The IPMA also placed many municipalities in all districts (18) of mainland Portugal at very high and high fire risk.
According to the IPMA, at least until the end of the week, the risk of maximum and very high fire in several counties on the continent will remain due to the hot weather.
The fire risk 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.
On the continent, the IPMA forecasts little cloudy or clear skies, presenting periods of greater cloudiness on the west coast and in the interior of the southern region until mid-morning.
During the afternoon, an increase in cloudiness is expected in the northern and central interior regions with the possibility of showers, occasionally hail and accompanied by gusts and thunderstorms.
A light wind is also expected, becoming moderate and predominating in the northwest from the afternoon, sometimes blowing strong with gusts up to 60 kilometers per hour in the western coastal strip and in the highlands.
The forecast also points to morning fog or fog in some places on the west coast and a rise in maximum temperature, except in the northeast of Trás-os-Montes and in the eastern Algarve, being accentuated on the north coast.
The minimum temperatures will vary between 14 degrees Celsius (in Évora and Beja) and 20 (in Bragança) and the maximum between 23 (in Aveiro) and 36 (in Évora).
Because of the hot weather, the National Authority for Emergency and Civil Protection (ANEPC) on Monday decreed the passage of 10 districts, mostly in the interior, to the state of special orange alert due to the risk of very high or maximum rural fire.
ANEPC, through its national command, decreed the transition to the state of special orange alert for the following districts: Beja, Bragança, Castelo Branco, Évora, Faro, Guarda, Portalegre, Santarém, Vila Real and Viseu ”.
At the origin of the hot weather is “an anticyclone located over the Azores region, which extends along the ridge to the Bay of Biscay, together with a depression centered in the interior of the Peninsula and the approach of a valley in altitude, which originate the transport of a mass of hot air from North Africa with instability in the interior and temperature rise in the coming days ”, according to IPMA.
The yellow special alert status is maintained for the remaining districts of the country
