Météo-France has placed 35 departments under red heat-wave vigilance for Sunday, June 21 [1].

This emergency measure coincides with the Fête de la Musique, a major national celebration. The combination of extreme heat and large public gatherings creates significant risks for public health and safety, forcing the government to implement restrictive measures to prevent dehydration and heat-related emergencies.

Forecasts indicate that temperatures could climb as high as 41 °C in some areas this Sunday [3]. In addition to the 35 departments under red alert, another 45 departments have been placed under orange vigilance [1].

To manage the risks associated with the heat, French prefects will issue orders banning the consumption of alcohol on public roads within the red-vigilance departments [2]. This restriction is specifically targeted at the festivities of the Fête de la Musique to ensure public order and health safety.

"Météo-France a placé 35 départements en vigilance rouge canicule pour la journée du dimanche 21 juin," a Météo-France spokesperson said [1].

The ban on public alcohol consumption was confirmed by the Services de Matignon, which said, "Les préfets prendront des arrêtés d’interdiction de la consommation d’alcool sur la voie publique dans les départements placés en vigilance rouge" [2].

Local authorities in affected regions, including Charente, are preparing for the surge in temperature and the corresponding restrictions [5]. The red alert is the highest level of warning issued by the meteorological agency, signaling that the heat is dangerous and requires immediate protective action from the population and local governments.

Temperatures could climb as high as 41 °C in some areas this Sunday.

The decision to ban public alcohol consumption during a major cultural event like the Fête de la Musique highlights the severity of the current heat-wave. Because alcohol increases dehydration and impairs the body's ability to regulate temperature, the French government is prioritizing medical emergency prevention over traditional celebration norms to avoid a surge in heatstroke cases during peak temperatures.
