Almost all of Spain will be at risk this Wednesday due to heat, storms and waves, on a day marked by significantly high temperatures in a large part of the country that will reach 42 degrees (ºC) in the Basque Country, with the possibility of a locally strong storm in the Pyrenees and intervals of strong wind in the Strait, according to the prediction of the State Meteorological Agency (AEMET).

Specifically, the heat will activate the warnings in Almería, Cádiz, Granada, Mallorca, Menorca, Ibiza and Formentera, León, Palencia, Segovia, Soria, Castilla-La Mancha, A Coruña, Lugo, Pontevedra, Madrid, Castellón, Valencia, Gran Canary Islands, La Gomera, El Hierro and Tenerife.

The risk due to heat will rise to significant in Córdoba, Huelva, Jaén, Seville, Aragón, Asturias, Cantabria, Ávila, Burgos, Salamanca, Valladolid, Zamora, Barcelona, ​​Gerona, Lérida, Tarragona, Extremadura, Ourense, Navarra, La Rioja. In addition, the Basque Country will activate extreme risk (red notice) for maximum temperatures of up to 42ºC.

On the other hand, the waves will put Cádiz at risk and the storms will give Huesca, Barcelona, ​​Girona and Lérida an important warning.

Thus, this Wednesday, in most of the country, slightly cloudy or clear skies with high clouds will predominate, except for low morning clouds on the coasts of Galicia, the western Cantabrian Sea, the Strait, Melilla and the Balearic Islands, without ruling out some morning precipitation in the north of Galicia.

In the afternoon, abundant evolutionary clouds are expected in large areas of the northern interior third, with possible scattered showers and storms, more likely in the mountains, especially in the Pyrenees environment, where they can be locally strong.

In the Canary Islands, there will be cloudy intervals and abundant medium and high cloudiness, without ruling out a shower or storm in the higher relief.

There will be possible banks of morning fog on the Galician, Cantabrian and Strait coasts, as well as high haze in the Canary Islands.

Minimum temperatures will increase in the northwest third of the peninsula and west of Andalusia, with increasing maximum temperatures in the extreme north, which will be notable in the Cantabrian Sea and even extraordinary in the Basque Country. No big changes are expected in the rest.

In this way, it is expected to reach 34-36ºC in practically the entire interior of the peninsula and the Balearic Islands, including 38-40ºC in a large part of the Atlantic slope, depressions in the northeast and inland Cantabrian.

The wind will blow from the Levant in Alborán and, with strong intervals, in the Strait. Northeast winds are expected on the northwest and southeast coasts and in the rest there will be light winds, from the north in the Canary Islands, from the southeast and south at central hours in much of the interior of the peninsula and variable in the rest.
