The Weather in El Español for this Monday, September 7.

As reported Ruben del Campo, spokesperson for the State Meteorological Agency (Aemet), the DANA -also known colloquially as Cold drop– and the high atmospheric moisture content over the Mediterranean Sea They make it rain intensely in the Balearic Islands and parts of the eastern peninsula, especially in the north of the Catalan coast.So much so that, according to data provided by Aemet, between 07:00 am on Sunday morning and 07:00 am this morning, more than 63 liters per square meter have been collected in Andratx (Mallorca) or 62 liters per square meter in El Prat (Barcelona), of which 50 fell in just one hour with a strong intensity that also occurred in other parts of the city.The Aemet warns that a DANA “is not synonymous with catastrophic rains”, despite which the General Directorate of Civil Protection and Emergencies has issued a statement advising exercise extreme caution in the Mediterranean area and the Balearic Islands from today until next Wednesday.Among other recommendations, Civil Protection warns that if it starts to rain in a torrential way there is a risk of flooding and, therefore, the flooded sections should not be crossed by vehicle or on foot, it is necessary to stand at the highest points of the area and never try to save the car in the middle of a flood.They also advise that if we are in the countryside, we must move away from rivers, streams and low areas of slopes and hills and that, in the event of a storm, it is advisable to stand under buildings to protect ourselves from lightning.

More DANAs for climate change?

Among the many effects that Spain may suffer from the global warming is that of a increased risk of torrential rains in the Mediterranean.

The temperature of the Mediterranean Sea increases at the end of summer and this acts like trigger of storms and torrential rains when a DANA arrives.

Keep in mind that the sea temperature is increasing with 0.8ºC in the last 100 years on the Spanish Mediterranean coast and with a very accelerated rise since 1980. All this in a process of heat accumulation in the spring months and that lasts in summer until well into autumn (October and early November).

According to climate change projections for the next decades, the Mediterranean temperature will continue to rise. This makes it easier for stormy clouds to form and for the rains to concentrate in a shorter period of time, being able to discharge between 100 and 200 liters per square meter in just one hour.

What’s more, cold drops are no longer a phenomenon of autumn to be present nine months of the year, from the beginning of spring to the end of fall.
