The sand travelled all the way from the North of Africa, covering more than 2,000 kilometres in less than 24 hours. A dust cloud was formed at a big altitude due to a desert storm, after which strong southerly pushed the cloud across Spain and France to our region.
When it started raining yesterday afternoon, the drizzle brought down the dust, covering the whole area with a thin layer of dust. This could of course best be noticed on cars. It's not exceptional that this happens, but the size of the dust cloud is quite exceptional this time.
The dust cloud next moved on to the Netherlands.
