Storm Fiona caused significant rainfall on the night of September 16-17. These exceptional rains have caused significant damage to Guadeloupe’s road infrastructure. The operation consists of carrying out the works to secure the works following the passage of the storm Fiona. An expertise on the road network was carried out by the Cerema (public establishment under the supervision of the Ministry of Ecological Transition) and made it possible to identify the operations to be carried out.
