Will one or more metropolitan French departments be in 'vigilance rouge' (red alert) for a heatwave?

Warum: Contemporaneous official and mainstream French reporting for 8–9 August 2026 show departments placed in vigilance orange for canicule; none of the supplied sources report any metropolitan department being placed in vigilance rouge for heatwave during that window. Météo‑France’s site (last update 08/08/2026) displays the national vigilance as orange, and independent outlets (TF1, 20 Minutes, La Croix, actu.fr) for 8–9 August list specific departments in vigilance orange for canicule without any mention of a vigilance rouge on those dates. The only references to vigilance rouge in the evidence refer to earlier episodes (e.g. the AA piece citing 12 July) or come from a non‑authoritative blog; those are outside or not corroborated for 8–9 August. Because the official Météo‑France bulletin and multiple independent news outlets contemporaneously record only orange alerts for 08–09 Aug 2026, there is positive evidence that no mainland French department was placed under vigilance rouge for heatwave in that period.
