The State Meteorological Agency (AEMET) has issued a new special notice for theheat wave which is reaching Spain. It is expected to last from this Friday until Sunday, when the Meteorological Service expects the mercury to peak, with highs above 40 degrees in a good part of the country and possible temperature records.
The weather this Friday
Stable weather is expected on Friday with an increase in maximum temperatures in the western third and in the northeast of the peninsula, as well as in the Canary Islands. The skies will be partly cloudy in almost the entire country except in Galicia, the Cantabrian area, the upper and lower Ebro, the Strait and the Gulf of Cadiz.
Maximum temperatures will tend to increase in the western third and in the northeast of the peninsula, as well as in the Canary Islands, and will remain unchanged in the rest, as will minimum temperatures. Temperatures will continue to reach 35 degrees in most of the interior areas of the Peninsula and in the Balearic Islands, although this will not be ruled out in Gran Canaria, even Temperatures will exceed 40 in areas of the southern plateau, Andalusia, and specifically in the depressions of the northeast.
Where is there a high temperature alert?
Eleven autonomous communities are on alert for the high temperatures that will be recorded this Friday, the first day of a new heat wave. The warning is “orange” (significant risk) in large areas of seven communities, those of Andalusia, Aragon, Castile and Leon, Castile-La Mancha, Catalonia, Extremadura and Madrid, where thermometers will be around 40 degrees during the central hours of the day and in many places will even exceed these values.
The map of the notices is completed with the “yellow” (risk) alerts have been activated in many areas of these communities, as well as in the Balearic Islands, Galicia, Navarre and La Rioja. In all cases, temperatures will be particularly high, around 40 degrees, although Aemet has announced that temperatures will exceed 41 degrees in many parts of the peninsula, including the Tajo valley, in Aranjuez, and the Henares and Jarama basins (in Madrid).
The nights will continue with very high temperatureswithout falling below 20ºC or 23ºC in large areas of the centre, south and east of the peninsula. On the shores of the Mediterranean, the minimum temperatures will be higher and In some places, temperatures may not drop below 25ºC or more.
The worst days of the heat wave
Saturday will be the peak day of the new heat episode. Temperatures are likely to exceed 40 degrees in general in the valleys of the Ebro, Tajo, Guadiana and Guadalquivir rivers; 38-39 degrees in the valleys of the Duero and Miño rivers, the centre of the peninsula, the west of the southern plateau and the Genil basin.
In addition, it is likely that exceed 34 degrees in western Galicia and 36 degrees in the rest of the northern plateau, inland Catalonia, the north of the Valencian Community and the south of the Balearic Islands.
He Sunday It is very likely that a new one will start to enter Atlantic mass, cooleralong the western third of the peninsula, producing a moderate temperature drop but only in this area.
On the contrary, In the Cantabrian area, the south wind will cause significant increases in temperature. With this, sTemperatures will exceed 40 degrees in the eastern Cantabrian region and in the valleys of the Ebro, Tajo, Guadiana and Guadalquivir, without ruling out 42 degrees on the Basque coast and the Ebro valley; 38-39 degrees in the Duero Valley, central peninsula and southern plateau; and 36 degrees in the rest of the territory, except coastal areas.
Storms in these areas
During the weekend there will be a increased atmospheric instability and will increase the likelihood of storms mainly in the area around the Cantabrian mountain range, the Iberian system and the Pyrenees. Given the low humidity, it is likely that the storms will consist mainly of electrical activity and strong or very strong gusts of wind.
((H2:Until what day will the extreme heat last?)
A progressive increase is expected from Monday penetration of the Atlantic air mass into the entire Peninsula, leading to continued drops in temperatures. The values reached from this day onwards, although high, will be more typical of summer and will most likely not meet the criteria for a heat wave.
