Hungary and France impose top-level heat alerts amid soaring temperatures
Hungary activated a level‑three heat alert at midnight on 30 July 2026 as temperatures were forecast to reach 40 °C, prompting the government to prepare temporary energy‑use restrictions for large industrial consumers while exempting hospitals and other public services. The heat emergency also triggered a “red code” that obliges social‑care institutions to shelter vulnerable people, and the alert will remain in force until midnight on 4 August 2026.
In France, Météo‑France placed 23 departments under orange heat vigilance and 48 under yellow storm vigilance on the same day, with local temperatures expected to climb as high as 42 °C in the southwest. The heatwave is adding strain to agriculture, energy demand and public finances, and a recent fire in the Gironde and Landes regions burned 42 000 ha and forced the evacuation of 220 000 people.
Separately, the prefecture of Doubs declared five fire‑risk zones orange on 29 July 2026, tightening restrictions on open fires, fireworks and vehicle use between 14:00 and 22:00 to curb the heightened fire danger caused by the prolonged heat.
