The weather is relentless in Spain this May, and instability continues to dominate the meteorological landscape. This scenario will continue throughout the week, as a persistent anticyclonic blocking in the vicinity of the British Isles which favours the arrival of DANAs, pockets of cold air at altitude that will continue to affect the weather.
In the coming days, several cold air drops will alternate over the country, creating what many experts already call a authentic “DANAs dance”. The consequences will be a succession of storms, intense rain with hail, and sudden temperature changes, affecting much of the country.
The start of the week: first heavy rains and widespread showers
The weather situation, which has been changing rapidly these days, will begin with the approach of the DANA (High Winds), which has been affecting the area for several days. This phenomenon could also interact with another depression forming off the southern coast of the peninsula, increasing instability on the Peninsula.
Heavy downpours are expected in parts of the Balearic Islands, Catalonia and the Pyrenees on Monday and Tuesday. as well as in the northern and eastern half. In parts of Galicia and the Cantabrian Sea, rainfall could be intense and locally accompanied by storms; in the Canary Islands, the approach of a low water level will also cause occasional heavy showers.
La The influence of DANA will be felt from the early hours, with showers in the northern third, especially in the Pyrenees, Navarra and La Rioja, while in the afternoon storms in the eastern interior, Pyrenees, eastern Cantabrian and areas of the Balearic Islands. These precipitations may be accompanied by hail and strong gusts of wind in several communities.
Wednesday and Thursday: the epicenter of the storms
Models predict that the instability will reach its peak midweek, especially on Wednesday and Thursday. In this phase, the Peninsula and the Balearic Islands will be at the center of the action of several DANAs that will alternate, generating extensive and locally very heavy thunderstorms, with the possibility of adverse phenomena such as hail and gales.
It is expected that Storms are expected to be especially concentrated in the eastern part of the peninsula, the Pyrenees, Navarre, La Rioja, and the interior of the Valencian Community and Aragon. La AEMET has activated yellow warnings for heavy rains., hail, and strong gusts of wind in up to ten autonomous communities. Rainfall records may exceed 30 liters per square meter in one hour.
Other notable effects will include high lightning strikes, hail of over two centimeters, and uneven rainfall over short distances. In some areas, such as the eastern and northeastern interior of the peninsula, accumulations of between 40 and 60 liters per square meter are not ruled out. This situation requires extreme caution in areas traditionally vulnerable to flash flooding.
In the rest of the country, rainfall will be less intense, but scattered light showers are possible, especially in mountainous areas and on the archipelagos.
The weekend could bring some stabilization and a thermal rebound.
As the week progresses and Friday approaches, a low anticyclone ridge is expected to cause a rise in temperature and some atmospheric stabilization. However, Scattered thunderstorms may still be recorded in the north, east and the Balearic Islands, although with less intensity and frequency than previous days.
The temperatures, which For much of the week they will remain below the usual average Due to the influence of polar air and various fronts, they will tend to return to normal gradually. However, the possibility of a new DANA arriving on Sunday across the Atlantic uncertainty remains about the continuation of instability for the beginning of next week.
Therefore, it is advisable to pay attention to weather updates and possible warnings for adverse weather conditions, as the volatility and variability of the weather during these days may entail risks associated with heavy rain, thunderstorms, and hail.
