Nine departments of the Center-East are placed in orange alert for thunderstorm on Saturday until 6:00 p.m. by Météo-France, which added the Haute-Loire, the Ardèche and the Drôme at 10 a.m. in addition to the six departments already concerned.
Hailstorms
These three departments join Ain, Isère, Allier, Loire, Puy-de-Dôme and Rhône, placed in vigilance for 6 hours by Météo-France. “An extension of orange thunderstorm vigilance to neighboring departments is not excluded,” said the meteorological service in its 10h bulletin, which calls for “informed” of changes in the situation.
Thunderstorms will last “a good part of the day despite periods of lull” and will be accompanied by “strong rainy intensities and hail risks” warns the agency. Cumulatives of rain from 30 to 60mm “in fairly short periods of time (typically in less than 3 hours)” and “very locally” are expected, specifies the service in its bulletin.
“The risk of gusts of wind is less marked but present,” he adds. The meteorological service has raised orange vigilance at the English Channel and Calvados at 8 a.m., where bumps for rain of 20 to 40mm were raised overnight.
