The danger of fire risk will remain high in some regions of the continent at least until Saturday.

Eight municipalities in the districts of Faro, Portalegre and Santarém present maximum fire danger today, according to the Portuguese Institute of the Sea and Atmosphere (IPMA).

At the highest risk of fire are the municipalities of Tomar, Vila Nova da Barquinha, Abrantes, Sardoal (Santarém), Gavião (Portalegre), Loulé, São Brás de Alportel and Tavira (Faro).

The IPMA has also put more than 40 municipalities in Faro, Beja, Leiria, Coimbra, Santarém, Portalegre, Castelo Branco, Guarda, Viseu and Bragança at very high danger.

This fire hazard, determined by the IPMA, has five levels, ranging from reduced to maximum.

The calculations are obtained from the air temperature, relative humidity, wind speed and amount of precipitation in the last 24 hours.

The IPMA forecasts for today on the mainland a generally clear sky, with periods of greater cloudiness until early morning on the North and Central coast and a small rise in minimum temperature.

The minimum temperatures will fluctuate between 11 degrees Celsius (in Bragança) and 19 (in Faro) and the maximum between 21 (in Aveiro, Porto and Viana do Castelo) and 34 (in Faro).
