Will fewer than 20 metropolitan departments be orange for heatwave on August 4?

🤖 Context

YES if Météo‑France's official vigilance map for metropolitan France published for the date August 4, 2026 shows strictly fewer than 20 departments coloured "orange" for heatwave ("canicule"). Otherwise NO. Count only metropolitan departments as shown on that official map. If Météo‑France publishes multiple maps for that date, use the first official map, and count a department as orange if any part of it is coloured orange.
