Storm Ciaran will hit the northwest of the country between Wednesday evening and Thursday morning, Meteo-France warned Monday, October 30, in its latest meteorological update. Gusts of wind “which could reach 100 to 120 km/h inland and on the coast 120 to 140 km/h or even locally 150 km/h” are expected, with a risk of “wave-submersion over the entire Atlantic coast and the English Channel”.

In its bulletin published at midday, the meteorological service classified Storm Ciaran among potentially “dangerous” phenomena. After having formed off the coast of Newfoundland, to the west of the Atlantic, the latter will particularly affect the Atlantic coast, Brittany, Normandy, Hauts-de-France, Ile-de-France, France and Centre-Val de Loire.

This will mean that very strong winds will hit part of France and that strong waves are expected along the Atlantic coasts and the English Channel. “The risks of marine submersion will be greatest during high seas on Thursday at 6 a.m. on the Atlantic coast, and high seas on Thursday between 12 and 2 p.m. on the Channel coast,” specifies Météo-France. In addition, waves of 6 to 8 meters on the Channel coasts and 8 to 10 meters on the Atlantic are expected.

On Thursday, the weather “will remain unsettled”, according to Meteo-France, with rain in the south and showers in the north. “A rainy and windy disturbance will approach the Bay of Biscay at the end of the day,” adds the meteorological service in its report.
