Southern Russia overwhelmed with purple snow
09 March, 2010, 22:43

The very morning following the widely celebrated Woman's Day - people in Southern Russia could not believe their eyes when they found purple snow piled on city streets.

Scientists confirmed a multi-coloured snowfall – ranging from light purple to brown – had landed in Russia's Stavropol Region.

Having analysed the samples, climatologists ruled that the snow is perfectly safe. However, eating purple snow is still not recommended as scientists say it is full of dust from Africa.

A massive dust cyclone rose to upper atmosphere layers and then mixed with regular snow clouds in Russia's South.

So, as a matter of fact, purple snow was an expeditious shipping of African sand beaches to Stavropol region. If it was not for negative temperatures, its residents could already be having sand-bathes.

A similar incident took place some years ago in Russia's Far East.

hmmm
