At the meteorological crossroads of three climate systems (oceanic, Mediterranean and continental), Aude is particularly exposed to extreme rain events. Take for example 2018, when the Department received three months of rain in several hours. In 2020, even though the extreme rain fell in the neighbouring Departments of Pyrénées Orientales and Ariège, massive amounts of water flowed downstream into the Aude region... This is the area where SCO France is experimenting with the FLAude project, with the aim of reducing vulnerability to flooding. Since the regions of France are at the core of the SCO approach, the onus must be on listening to them to identify their requirements and determine what indicators would be useful for them. On the agenda of the project consortium meeting for the 26th of January 2021.
