The Central Meteorological Observatory continued to issue an orange warning for heavy rain at 06:00 on June 28:
It is expected that from 08:00 on June 28 to 08:00 on the 29th, there will be heavy to heavy rain in parts of Jiangsu, Anhui, southern Henan, central, eastern and southern Hubei, northern Zhejiang, northern Jiangxi, northern Hunan, southeastern Chongqing, northern Guizhou, southern Sichuan, northeast Yunnan, and southeastern Tibet, among them, there are heavy rainstorms in parts of southern Henan, central Anhui, central Jiangsu, central, eastern and southern Hubei, northern Hunan, southeastern Chongqing, northeast Guizhou, southeastern Tibet and other places. Heavy rain (250~270 mm) in central Hubei and other places. Some of the above areas are accompanied by short-term heavy precipitation (the maximum hourly rainfall is 30~60 mm, and can exceed 80 mm locally), and there are strong convective weather such as thunderstorms and strong winds locally.
Many rivers have floods above the warning level The flood situation in the south is still severe
The Ministry of Water Resources issued a flood notice on the 27th, and at 15:10 on the same day, the No. 3 flood of 2024 occurred in the Xijiang River in the Pearl River Basin. This is the 10th numbered flood in the Pearl River basin since the beginning of the flood season this year, and the most since the statistics of numbered floods in the Pearl River basin in 1998.
At the same time, affected by continuous heavy rainfall, over-alert floods occurred at many stations in the Poyang Lake and Dongting Lake water systems in the Yangtze River basin, and the "Xiangjiang River Flood No. 3 in 2024" was formed on the 26th, and the "Zishui Flood No. 2 in 2024" was formed on the 27th, and the water level of the main stream in the middle and lower reaches of the Yangtze River continued to rise.
Statistics from the Ministry of Water Resources show that from 8 o'clock on the 26th to 8 o'clock on the 27th, 22 rivers in Jiangxi, Hunan, Guangxi, Zhejiang and other places experienced floods above the alarm, among which the Jinjiang River, a tributary of the Ganjiang River, had the largest flood since the measured data were available.
According to the hydrometeorological forecast of the Yangtze River Commission, there will be a heavy precipitation process in the Yangtze River basin from June 28 to July 2, and the main rain area is located in the western part of the Dongting Lake system and near the main stream of the middle and lower reaches of the Yangtze River.
In the face of continuous rain and flood conditions, water conservancy departments have actively carried out flood prevention, strengthened monitoring, forecasting and early warning, strengthened the scheduling of water conservancy projects, and done a good job in the safety of reservoirs and the prevention of floods in small and medium-sized rivers and mountain floods.
At present, the Ministry of Water Resources maintains a flood prevention level IV emergency response for nine provinces: Zhejiang, Anhui, Jiangxi, Hubei, Hunan, Guangxi, Chongqing, Guizhou, and Yunnan.
The water level of Poyang Lake, the largest freshwater lake in the mainland, is beyond alert
Affected by continuous heavy rainfall and upstream water, at about 7 o'clock on June 27, the water level of Xingzi Station, a landmark hydrological station of Poyang Lake, reached 19.03 meters, exceeding the warning water level of 19 meters, and the flood control pressure in the lake area increased.
Poyang Lake is an important "reservoir" of the Yangtze River, which receives water from the five major rivers of Jiangxi - Ganjiang River, Fuhe River, Xinjiang River, Rao River and Xiuhe River, which is transferred and stored by the lake mouth into the Yangtze River.
Since June 22, the northern Jiangxi region has suffered continuous heavy rainfall, and some areas have suffered floods and geological disasters. Wu Xuewen, director of the flood control and drought relief department of the Jiangxi Provincial Emergency Management Department, introduced that the water level of rivers and lakes in northern Jiangxi has risen rapidly due to the overlapping of heavy rainfall areas in the early stage, and the rivers such as Changjiang, Le'an River, Xiuhe and Jinjiang have appeared super-alert floods, and the soil moisture in mountainous areas is saturated, and key areas such as mountain flood geological disasters, small and medium-sized river floods, and urban and rural waterlogging need to be strengthened.
The water level of Dongting Lake has risen by more than 5 meters in 10 days, and the water level in some areas is beyond alert
The reporter learned from the Dongting Lake Water Conservancy Affairs Center in Hunan Province on June 27 that the water level of Dongting Lake, the second largest freshwater lake in the mainland, rose by more than 5 meters in 10 days, and the water surface expanded by about 1,430 square kilometers.
The meteorological and hydrological departments predict that there will still be heavy rainfall in many places in Hunan in the coming week, with local heavy rainfall, and the rainfall in the Dongting Lake area is expected to be about 180 mm, and the water level of Chenglingji Station, the iconic hydrological station of Dongting Lake, will maintain an upward trend.
Dongting Lake has always been a key area for flood control and flood control in Hunan, and is also one of the most important storage lakes in the Yangtze River basin. Recently, the upstream water flow of Dongting Lake has been increasing, and the inflow into the lake has increased from 12,900 cubic meters per second on June 17 to 36,500 cubic meters per second on June 27, of which the Xiangjiang River and Zijiang River have two numbered floods. Affected by this, the water level of Dongting Lake rose significantly faster than the same period in previous years, the water level began to rise on June 17, as of 8 o'clock on June 27, the water level of Chenglingji Station rose to 31.82 meters, and rose by 5.34 meters in 10 days, and the water surface area of Dongting Lake expanded to about 2510 square kilometers.
According to the relevant person in charge of the Dongting Lake Water Conservancy Affairs Center of Hunan Province, in order to cope with the current floods, all parts of the Dongting Lake District have strengthened the investigation and disposal of weak links such as dangerous sections such as sand-based embankments and dangerous buildings through embankments, implemented the preparation of personnel and materials for cross-flood construction projects and were on duty, and paid close attention to the dispatch of inland lakes and inland rivers to transfer and store, open the drainage pumping station, and strive to prevent waterlogging in the embankment.
Six major rivers in Heilongjiang Province have exceeded the alert water level
The reporter learned from the Heilongjiang Provincial Hydrology and Water Resources Center on the 27th that 6 major rivers in the province exceeded the warning water level, and 58 reservoirs exceeded the flood limit.
Nine stations of six major rivers, including the Ussuri River, the Muling River, the Luoli River, the Uken River, the Dani River, and the Hengdao River, exceeded the warning water level by 0.20 to 1.64 meters, of which 4 stations exceeded the guaranteed water level by 0.01 to 0.59 meters; 58 reservoirs in the province exceeded the flood limit by 0.03 to 4.03 meters, including 4 large reservoirs, 11 medium-sized reservoirs, and 43 small reservoirs.
Compared with the same period of the previous year, the water level of 8 rivers, including Hulan River, Ant River, Mudanjiang River, Muling River, Luoli River, Suifen River, Tangwang River and Wuken River, was 0.11 to 2.68 meters higher.
According to reports, affected by precipitation, the water level of the Yanshou section of the Ant River continued to rise, and the water level of the Yanshou Station was 97.72 meters at 11 o'clock on June 27. According to the "Heilongjiang Provincial Water Warning Release Management Measures (Trial)", the Heilongjiang Provincial Hydrology and Water Resources Center issued a yellow warning for flooding in the Yanshou section of the Ant River at 11 o'clock on June 27.
