The rains in the Mediterranean have arrived at a very delicate time for the reservoirs of the region

The Mediterranean basin is living a new episode of heavy rains. The extreme of the episode led yesterday to the State Meteorology Agency (AEMET) to Issue several red notices For extreme risk, while numerous yellow and oranges notices remain in force today. Despite the obvious risk that this is, there is the circumstance that rainfall arrives at a delicate time for one of the hydrographic basins of the region.

The arrival of the rains. The Mediterranean basin rains They monopolize the looks of meteorologists. Aemet today maintains several notices associated with storms and rainfall in much of the eastern coast, notices that also cover interior provinces. Notices that, during the morning they will still remain in the Balearic Islands.

A delicate moment in the safe. After several years of drought, almost a year of high rainfall between autumn of 2024 and Spring of 2025 served to allow most of the country’s hydrographic basins to recover water. Many even saw unprecedented filling levels in years.

This It wasn’t exactly The case of the Segura Basin. The state of The reservoirs of this basin From southeast peninsular improved with respect to 2024, but did not reach the filling level of 2023 or its average of the last 10 years.

Such is the situation, that a few days ago, the Segura Hydrographic Confederation He pointed out that the scarcity index index had crossed the threshold of the pre -alder and was approaching the border of the alert situation.

A dry August. Except in some specific areas, August has been A dry month on the peninsula (Not so much in the island communities), even by this point of the year. Precipitation in peninsular Spain were around 34% lower than those that could be expected for a month of August, and that has been noted in the water reserve.

The Spanish reservoirs went from being, on average, 67% of its capacity At the end of July to be at 59.3% At the beginning of September. Of course, summer is a time when Reserve descent Water is expected, but weather has not helped stop this trend.

In the case of the Safe Basin, the Last data availablethose of last week, indicate that the reservoirs of this environment are found at 22.5% of its capacity, making it the dry basin in the country. It is also at a distance from the next, that of Guadalete-Barbate, which was last week to 44.5% of its capacity.

We will have to wait. One of the areas where orange notices have been issued for important risk is precisely that of the Vega del Segura, in Murcia, where they are expected 30 mm accumulated in an hour. Other areas of this basin have also seen yellow or orange warnings are activated during yesterday and today.
