Twenty departments in the West and North placed on orange alert for violent winds

Finistère, Morbihan and Loire-Atlantique are no longer placed on orange “wind” vigilance, according to the latest Météo-France bulletin, published Friday October 23. The forecasting institute had placed 23 departments on orange vigilance in the morning. This vigilance only concerns 20 departments now. This alert is linked to storm Austen, which appeared in the Iroise Sea during the night from Thursday to Friday, and which will then sweep across the Channel. “To the south of the depression, an episode of strong and stormy wind developed during the night from Thursday to Friday then will shift eastward during the day on Friday,” notes the forecaster.

In detail, the departments concerned by orange vigilance are Aisne, Calvados, Côtes-d'Armor, Eure, Ille-et-Vilaine, Manche, Nord, Oise, Orne, Pas-de-Calais, Paris, Seine-Maritime, Seine-et-Marne, Yvelines, Somme, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne and Val-d’Oise.

The institute predicts “gusts reaching 100 to 110 km/h inland, and up to 130/140 km/h in coastal areas” in Brittany. The expected gusts are 100 to 110 km/h inland, and 120 km/h on the coast of the rest of the departments concerned, except in Île-de-France, where we expect 80 to 90 km/h. The English Channel “will be particularly affected by this episode with gusts of up to 120 km/h inland (and 130 to 140 km/h on the coast)”.

Météo-France does not rule out a possible worsening of vigilance. “The rain which will circulate during the day on Friday will be relatively sustained over basins in the west of Pas-de-Calais, already weakened by the rains of previous days,” specifies the bulletin.
