Since Sunday evening, storm Floriane has been sweeping France from west to east, more precisely from Vendée to the Ardennes. It causes strong winds in its path, especially in Rhône-Alpes and Val de Saône, as well as heavy stormy rains in the Cévennes.
At 1 p.m. Monday, Météo France placed four departments on orange alert for violent winds, including the Rhône. Others on yellow alert for violent winds should also be monitored. This is particularly the case for Ain.
