Because of snowstorm airport was closed in South-Sakhalinsk, informed the head administration of Russian Emergency Ministry over island territory. "Airport is closed for arrivals and departures of airplanes until 12:00 by local time (05:00 by Moscow time)". Airplanes, flying to Sakhalin, are directed to reserve airdromes in Vladivostok and Habarovsk. The day before airport in South-Sakhalinsk was closed because of ice formation at landing ground. "This is an ordinary phenomenon for this season", - consider experts. Since November 29 rains and snowstorms fall with short intervals. Unstable weather is caused by cyclones from the Pacific Ocean, the Japan Sea and the continent.
