Strange orange snow has fallen in cities in Russia, Bulgaria, Ukraine and Romania.
Footage of the phenomenon has gone viral with people comparing it to Mars
Scientists have blamed the bizarre snow on a combination of sand and pollen
Ski resorts resembled sandy beaches after turning orange while several witnesses said the scenes looked ‘apocalyptic’ and compared it to the surface of Mars.
Experts blamed the weird snow – which in some places even looked brown – on a combination of sand and pollen, reports the Sunday Express.
Scientists from the Sochi Centre of Hydrometeorology and Monitoring of the Black and Azov Seas arrived to test the strange snow yesterday.
A spokesman said it was likely the result of winds blowing sand from the Sahara desert, which then fell as rain.
They predict the snow will return to normal within days.
Tourists at a ski resort at the 2014 Winter Olympic Games site, Sochi, in Russia, shared pictures of the phenomenon.
One user said: ‘Snowy slopes were transformed into barkhan dunes.’
And another wrote: ‘Martian landscape, Apocalypse Now.’
Pictures of the orange snow were also posted from Bulgaria, Ukraine and Romania.
This is not the first snow related phenomenon.
In 2007, orange-tinted snow fell in Siberia. Some experts blamed it on a nearby sandstorm.
