Storm Aurora will sweep across the west and northwest of the country. Nine departments were placed, Wednesday, October 20, in orange vigilance for strong winds. The alert issued by Météo-France concerns Finistère, Morbihan, Côtes-d’Armor, Manche, Calvados, Eure, Seine-Maritime, Oise and Somme, from 4 p.m. and until 4 p.m. Thursday.
“The Aurora storm, the first fall storm, should give a classic remaining episode for the season. But, given its precocity, special monitoring is required ”, warns Météo-France, which plans “A strong gust of wind (…) in the first place on the Atlantic coast, which then spread inland in the northern half of the country ”. In the second part of the evening, this gust of wind “Gradually shifts to the east, then it is the departments bordering the Channel which are then concerned”.
In the nine departments placed in orange vigilance, gusts of 100 to 110 km / h are expected along the coasts. They can reach locally 120 km / h and up to 130 km / h on the Channel coast. They are expected between 90 km / h and 100 km / h, with peaks at 110 km / h locally, in the interior.
Falling trees and cut roads
The Loire-Atlantique firefighters, who report falling trees, cut roads or electric wires on the ground, launched at the beginning of the evening a message of caution to citizens, asking them: “Do not go out, stay in a sheltered place, do not take your vehicle, do not saturate the emergency lines. Calls to 112 and 18 should only concern emergencies. Our priority is to respond to urgent interventions ”.
The sector of Quimperlé (south-Finistère) is affected by falling trees or power cuts, as is that of Rostrenen (Côtes d’Armor) where roofs have been blown up and telephone lines have fallen to the ground , according to the regional press.
Note that in the neighboring departments, placed in yellow wind vigilance, occasional gusts around 100 km / h, or even more, very locally are not to be excluded, underlines Météo-France. “Vortex phenomena are also possible, without being able to claim to locate them given the associated uncertainties”, adds the meteorological service.
Associated with the Aurora storm, a yellow wave-submersion vigilance was also issued for Finistère, Morbihan and Seine-Maritime.
In a statement, the prefect of Morbihan, Joël Mathurin, called on the population to limit their movements until the end of the alert. “Do not walk in the forest or on the coast. In town, pay attention (…) possible falling objects. Store or secure objects that are sensitive or liable to be damaged ”, he advised.
