“Pierrick” depression: 11 departments placed on orange flood and wave-submersion alert. Météo France asks residents to move away from rivers and bridges and to reach a high point to take shelter in the event of submersion.
For motorists, it is not recommended to drive onto a submerged road. The very strong waves expected on the coast of the north of the country also risk causing pebbles to be projected. “Significant damage is feared locally to light housing and temporary installations on the shore and the coast,” warns the meteorological agency.
