Certain areas like Girona, Tarragona and Barcelona have recorded up to 100 mm of rain in an hour. The red alert in Catalonia has been lifted. It is the turn of the south of France to be threatened. Météo France has issued orange and red alerts. A warning sign of a rotten summer this year in the Mediterranean basin? “For Spain, there is no longer much to fear for the next two weeks”says Pascal Mortmal. “”Summer will be hot to very hot, even in Belgium “.”
More intense phenomena
The Mediterranean basin retains its characteristics in the climate. No more cold drop phenomenon predicts a priori. “”The biggest concern for the Mediterranean basin this summer is not the rain but it is the forest fires because the whole south continues to overheat “underlines the meteorologist.

The phenomenon of cold drop is quite classic especially during the off -season in the fall and spring. The Mediterranean Sea is increasingly hot and the air is cold at altitude. The contrast between the two air masses creates instability and thunderstorms stuck in the relief which causes precipitation. More generally, Europe is experiencing more intense weather phenomena in recent years.
“The episodes of very intense rains interspersed with very intense drought episodes are likely to multiply. We already have signals in Belgium: the threshold of 20 mm of rain is more and more frequently reached that 20 years ago but the annual totals will not change. We will never have a Mediterranean climate with us”finishes Pascal Mortmal who recommends avoiding concrete of floors and encourages to greening a maximum with hedges and trees so that they retain the soils more.
