Situation
Within a highly unstable context with a maritime polar descent over Western Europe, a depression is rapidly deepening over the Gulf of Genoa and causing stormy winds over the extremities of Corsica, the Corsican mountains, but also on Provence and Mercantour.
For the ORANGE alert, the wind will significantly strengthen over Corsica over the next few hours. It will blow in violent gusts during the day on Wednesday. Peak winds of 120 to 140 km/h are expected in Balagne, 130 to 160 km/h on Cap Corse, locally 180 km/h possible. On the southern end of the island, we expect 110 to 140 km/h in the Bonifacio sector. Finally, gusts will reach 120 to 150 km/h on the Corsican mountain crests.
?
100 to 110 km/h can be reached in Provence and Mercantour in the two departments placed on YELLOW alert.
Observation
The wind is clearly getting stronger on Corsica as the hours go by. Good gusts are already blowing across the Var hinterland and Mercantour throughout this night.
Evolution
All day Wednesday
It is during the day on Wednesday that the wind will blow the most violently on the island with maximum gusts of 120 to 150 km/h on Balagne and in particular the Île Rousse sector. On Cap Corse, maximum gusts will reach 130 to 160 km/h and it is not excluded to have peaks of 180 km/h. The wind could surge in violent gusts of 90 to 120 km/h across the Bastia region. The wind will be particularly violent on the Corsican mountains with maximum gusts reaching 140 to 160 km/h. On the Bouches de Bonifacio, maximum gusts will be between 100 and 130 km/h.
The expected gusts will be lower in Provence and the Nice hinterland, hence the IMPORTANT RISK level alert, with gusts of between 100 and 110 km/h.
