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

Concerns about a snowless Olympics were raised after two test events in Sochi had to be canceled last February because of a lack of snow or rainy weather. Organizers, however, worked out a Plan B, which included installing what they described as Europe’s biggest snow-making system.

But Roman Vilfand, director of the Russian Meteorological Office, said Friday the organizers will probably not need the extra snow because data show that Sochi will have enough natural snow. The snow cover now in the mountains above Sochi is already 20 inches, unusually high for this time of year, Vilfand said.
