sand on snow in sierra nevada spain

In late February 2017, strong winds from Africa brought sand from the Sahara desert to Europe, notably Spain, Italy and France.

The sand moves in the form of fine particles in the atmosphere the phenomenon is call Sirocco.

Many persons have captured images at many ski resorts in Europe, but where the phenomenon is most visible across Europe, it is undoubtedly in Sierra Nevada not far from Granada in the south of Spain.

Here is the picture before the arrival of the sand (see after the same image but with sand !)

Indeed in some places we even have the impression that there is more sand that snow !

So skiing on snow or off-piste under the sand in Sierra Nevada ?
