Today's warnings correspond to half of those in orange on Saturday, as the IPMA predicts a drop in maximum temperatures on the west coast.

The lull in temperatures along the coast precedes a new rise in temperature in the coming days, which has led the Government to declare a contingency situation between Monday and Friday, due to the increased danger of fires.

The increase in that risk led the President of the Republic, Marcelo Rebelo de Sousa, and the Prime Minister, António Costa, to cancel trips to the United States and Mozambique, respectively, to monitor the fire situation in Portugal.

Under an orange warning are today the districts of Vila Real, Bragança, Viseu, Guarda, Castelo Branco, Portalegre, Évora and Beja, as well as the Mountainous Regions in Madeira.

The yellow warning is valid for Viana do Castelo, Braga, Porto, Aveiro, Coimbra, Leiria, Santarém, Lisbon, Setúbal and Faro, as well as for the North and South Coasts of Madeira.

Maximum temperatures will fluctuate between 42 degrees Celsius in Évora and 24 degrees in Porto and Aveiro.
