Sochi will have enough snow for Olympics

The snow in the mountains around Sochi is already deep enough to successfully run events at the February Olympics according to organisers.

Sochi will have enough snow for the Winter Olympics in February, Russia's chief weather forecaster vowed on Friday.

Concerns were raised after two test events in Sochi had to be cancelled last February because of a lack of snow or rainy weather at the resort city on the Black Sea.

Organisers, however, worked out a Plan B, which included storing 450,000 cubic metres of last year's snow on the slopes through summer and installing what they described as Europe's biggest snow-making system.

But Roman Vilfand, director of the Russian Meteorological Office, said on Friday the organisers will probably not need the extra snow because data shows that Sochi will have enough natural snow.

The depth in the mountains above Sochi is already 52 centimetres, unusually high for this time of year, Vilfand told the Itar-TASS news agency.

He insisted the snow base will stay even if January is warm and rainy.

"For the snow cover this deep, this isn't a problem," he said.

The 2014 Winter Olympics, which run from February 7-23, will hold indoor events like skating and ice hockey in the coastal city of Sochi while outdoor sports will be held in the mountains dozens of kilometres away from the coast.
