Situation
In connection with the bad weather in Spain and by the spillover effect of the depression which extends as far as Provence, a rainy-stormy episode occurs in eastern Corsica until Sunday 9 a.m.
Due to the expected accumulations in urbanized areas of the plain and on the coast near Bastia, the situation requires special monitoring. The most risky period occurs between Saturday evening and Sunday morning in Haute-Corse. Be careful of the significant risk of flooding. Stay safe and limit your travel.
Total rainfall can reach 80 to 130 mm over the entire episode, locally more than 200 mm, or the equivalent of 1 and a half months of precipitation in 24 hours. Under the strongest storms, hourly intensities reach 50 to 70 mm/h.
Observation
At 12 p.mstorms are starting to weaken between Hérault and Var, which is why our alert has been lifted for these departments. Since yesterday evening, an average of 20 to 40 mm of water has fallen on the Hérault, up to 62 mm in Saint-Jean-de-Védas (34).
In Corsica, a first big storm has just broken out in the Bastia region where 47 mm of water fell from 8 a.m. to 11 a.m. this morning.
Evolution
From this afternoona strong stormy deterioration affects the east of Corsica and in particular Haute-Corse until early Sunday morning with risks of flooding in the Bastia sector in particular.
Over the entire episode, cumulative rainfall can reach 80 to 130 mm, locally more than 200 mm. Under the strongest storms, hourly intensities reach 50 to 70 mm/h.
Floods can occur as well as the flooding of numerous watercourses descending from the eastern reliefs of the island exposed to the east wind saturated with humidity.
