A further 30 departments from the south-west to the north-east of the country have been placed on yellow alert – the third highest alert after orange and red.
The new warnings come after more than 20 departments were hit by storms overnight Friday – when a tornado caused significant damage in Meurthe-et-Moselle, on the border with Luxembourg.
Thirty houses were damaged in Longwy and Herserange, with 19 people injured in Luxembourg – which bore the brunt of the storm.
