The heat continues to tighten in Spain. The warm episode that began this Wednesday after a month of storms in large areas of the country intensifies this Friday with another rise in temperatures. The State Meteorological Agency (Aemet) has activated the first heat warnings for the meteorological summer in five provinces in the south of the peninsula.

The agency has activated yellow notices in several provinces of Extremadura and Andalusia for temperatures of up to 38ºC in the Guadalquivir Valley of Jaén, in the Sevillian countryside and Vegas del Guadiana (Badajoz), among other areas.

These are not the first warnings for maximum temperatures of the year, since this circumstance occurred on April 27, when Aemet activated it due to the forecast that La Mancha, Albacete, would reach at least 36 degrees.

For this Friday, a rise in rising temperatures is expected, except in Galicia, the Mediterranean area and the Canary Islands, where they will remain with little change. It will be hotter in Badajoz, Córdoba and Seville (39 degrees), and Ciudad Real, Huelva and Jaén (36), while it will be milder especially in A Coruña and Santander (23), and San Sebastián (25).

Same heat for Saturday, with rising daytime temperatures throughout the eastern half of the peninsula, the Canary Islands and the Balearic Islands; declining in the western half.

However, as of tomorrow, an increase in instability is expected for this day in the northern half of the peninsula, due to the approach of an Atlantic low, which will leave locally strong showers and storms with hail in the surroundings of the Cantabrian mountain range , Iberian system, upper Ebro, Aragon and Pyrenees.

On Saturday the thermometers will begin to drop in the north and northwest, generalizing the declines in the Peninsula on Sunday.

On the other hand, the copious rains of the last week have reduced the accumulated lack of precipitation by four percentage points since the hydrological year began on October 1 until June 13, as reported by the State Meteorological Agency (AEMET).

Thus, from June 7 to 13, the rainfall deficit has decreased from 20 to 16 percent, since the average value of rainfall in Spain as a whole has reached 453 liters per square meter, 16 percent less than the average normal value for this period is 537 liters per square meter.

Despite these amounts, the values ??remain below normal in most of the Peninsula and archipelagos, especially in the northeast quadrant of the peninsula and in the southern half. In many areas, 75 percent of precipitation is not reached, that is, the deficit is more than 25 percent, such as in the northeast and southwest quadrants of the peninsula and in most of the Canary Islands.

On the contrary, they exceed the normal precipitation values ??for the reference period 1991-2020 in areas of Galicia, in the western half of Castilla y León and in the province of Cáceres, in an area between Almería, Murcia and Albacete and between Madrid , Toledo and Cuenca, in the interior of Teruel, in the eastern half of the island of Mallorca, on the island of Menorca and in the southern half of the island of Tenerife.
