Météo-France has placed 43 departments under orange vigilance for an extreme heat wave occurring this Thursday and Friday [1].
The alert comes as France faces a spike in temperatures that threatens public health and strains water resources across the country. Local authorities are issuing warnings to residents to limit water use and take precautions against heat-related illness.
Forecasters expect temperatures to climb up to about 37°C during the peak of the heat wave [5]. This represents a significant escalation in the weather event, which has seen a growing number of affected regions throughout the week. On Sunday, Aug. 9, 21 departments were under orange vigilance [3], and that number rose to 22 by Monday [2].
While most of the affected areas remain under orange vigilance, the situation is more critical in some regions. Nine departments have been placed under a red alert [6]. This highest level of warning has triggered the government to launch the ORSEC plan, a specialized emergency organization system used to coordinate response efforts during major crises.
Conflicting reports have emerged regarding the exact number of departments under orange vigilance for Thursday. While some reports suggest 31 departments [4], other data indicates the number has reached 43 [1]. Météo-France continues to monitor the situation as the hottest days of the week arrive.
The meteorological service has emphasized the need for vigilance as the heat peak persists through Friday. Residents in the affected 43 departments are encouraged to follow official health guidelines to avoid heatstroke and dehydration.
“43 departments under orange vigilance for an extreme heat wave”
The escalation from orange to red alerts in nine departments indicates a shift from a general public health concern to a state of emergency requiring coordinated government intervention via the ORSEC plan. This reflects the increasing volatility of European summer weather patterns, where rapid temperature spikes necessitate high-level civil protection responses to prevent mass casualties and infrastructure failure.
