In addition to the orange warnings for snow and ice, orange warnings for violent winds, from the Atlantic coast to the Alps, for the day of this Thursday, November 21.
If the north will be affected by snow, the south will be affected by violent winds due to the passage of the Caetano storm over France. 19 departments from the Atlantic to the Alps have been placed on orange alert for violent winds for the day of Thursday, November 21, Météo France announced this Wednesday. The start of vigilance by Météo France is set at 9 a.m.
This concerns Finistère, Morbihan, Loire-Atlantique, Vendée, Deux-Sèvres, Charente-Maritime, Gironde, Charente, Vienne, Haute-Vienne, Creuse, Allier, Puy- de-Dôme, Loire, Rhône, Isère, Ain, Savoie and Haute-Savoie.
“The exact trajectory of the Caetano depression, expected to circulate from Brittany to northern Italy, could still fluctuate slightly, and cause a slight readjustment of the departments concerned by orange vigilance,” Météo France said.
In addition, 33 departments are now placed on orange alert for snow and ice by Météo France. There were 28 of them in the last 1 p.m. bulletin.
Snow and ice vigilance affects the following departments: Côtes-d'Armor, Ille-et-Vilaine, Calvados, Eure, Manche, Orne, Mayenne, Sarthe, Eure-et-Loir, Loir-et-Cher, Loiret, Aube, Yonne, Haute-Marne, Côte d’Or, Vosges, Haute-Saône, Doubs, Territoire de Belfort, Haut-Rhin, Paris, Seine-et-Marne, Yvelines, Essonne, Hauts-de-Seine, Seine-Saint-Denis, Val-de-Marne, Val-d'Oise, Seine-Maritime, Alpes de Haute-Provence, Hautes-Alpes, Nièvre and Dear.
Up to 130 km/h
Storm Caetano will indeed sweep across France from east to west this Thursday, causing snowfall to the north of its trajectory, from northern Brittany and Normandy to the Grand Est. The wind will blow south of Caetano's trajectory, starting on the Atlantic coast and then shifting to “a Poitou-Charentes/Northern Alps axis”, specifies Météo France.
On the coast, gusts of up to 120km/h are expected, or even up to 130km/h on the “exposed islands and capes”. Inland, they will be able to reach 100 km/h with peaks of 110 km/h “more occasionally”.
“On the terrain, we can reach 110 to 130 km/h on the Massif Central and more than 150 km/h on the highest points of the Alps,” specifies the meteorological institute.
