Intense rainfall is expected in all the departments facing alerts. 

In the Alpes-Maritimes and Var, rain clouds are likely to remain overhead for most of the day, releasing up to 120 mm of rain. 

State forecaster Météo France says there is little chance of the clouds moving much once rain begins, bringing heavy downpours to affected areas.

In the Cévennes mountains, up to 150 mm to 250 mm is predicted to fall between this morning and Thursday evening. 

Météo France predicts in some localised areas this will be closer to 350 mm. 

The most affected areas will be Aigoual and Mont Lozère – the latter also facing the risk of flooding due to saturation from last week’s rainfall. 

Official advice is to limit outdoor activities in these areas and for drivers especially to avoid flooded roads.
