The arrival of an Atlantic storm clearly changes the weather in Spain and activates warnings from the State Meteorological Agency (AEMET) given the forecast of intense storms, locally heavy rainfall and significant wind gusts in a good part of the peninsular west.
The episode will begin to be noticed with greater intensity from Tuesday, when the frontal system advances over the Peninsula and leaves a scenario of instability that will especially affect Castilla y León, Castilla-La Mancha, Extremadura and Galicia. In these areas, AEMET maintains yellow warnings for accumulated rainfall and storms that could be accompanied by hail.
Intense rains, hail and strong wind: the most affected areas
Forecasts point to significant rainfall in the vicinity of the Central System and the peninsular west, with notable accumulations in short periods of time. Storms are also not ruled out in western Andalusia, within a more irregular but equally unstable pattern.
To this scenario is added the wind, with gusts that can exceed 70 km/h in areas of the Cantabrian Mountain Range and Extremadura, which increases the impact of the episode, especially in exposed areas.
Suspended dust and mud rains: the other key factor
Another element to take into account is the presence of suspended dust in the center and west of the Peninsula. The combination with precipitation can cause mud rains, a common phenomenon in this type of atmospheric situation and that affects both visibility and air quality.
Canary Islands and the peninsular east: more contained evolution but with changes
In the Canary Islands, the passage of the system will leave more cloudy skies in the mountainous islands, with precipitation in the north from the afternoon, while in the rest of the archipelago cloudy intervals will prevail.
In the eastern half of the peninsula and the Balearic Islands, the impact will be minor, although abundant clouds, mists, and possible fog banks are expected in areas of the Mediterranean coast.
Drop in temperatures and change of trend
The storm will also bring a drop in maximum temperatures in the peninsular west, where the drop can be notable, while in the east the changes will be milder.
Minimums will tend to rise slightly in some areas, in a context of transition towards a more unstable weather pattern after several days of stability.
