A rare tornado touched down near the towns of Saint-Pierre-des-Landes and Ernée in the department of Mayenne, NW France on Sunday afternoon (LT), September 17, 2023.

The tornado formed between 17:30 and 17:45 LT, on the southern edge of a small but temporarily very active storm cell.

It destroyed several agricultural buildings and damaged the roofs of several homes.

An investigation is in progress to determine the trajectory and intensity of this tornado.

The various supercells that hatched in the western third of the country on the same day produced violent hailstorms, reaching up to 8 cm (3.1 inches) in diameter in the Gers and up to 5 cm (2 inches) in Normandy.

Hailstorms such as these are not very frequent after mid-September, especially so widespread over a significant portion of the territory, Keraunos meteorologists said.

“As a result of the significant spatial extent and intensity of these storms, the day of September 17 became the stormiest September day since our records began in 2009. Indeed, the storm severity indicator (ISO), measured for almost 15 years, stands at more than 25 for the day. This value is temporary because all the damage scores have not yet taken place at the time of writing this news. But the value already exceeds that of 24.94 recorded on September 16, 2015.”
