**Orange Alert: 1 department, Yellow Alert: 7 departments.** Heavy thunderstorms affected the PACA region on Wednesday, bringing the risk of runoff and flooding. In the Var department, locally up to 50 to 80 mm of rain were expected in a few hours, which is why the orange alert remained in place. Travelers were advised to be very cautious and avoid entering flooded roads. In a second phase, new thunderstorms, sometimes very intense, affected Languedoc-Roussillon in the late afternoon. These thunderstorms shifted eastward and were expected to reach Provence and Corsica during the evening and early night. Hail and strong gusts, locally exceeding 80 km/h, were expected under these thunderstorms. The risk of tornado-like phenomena, such as tornadoes and waterspouts, could not be ruled out, especially near the coast. These thunderstorms were later expected to move toward Italy in the early morning of Thursday. Calm was expected to gradually return, and the alert would therefore be lifted for the southeast. However, the passage of an active disturbance was expected to bring heavy, prolonged rain on the eastern side during Thursday. Depending on the expected rainfall totals, an alert could be issued by services for these rains, particularly in the Auvergne-Rhône-Alpes region. On Wednesday in the early afternoon, the heavy thunderstorms were concentrated in Provence, mainly in the Var department where the thunderstorms regenerated. Active thunderstorm cells were also developing between Corsica and the mainland. Rainfall totals had been significant since Tuesday evening. In some places, the equivalent of a month's precipitation had fallen in 12 hours. Since last night, the following rainfall totals had been recorded: - 236.7 mm at Castanet-le-Haut (34) - 182.9 mm at Caylar (34) - 158.8 mm at Lunas (34) - 147.8 mm at Plans (34) - 135.2 mm at Lodève (34) - 132.3 mm at Cambon-et-Salvergues (34) - 123.5 mm at Murat-sur-Vèbre (34). Heavy rains continued and regenerated over the Var in the Wednesday afternoon and evening. Meanwhile, new thunderstorms, sometimes very intense, were forming over Languedoc-Roussillon in the late afternoon. These thunderstorms were shifting eastward and were expected to reach Provence and Corsica during the evening and early night. An additional 20 to 50 mm of rain was expected under these thunderstorms. Instability was expected to quickly decrease during the night. From Wednesday night to Thursday morning, instability was expected to quickly decrease during the night over PACA. However, new thunderstorm bursts were expected over Corsica, with significant rainfall totals, as well as strong gusts. In the early morning, instability would quickly move toward Italy. The change in weather was confirmed on Wednesday with the arrival of a depression over France. After several weeks marked by mild weather, a much cooler air mass was expected to arrive, leading to a temperature drop of 10 to 15°C in a few days. After weeks of drought, rain finally returned in a generalized manner over France between Tuesday and Thursday. After an exceptionally mild beginning of October, autumn was expected to take its course again. If people were still enjoying terraces or outdoor activities, they were advised to be cautious. With a national thermal indicator close to 19°C and maximum temperatures often between 24 and 28°C on Tuesday, October 6, the weather still resembled early autumn. However, temperatures were expected to significantly drop starting Wednesday and especially Thursday and Friday.
