Will Météo‑France place one or more French departments in 'vigilance rouge' for heat on July 18, 2026?

🤖 Context

YES if Météo‑France's official national vigilance map or bulletins show one or more French departments assigned to 'vigilance rouge' for the hazard canicule at any valid bulletin time during July 18, 2026 (France local date), according to Météo‑France, otherwise NO. If Météo‑France issues no vigilance map or bulletin for that date by the resolution time, the market resolves NO. If Météo‑France changes its alert-level names, treat the agency's top heat alert as 'vigilance rouge'.
