People in Russia, Bulgaria, Romania and other Eastern European countries are baffled at the sight of what appears to be orange-tinted snow. 

Pictures of the snow have been going viral on social media including from skiers at a resort near Sochi, a city in Krasnodar Krai, Russia, located on the Black Sea coast. 

According to meteorologists, the bizarre sight is reportedly a result of sand and dust stirred up and carried into the atmosphere from storms in North Africa, before being deposited in the region. 

Steven Keates, of the Met Office, the United Kingdom's national weather service told the Independent : “There has been a lot of lifted sand or dust originating from North Africa and the Sahara, from sandstorms which have formed in the desert. As the sand gets lifted to the upper levels of the atmosphere, it gets distributed elsewhere."

“Looking at satellite imagery from Nasa, it shows a lot of sand and dust in the atmosphere drifting across the Mediterranean. When it rains or snows, it drags down whatever is up there, if there is sand in the atmosphere.”

This is not the first time that a phenomenon like the orange snow has occurred. 

In February 2007, residents of several Siberian towns also experienced the orange snow. The people from the town complained the snow that was malodorous and oily to the touch. It was also reported to contain four times the normal level of iron. When tests were carried out on the snow, it was revealed that it contained various sand and clay dust particles after which Russian officials warned all the residents to not touch the snow or feed it to their animals. 

It was feared  that the orange snow was caused by a heavy sandstorm in neighboring Kazakhstan - an area used by the Soviet Union to conduct its nuclear tests. and hevily polluted by metallurgy and chemicals factories in Ust-Kamenogorsk. 

A​ more recent event occurred in January 2018 when residents of a town in central Kazakhstan witnessed black snow because of air pollution from the iron and steel industry. 

In 2017,  meanwhile,  the sun and sky over the U.K. turned red as a result of Hurricane Ophelia dragging tropical air and dust from the Sahara.
