The sky is likely to turn a little yellow today. The first big wave of dust from the Sahara of the year is indeed expected and should reach France this Wednesday according to forecasts from the Copernicus atmosphere monitoring servicebefore continuing further north to Denmark.
“Predictions also show elevated concentrations of PM10 at the surface for Spain and at higher altitudes, for example in the Pyrenees and the Alps, which could lead to dust deposition on the surface in these areas,” says this service of the European Center for Weather Forecasts.
And as precipitation is announced during the day, it could be loaded with sandy particles. This dust, which comes up regularly at this time of year, is a source of pollution and can have health effects. In particular, they aggravate allergic symptoms due to irritants, as well as respiratory problems. But the concentrations of this Wednesday, January 22 should be less important than those of last year.
