A few days ago we talked about how a corridor had opened between the Azores anticyclone and Iceland depression. Moreover, we argued how Spain had many options for become the great beneficiary of that trough.
Well, we sin of optimists. Just look at heaven to realize that this is never to end.
What happened? In the next few days, there are two structures that walk the time of the peninsula. On the one hand, a cold front has been slowly moving through the west of the Iberian Peninsula. On the other, a Dana has traveled the south coast from the Gulf of Cádiz to the heart of Algeria.
As the meteorologist Ángel Rivera explainedwhat we see is the result of the closure of that wide historical trough.
And it will happen again. Right now, there is an “extensive cold storm” in the Atlantic corridorbut it doesn’t seem to affect us. Because just southwest of this, a dorsal begins to gain strength and will end up moving towards Europe.
And all that without counting the anticyclonic wall that is beginning to develop between the Canary Islands and the mouth of the Cantabrian; and that, as a direct consequence, it will generate a Dana that will cross the Gulf of Cádiz and (as far as we can predict) will also go to North Africa.
That is, again and again, the chances of rain arriving in Spain are frustrated. What he said: the never ending story.
What time will it do? Aemet’s forecast is very clear. From Monday to Wednesday, the most important thing will happen in the Canary Islands: with very strong wind gusts and notices. Galicia can also suffer some timing, but the rest of the peninsula will only see some occasional showers.
On Thursday it will be a sunny day and during the weekend we will see how that front of which we have spoken will sweep the peninsula leaving some rain. On Sunday the sun will return. In general, temperatures will be more of spring.
And that is the problem. We already carry two warm winters (No cold waves or intense cold episodes) And the rain is being as erratic as usual. That places us in a complex situation: before we realize, the drought will be knocking on our door.
The best example is The Sau reservoir, in Barcelona: A swamp that “despite the latest rains (…) shows a lousy state, with just 8% of its water flow.” It is a notice to navigators: the Ter-Llobregat system, the Segura basin or the Andalusian Mediterranean basins They are already having a bad time. The good weather is, deep down, a conviction. Spring for today, but thirst for tomorrow.
