Overview
- Violent hailstorms and heavy rains on Monday evening caused flooding, fallen trees, and evacuations in southwestern France, prompting hundreds of firefighter interventions.
- Météo France has kept six southwestern departments and the Var under orange vigilance for heavy rain and flood risks as of Tuesday morning, May 20, 2025.
- Rainfall accumulations have reached up to 78 mm in some areas, with further intense precipitation expected, particularly in the Var, where totals could exceed 120 mm in three hours.
- The possibility of extending orange alerts to Auvergne departments, including Haute-Loire and Cantal, remains under consideration by Météo France.
- Spring weather patterns, driven by interactions between Mediterranean and Atlantic air masses, are contributing to the rapid development of these severe thunderstorms.
