Orange-tinted snow has swept across Russia, Bulgaria, Romania and other countries in eastern Europe.
Ski resorts resembled sandy beaches after turning orange while several witnesses said the scenes looked ‘apocalyptic’ and compared it to the surface of Mars. However, there is no cause for concern.
Experts from the Sochi Centre of Hydrometeorology and Monitoring of the Black and Azov Seas say that the cause of the phenomenon is winds carrying sand from the Sahara, which then fell as rain. They predict the snow will return to normal within days.
