In Nice, where the mayor, Christian Estrosi, announced the activation of a municipal command post from 3 a.m. on Tuesday, parks and gardens, cemeteries and recycling centers will remain closed “at least part of the day of October 24, or even the whole day if the situation requires it”according to a city press release.
Friday, in the Alpes-Maritimes which were placed on red rain and flood alert, the flow of the Vésubie jumped from 60 cubic meters per second to 200 m3/s and submerged two temporary bridges, carrying away sections of the roadway and cutting the access to the village of Venanson (170 inhabitants), and to several hundred homes in Saint-Martin-Vésubie. However, these bad weather did not cause any casualties.
In the afternoon, the rains from the south-east will slowly shift towards the Alpine massif and the Côte d’Azur while weakening. On the other hand, they will strengthen to become stormy in Corsica, with a fairly strong southwest wind on the extremities and the relief of the Isle of Beauty.
