Overview
- A cévenol pattern is establishing from Friday, concentrating persistent rainfall from the Cévennes and Gulf of Lion on Saturday before shifting heavier totals toward the Roussillon and eastern Corsica on Sunday.
- Forecasts indicate 72‑hour rainfall commonly reaching 100–200 mm, with localized 250–300 mm possible on exposed reliefs and around 100 mm in parts of Provence.
- East to southeast winds will strengthen along coasts and ridges, with gusts frequently 70–90 km/h and rough seas on the Mediterranean.
- Significant mountain snowfall is expected with a rain–snow line near 1,200–1,600 m, including heavy accumulations in the eastern Pyrenees and notable snow in the southern Alps and Cévennes.
- River services urge monitoring via Vigicrues as overflows and runoff are possible in saturated basins, while northern regions stay mostly dry with seasonably mild temperatures.
