  6. Risk of flash floods and swollen waterways in affected southern French departments

    Serious risk of flooding and flash floods are expected in the three departments under orange alert, particularly in areas receiving heavy rainfall from the thunderstorms. Additional flooding risk extends to downstream areas in plains that will collect runoff water from the elevated terrain of the Cévennes. The potential for intense rainfall spread to coastal zones before the weather episode concludes increases flooding hazard in those areas as well.
