As of today, Monday, the BORRASCA JANA It will lose strength. But that does not mean that Aemet Go withdraw your notices by rains in half a country. And it is that the high -impact formation will continue with us generating instability, cloudy skies and generalized rainfall.
Although, in reality, this seems only the beginning.
Rain, rain and more rain. Although the eastern facade of the peninsula continues with His particular viacrucis (Especially in Alicante), the screws seem to have changed in the rest of the country: the largest accumulated will be in the south, both in the Atlantic and Eastern Andalusia aspect. Also in the central system. On the contrary, where the rains are less likely it is in the Cantabrian and the Northeast.
In the Canary Islands there will be cloudy skies and scattered showers.
But this will have an end … right? Of course he will have it, the problem is that we do not know when it will be. Jana is going to weaken And that, perhaps, we give us a little respite. But, as Aemet points out, “the rain will continue during the week of March 10 to 16”.
After the borrasca jana“new fronts associated with Atlantic storms will sweep our country, with rainfall in large areas.” Again, the most abundant seems to be in the environment of the central and west system of Andalusia.
How is this possible? A few days ago we counted that It was being established A huge blocking anticyclone between Greenland and Scandinavia. That was very good news because I was going to force the Atlantic storms to turn south.
To this has been added something else: that the temperature of the surface water of the ocean is above the average and, thanks to the joint work between the blocking anticyclone and that of the Azores, an atmospheric river has been articulated that insuffes us with moisture from the Caribbean.
The result is 10 days of generalized rains. That is to say, An unusually wet March.
Is something of Holy Week know? This year, Holy Week falls between April 13 and 21. That is, there is a lot of time left. However, Aemet has published A climatological analysis. Unlike the predictions, what this type of analysis is investigated is the “standard time” for those days taking into account the historic.
For example, According to the agency“In most of the southern peninsular half the average temperatures vary between 13 and 17 ºC” while “in the northern half we find lower values, with temperatures near the 9 ° C on the plateau and close to the 0 ºC in the summits.”

The problem is that, as we can see in the superior graph, these “spring dates are characterized by their great climatic variability.” In recent years, temperatures have been high and, a priori, it is what we should expect. But there we have the year 2012 to show us that the situation can turn around when we least expect them.
