The districts under yellow warning are Vila Real, Bragança, Viseu, Guarda, Castelo Branco, Santarém, Lisboa, Setúbal, Portalegre, Évora, and Beja. The warning takes effect at 9 AM tomorrow, September 3rd, and ends at 6 PM on Friday, September 4th.

The remaining districts, which are part of the North and Central coastal strip and Faro, are exempt from any warning, due to a more contained temperature rise forecast for those regions.
