Almost all of France will be affected in the coming days. The east and south-east of the country should experience the highest densities from this Sunday, April 28.
He is making yet another return to France. The sand from the Sahara will settle into the atmosphere on Sunday and Monday, a few weeks after passing over France.
Dust from the African desert will come from the south-east of the country before going north. On Monday, all regions will be affected, except Brittany and the English Channel which should be spared.
The highest concentrations will be felt in the South-East on Sunday. They will move towards the north-east of France on Monday. Note that the sand could remain in the air for several days before leaving the atmosphere.
Is this air dangerous for health?
While it is not harmful to ordinary people, this air laden with desert sand can be dangerous for young children, the elderly, those suffering from respiratory problems or even allergies.
Concretely, the density of particles coming from the Sahara is similar to that recorded during pollution peaks. It is therefore recommended to limit outdoor physical activities.
How to explain the phenomenon?
How can sand from the Sahara reach France? Météo-France explains it in a graph published on social networks. First, the wind lifts the particles in the north of the African continent. Then, a disturbance located above Spain will pump this air. Reversing its direction of rotation will allow it to cross the Mediterranean and reach France.
Finally, the arrival of rain in several regions crossed by this cloud will cause the dust to fall. This is why sand particles may land on your vehicles.
