The highest temperature ever measured across France in the entirety of record keeping was set on Friday afternoon. Temperatures soared to 45.9 C (114.6 F) at Gallargues-le-Montueux in southeastern France, exceeding the nation's previous all-time record high of 44.1 C (111.4 F) at Conqueyrac on Aug. 12, 2003.

Amid the unrelenting grip of dangerous heat, France's national weather service issued the first ever "red" hazardous weather warning for southeastern portions of the country on Friday. A "red" warning is the highest level out of a four-level alert system put into effect after the deadly 2003 heat wave that claimed 15,000 lives, according to the Associated Press.
