Around 90 counties in the interior of Portugal and the Algarve are today at maximum risk of rural fire, namely in the districts of Vila Real, Bragança, Viseu, Coimbra, Guarda, Castelo Branco, Leiria, Portalegre and Faro, according to the IPMA.
The Portuguese Sea and Atmosphere Institute (IPMA) has also placed around 90 municipalities in the districts of Braga, Porto, Aveiro, Coimbra, Leiria, Lisbon and Beja in very high danger.
Other municipalities, especially in the Alentejo and on the north and central coasts, are now in high danger of fire.
Because of the weather conditions, the fire danger will remain high until at least Tuesday.
This risk, determined by the IPMA, has five levels, ranging from low to maximum, and the calculations are based on air temperature, relative humidity, wind speed and the amount of rainfall in the last 24 hours.
The IPMA forecasts slightly cloudy or clear skies on the mainland today, with periods of greater cloudiness in the north and center, strong wind on the west coast and in the mountains and a slight drop in temperature.
The minimum temperatures range from 09 degrees Celsius (Guarda) to 18 (in Setúbal) and the maximum from 22 (in Guarda) to 30 (in Faro).
