Key Points 

• According to Météo France, temperatures are expected to continue rising over the next few days throughout the region, with extreme values beginning on Sunday. The heat wave could last at least until Friday, June 26, and could be comparable to the one in 2003.
• A regional analysis of emergency care utilization indicates an increase in the iCanicule composite health indicator (which includes heatstroke, dehydration, and hyponatremia) since the start of the heatwave. This trend falls within the expected range given the current weather conditions. The trends in the monitored indicators are consistent across all departments.
