This rainy-stormy deterioration hit Corsica on Tuesday evening and the showers continue during the day. According to Météo-France forecasts, a lull is expected only in the evening.
The episode continues this Wednesday
The meteorological institute recorded cumulative rainfall of between 30 and 60 mm in the most affected areas, and up to 100 to 130 mm more punctually (120 mm recorded in Oletta), around Castagniccia and the eastern plain.
For Wednesday, stormy and locally heavy rains will remain present until at least the evening, “interspersed however with periods of more or less lasting calm”.
“During the most severe storms, we sometimes expect sustained rainfall intensities, generally close to 20 to 30mm, or even 40mm, per hour,” specifies Météo-France, which indicates that “hail is also not excluded.” Locally and punctually, up to 150mm, or even a little more, are expected.
