What does an orange heatwave alert mean?
Once this level is reached, the department's local prefect takes all necessary measures to address the heatwave, in accordance with the Plan de Gestion d’une Canicule Départemental (PGCD). The following steps are usually taken:
- Communication is increased to make people aware of the dangers of heatwaves and what they can do
- In retirement homes, a “plan bleu” can be announced, which involves greater mobilisation of staff and resources to counter specific threats generally, for example Covid or an outbreak of flu, as well as heatwaves / other scenarios
- Ambulance and nursing services are mobilised
- Mairies establish lists of people vulnerable to heatwaves and can offer support
- Additional support is given to homeless people
