Continuous rain in South China's Nanning, Guangxi Zhuang Autonomous Region, has swollen the local Yong-jiang River. At 2 o'clock Tuesday afternoon,it had passed the "early warning level", meaning authorities need to prepare for possible flooding.
Early warning water level is the first step of flood prevention. It means local government should take precautions against flooding and send professionals to carry out a 24-hour survey. The second step is warning water level.
According to the local government's survey, the level of the Yong-jiang River is rising at a speed of 10 centimeters per hour. Rapid water flow from upper reaches is creating difficult conditions for small boats. Officials say, Typhoon Chanthu last week brought abundant rainfall to Guangxi. This is the main reason for the rapid rise of the Yong-jiang River. They also predict water levels will rise by 1 meter in the next 24 hours.
Wei Guanglong, Head of Hydrological Station, said, Yong-jiang River in the Nanning area has risen above the 69 meters early warning water level.
However this means there are still are another 3 meters before it reaches warning water level. However in some low-lying areas, like Pudian county, the flowing water has risen above the warning level.
Ships on the river are also affected. Local government has sent teams to give all ships security checks. Meanwhile, booklets warning about a possible coming flood are also being delivered to all fishermen.
You'd better keep at least one sailor on the boat, so you can transfer your boat to safer places when there's an emergency.
Local government has also issued an emergency notice to warn all residents to prepare for sudden relocation.
