The dust of the Sahara is back.
Friday, from 5 p.m., high winds loaded with sand from the Sahara will blow from the Bay of Biscay on the south-west of the country before heading towards Bordeaux then towards the east and the center of France. .
These are forecasts from the satellites of Copernicus, the European Union's Earth observation program, reports

A phenomenon that could intensify
“If thunderstorms occur Friday and Saturday, there could be deposits on the ground.
In the past, we knew that they had flown over France when we saw a layer of red sand on our cars, but our ability to predict their arrival has improved significantly, "explained Vincent-Henri Peuch, the director of the surveillance service of the atmosphere of Copernicus.
Already more and more frequent, this type of phenomenon could continue to intensify in the future due to global warming leading to recurring droughts and ever greater desertification of our planet.
If it can delight the eye of some photographers when the summits take on a tint of yellow sand, this phenomenon poses serious problems, whether on health, air traffic or melting snow.
But this dust can also have a certain utility because it “plays a role in the formation of clouds, acting as a nucleus around which water particles aggregate”, according to European specialists in the observation of the atmosphere.
