Aemet emits the first orange warnings by extreme temperatures

A few days ago, meteorologists They foresee that the worst of the warm episode that affects the Iberian Peninsula would come from Wednesday. Well, we are on Thursday and the forecasts become facts: the “Iberian oven” has activated and with it preventive measures.

Orange warnings. Heat has led to the State Meteorology Agency to issue A series of yellow and orange notices by maximum temperatures. Today’s notices will affect seven autonomous communities, tomorrow Friday to nine. The Sevillian countryside will be the most affected area, where notices will be oranges due to maximum temperatures of 40º Celsius.

Oven ignition. The obvious question is what is happening for the sudden arrival of more typical temperatures of summer than at the end of May. The answer can be found in the phenomenon known as “Iberian oven”

As details Marta Almarcha in eltiempo.esthe phenomenon begins with the appearance of a dorsal in middle and high layers, that is, in the prolongation of a high -pressure center. This implies atmospheric stability and air -descendant movements that compress and heat the air mass over our own heads.

More than an anticyclone. Anticyclonic and stable time also contributes to a High insolation which in turn also implies heat. As if this were not enough, Aemet warned a few days ago of the irruption of a Dana located between the Canary Islands and the Gulf of Cádiz that since yesterday pushes warm, dry and with dust in suspension to the peninsular south.

Heat, very heat. The result, the one that is well palpating: heat. According to them Aemet forecaststoday maximum “high temperatures are expected for the time in most of the Peninsula”, with areas of the South exceeding the 34º-36º and with the possibility of exceeding 38º-40º in the Guadalquivir and Guadiana Extremadura.

The story will be similar tomorrow Friday, with high maxims, possibility of exceeding 34º-36º degrees in the southern Atlantic aspect and the 38º-40º in the Guadalquivir, but without ruling out that the thermometers also reach this temperature at points of the Guadiana and depressions of the northeast. On Saturday a similar situation will be repeated as far as the maxims are concerned.

Tropical nights. In addition to the maximum, the minimum temperatures also concern many. The fact that night temperatures They are not going to get off the 20th In some areas the dream of many will make it difficult. This is the phenomenon known as “tropical nights.”

Spring activation. It is not the first time that we see this “Iberian oven” be activated in the middle of spring. In 2023 without going any further We were talking of its possible activation at the end of April.
