1. If you think #valencia is out of the woods, think again. The cut-off low that pulls humid air from over the meditteranean across the mountains north of Valencia is not done yet. In the coming 2 days the @kachelmannwetter multimodel ensemble predicts up to 177 mm of extra rain in the region of #castellon .

Not only #Spain but the entire #EU will have to have a difficult conversation on how we'll prepare us for #weather #disaster amplified by #ClimateChange

A thread.

2. Not just the past days, but the whole summer the temperatures in the Mediterranean were warmer than average. Due to the extra evaporation, this gives a bunch of humid air hanging around above the mediterranean.

3. A low pressure area is circling in front of the coast of Portugal, and that circulation drags all this moist air over the mountains surrounding Valencia. In the satellite images you can see a plume of very cold and wet air rise right above Valencia. This is caused by the wet mass of air above the mediterranean that is dragged over the mountains by the circulation west of Portugal. Quickly rising air cools down, and this causes the intense rains.

Step one: Ban all right-wing parties.
