Bulgaria's Foreign Ministry has sent a note warning the authorities of Turkey and Greece about the overflowing of major water dams on Bulgarian territory.

Bulgaria's Ministry of Foreign Affairs, in a note this morning, informed Greek and Turkish authorities that the Ivailovgrad water reservoir and the Studen Kladenetz water reservoir will begin to overflow.

The volume of water expected to discharge from the dam is 268 cubic meters per second.

According to Bulgaria's National Institute of Meteorology and Hydrology (NIMH), February 6 2012 will see rain in southern Bulgaria while positive temperatures will cause snow at altitudes of less than 1500 meters to melt.

Rain will turn to snow in the eastern regions and wind will increase, in places exceeding 15 to 20 meters a second.

During the precipitation period, snow across the country will rise by 20 to 50cm, and in the Rhodope region, rainfall will reach – and in places surpass – 50 to 100 liters a square meter.

Over the next few days, minimum temperatures in most areas will be between minus 15 and minus 20 degrees Celsius, in some places even lower.

"The Ministry of Foreign Affairs will give Bulgaria's southern neighbors immediate notice of any change in water status and risk of flooding," Bulgaria's Foreign Ministry says.
