“There will be enough snow, that issue doesn’t disturb us,” said Alexander Frolov, head of the Russian Weather Service (Rosgidromet).
On the contrary, he said, there are concerns that heavy snowfall could seriously disrupt the competition in Sochi.
He warned that weather in that subtropical zone is very volatile and snowstorms there, once started, might last for two or three consecutive days.
Earlier, the Russian Emergency Situations Ministry had issued an avalanche warning in Sochi.
Avalanches in the mountainous area could cause possible blackouts, disruption of communications, housing services and transportation.
