A new cloud of sand from the Sahara
A question arises with these forecasts: should we fear a new cloud of sand from the Sahara in Belgium?
According to forecasts by the Copernicus Atmosphere Monitoring Service (CAMS), a new cloud of dust from the Sahara is heading towards Europe. The large cloud is currently traveling over the Atlantic Ocean and will reach Portugal and Spain this weekend as well as several regions in western France.
Significant quantities of sand from the Sahara have already been recorded this year by CAMS services. The phenomenon, which occurs several times a year, gave a reddish tint to the Belgian sky a few weeks ago before settling on cars, windows and garden furniture.
