Sarthe and Mayenne departments placed under orange flood alert
The French departments of Sarthe and Mayenne were placed under orange rain-flooding alert by Météo-France on May 5, 2026, due to significant precipitation expected throughout the day. The alert was initially set to remain in effect until 6 PM.

Orange alert lifted in Gard and Hérault departments
Météo-France downgraded the Gard and Hérault departments from orange to yellow alert status during the night of May 4-5, 2026, after the intense Mediterranean weather episode that produced record rainfall. The improvement reflected the end of heavy precipitation in these two departments during the night.
