Until the 6th of August, next Monday, the maximum air temperature in most of the mainland territory, will register values in the order of 40°C, but, from tomorrow until Saturday, in what will be «the most critical period», in several places in Alentejo, in the valley of the Douro and Tagus rivers and in Beira Baixa, «the maximum temperature may reach 45°C and, in a or elsewhere, exceeds this value'.
The new alert has just been released by the Portuguese Institute of the Sea and the Atmosphere (IPMA), which announces that "the minimum temperature values will also be very high, reaching values close to 25°C in a large part of the territory", but approaching up to 30°C «in some places in the interior of the Center and South, especially in Alto Alentejo».
In order not to say that this never happened, IPMA recalls that «this meteorological situation is comparable to the meteorological situation of August 2003 in Mainland Portugal».
In that heat wave of 2003, «there were also very high values of the minimum and maximum temperature, setting a new absolute maximum relative to the maximum temperature, at 47,3°C, in Amareleja, on 1st August " this year.
IPMA also announces that, after this new situation of extreme heat, “from the 6th, the temperature will decrease in the west coast regions and gradually in the interior regions in the following days, but maintaining values of the order of 35°C or more, in many inland locations by the end of next week.
That organism also draws attention to the "transport of dust from North Africa", which is already affecting the southern region as of today, on the 1st of August, «translating into a yellowish hue in the sky».
«Taking into account that, in general, the thermal comfort zone is located between 18° and 26°C (relative humidity between 30 and 70%), the extreme heat forecast for the period from 2 to 6 August will lead to a situation of great thermal discomfort», concludes the IPMA.
