About 1,500 people gathered for an illegal rave party in the Lanouée Forest of Morbihan, France, during a severe heatwave [1].

The event occurred while the department was under a red-alert heatwave warning, creating a dangerous intersection of high crowd density and extreme fire risk in a wooded area. Because the forest is difficult to access, emergency services faced significant challenges in ensuring public safety.

The gathering took place from Friday, July 10, to Saturday, July 11, 2024 [1]. The organizers ignored a prefectural decree that explicitly forbade wild rave parties in the region [2].

Local authorities expressed immediate concern over the potential for a wildfire to ignite in the dry undergrowth. The prefect of Morbihan issued a warning regarding the volatility of the environment during the event [1].

"The risks of fire are very high due to the strong heat," the prefect of Morbihan said [1].

Despite the official ban, the event proceeded with a large crowd in a sensitive ecological zone. The Prefecture of Morbihan said that "wild rave parties are prohibited by prefectural decree" [2].

The incident highlights the ongoing tension between unregulated underground events and environmental safety regulations, especially as extreme weather events become more frequent in Brittany.

This incident underscores the increasing difficulty for French regional authorities to manage 'free parties' during extreme weather events. The use of a red-alert heatwave zone for a large-scale unauthorized gathering transforms a public order issue into a critical environmental hazard, potentially forcing the state to implement stricter surveillance or harsher penalties for organizers of illegal events in protected forests.
