Eighteen municipalities in the country are in very high danger of fire this Wednesday, according to the Portuguese Institute of the Sea and the Atmosphere (IPMA).
The IPMA also placed more than 50 municipalities in the districts of Bragança, Castelo Branco, Santarém, Leiria, Lisbon, Setúbal, Évora, Beja and Faro at high risk.
Almost all of the rest of mainland Portugal is in moderate danger of fire, with the exception of some municipalities on the north coast and in the interior of the districts of Viana do Castelo, Porto, Vila Real, Coimbra and Leiria, as well as the municipality of Vila do Bispo, in the district of Faro, which present a reduced danger.
The fire hazard, determined by the IPMA, has five levels, ranging from reduced to maximum. Calculations are obtained from air temperature, relative humidity, wind speed and amount of precipitation in the last 24 hours.
