The Meteorology Statal Agency (AEMET) anticipates a notable increase in the climate instability in the Peninsula this Saturday, particularly in the northwest region, due to the imminent arrival of a small Isolated Depression at High Levels, commonly known as DANA. This phenomenon implies the presence of a mass of cold air that has broken away from the main current, which could cause precipitation and storms. In relation to temperatures, it is projected that the maximum values will experience an increase on the Mediterranean slope, while a decrease is expected in the northwest and in the Canary Islands.
On the other hand, the minimum temperatures will generally show a Upward trend, with the exception of the Canary Islands where a decrease is expected, and on the northwest and southeast coasts where no significant changes are expected. Teruel will record the lowest temperature with 7°C, and it is likely that some weak frosts will be observed scattered on the peaks of the Pyrenees. Temperatures will exceed 30 degrees in the Guadalquivir and middle Ebro valleys, indicating that it will be a fairly hot day in these regions. Seville, for its part, will register the maximum temperature highest with 33°C.
With the arrival of small DANA, the northwest region of the Peninsula will experience an increase in meteorological instability. The sky panorama will be characterized by the presence of intervals of high clouds along with medium clouds that will move towards the northeast. Likewise, the formation of evolution clouds is expected throughout the day, which can give rise to storms in much of the interior.
On the northern plateau and its surroundings, as well as on the peaks of the Pyrenees, a increased cloudiness, which could result in showers and storms. These phenomena can be particularly intense in the Cantabrian, upper Ebro and northern Iberian and northern plateau. It is not ruled out that they may also occur in isolation in other areas of the Plateau, in the southeastern mountains and in the extreme northern interior.
In the Balearic Islands A mostly clear sky is expected. However, in Canary Islands, periods of cloudiness are expected in the northern areas of the islands with higher altitudes, while in the rest a predominantly clear sky is anticipated. It is possible that persistent coastal fogs will occur on the northern coast of Galicia and on the western Cantabrian coast, which could reduce visibility. The AEMET warns about the possible presence of haze or suspended dust in the autonomous city of Melilla.
Finally, it is expected that the prevailing winds blow from the east in the eastern half of the Peninsula and in the Balearic Islands. In the western half of the Peninsula, winds will initially be light and variable, but are expected to change to westerly and northwesterly winds in the north, and southerly winds in the southern half, generally gentle. In the Canary Islands, the main wind will be the trade wind, a constant wind blowing from the northeast, with some periods of strong intensity.
