Extreme Precipitation Risk 2050 (France, DRIAS)
This is a forward-looking scenario layer for France.

What it shows
This is a forward-looking scenario layer for France. It measures how intense the heaviest single-day rainfall is projected to become around the 2050 horizon, helping anticipate where heavy rain will most threaten people, property, farmland and infrastructure through flooding and erosion.
How it is built
The layer reports the projected annual maximum daily precipitation (the wettest single day of the year). It is based on the French DRIAS TRACC2023 climate projection for the ~2050 horizon, at a +2°C global warming level (roughly +2.7°C over France). As a single-model scenario projection, it should be read as a plausible future trajectory rather than an observation. The highest values fall in the Cévennes, the southern Alps and Corsica.
How to read it
Higher values mean more intense projected daily rainfall and therefore greater exposure to flash floods, landslides, soil erosion, infrastructure damage and waterlogging of crops. Lower values indicate milder projected extremes.

Comparison with the WWF Risk Filter Suite
The WWF Risk Filter Suite does not publish a dedicated extreme-precipitation indicator, and this layer is in any case a France-specific, forward-looking 2050 projection. It is a national scenario extension with no distinct WWF equivalent.
