Due to storm Herminia, the wind will blow strongly this Sunday across part of France. Nine departments in France are in fact on orange alert, Météo-France announces.
The departments of Finistère, Côtes-d'Armor, Pyrénées-Atlantiques, Hautes-Pyrénées and Rhône will be affected by an orange wind alert from around 8 a.m. and at least until midnight. Morbihan will be at the same level of vigilance for rain-flooding from 6 p.m. and until at least 11 p.m., Calvados, Ille-et-Vilaine and Mayenne have been for floods since Saturday. Météo-France, on the other hand, has downgraded Oise and Seine-Maritime to yellow vigilance.
Gusts of more than 100 km/h
“Gusts of around 130 km/h on the coasts and close to 100 km/h inland are expected” in Brittany, according to the meteorological agency, which mentions a “frontal passage associated with Herminia” . “On the Breton tip, saturated soils constitute an aggravating factor,” notes Météo-France, while significant precipitation caused by storm Éowyn has already showered the region.
In the two Pyrenean departments, gusts could reach “110 to 120 km/h in medium mountains as well as locally in valleys”. Peaks of more than 150 km/h are possible on “certain exposed ridges or passes”. And winds of “100 to 110 km/h” are expected in the Lyon region from the evening. The orange alert in the Rhône could even be extended to the entire area.
-Vigicrues sounds the alert
Concerning the risk of flooding in Brittany, “all the tributaries of the upstream basin of the Vilaine are reacting to the rains of the previous two days. Levels will remain high on Sunday and should start to rise again due to the rain expected on Sunday,” explains the monitoring organization Vigicrues. “In Normandy, the situation is stabilized on the Epte which is returning to yellow alert. Significant floods are spreading across the Orne and Dives where levels will remain high on Sunday.”
Still according to the same source, “in Pays de Loire, the Mayenne flood is currently spreading […] Moderate rain on Sunday will keep levels high.” In Morbihan, the accumulations could be “40 to 60 millimeters in twenty-four hours”, with a lull during the night, concludes Météo-France.
