Official Generalitat classification: the INUNCAT (flood) and INFOCAT (wildfire) special plans, Departament d'Interior. The flood level is the maximum across every flood type affecting the municipality. Wildfire hazard is expressed relative to the Catalan average, not as an absolute probability. Fires (2011-2024, Departament d'Acció Climàtica) are attributed to the municipality where they started, so the burned area may extend into neighbouring municipalities.
