de-la-Loire could also be affected, as well as the regions of Hauts-de-France and Ile-de-France. and Center-Val de Loire although in these areas the risk seems less significant for the moment according to Météo-France.
To a lesser extent, some departments in the south-west, notably Gironde and Landes, could be swept by the tail of the storm during the night of November 2 to 3 with winds at 50°C. 100 km/h and waves between 6 and 7 meters, or even up to 100 km/h. 10 meters exceptionally in the Bay of Biscay. Note that the final trajectory of the storm has not yet been finalized and that the forecasts could be adjusted.
A storm reinforced by the jet stream
Storm Ciaran must gain strength during its crossing of the Atlantic. This depression coming from the American continent swells under the effect of the very powerful winds of the “jet-stream current”. 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>
