Weather: “significant” accumulations, school trips prohibited… Corsica placed on orange rain-flood alert this Thursday, November 5

The two Corsican departments will be on rain-flood alert from Thursday morning until midnight with heavy accumulations of precipitation expected on the eastern side of the island, Météo-France announces. The Weather Channel confirms this trend, and also places Hérault on orange alert.

The first storms, underway on the coast, “will become more numerous and intensify in the evening/early night”, according to Météo-France. At the end of the night, the accumulations will start to become “significant”, especially on the eastern terrain, with hourly intensities which can be around 20 to 30 mm/h, temporarily around 50 mm/h.

Over the entire episode, accumulations should reach 150 to 200 mm widely and could locally exceed 300 mm on the relief, warns the meteorological agency. The Haute-Corse prefecture took a number of measures for Thursday, in particular prohibiting school outings and using the GR20 hiking trail. She also recommends avoiding any unnecessary travel and favoring teleworking.

Despite some nice clearings, the northeast wind will continue to make the northern half cooler, even if it will weaken slightly. Temperatures will remain below normal, generally 9 to 12°C in the north and 13 to 17°C in the south. The northern half will maintain dry weather, divided between clouds and clearings. The freshness will remain noticeable, particularly under the effect of the breeze.
