Mainland Portugal faces this Thursday the hottest period of the week, with maximum temperatures rising significantly across much of the territory. Thermometers could reach 42 degrees Celsius in some regions of the country.
The hot air mass coming from North Africa brings with it Saharan dust, which should affect air quality in various areas of the territory. The combination of this phenomenon with the high temperatures creates conditions for the occurrence of mud rain.
This episode of extreme heat represents one of the hottest days of the year so far, with special impact on the interior and southern regions of the country. Authorities recommend caution and adequate hydration during this period.
