According to the Pas-de-Calais prefecture, more than 370 people have had to be evacuated since the start of this new episode of flooding, including 115 since Wednesday morning. Christophe Béchu, the minister of ecological transition, and Olivier Véran, the government spokesperson, go to Arques, where the Aa passes, Thursday morning, before going to the Montreuil-sur-Mer region at the start afternoon, meeting elected officials and affected residents.
The Aa still on red alert
Thursday morning, more rain will invade Brittany. In the afternoon they will reach the Pays de la Loire to extend to Hauts-de-France. The westerly wind will reach 70 to 80 km/h in Brittany, temporarily up to 90 km/h and even 100 km/h on the south of the Breton coasts.
In Pas-de-Calais, the Aa, placed on red alert since Tuesday, “is generally at the same level as in November”, when it reached its highest historical level, Vigicrues described to the Agency France-Presse. Levels could still increase “very slightly”, but “we can consider that we are at the peak of this flood”, adds the organization.
