China News Network Beijing, June 3, starting on the 2nd, most of the southern region has entered a week-long "rainy day long standby", ushered in the longest time since the beginning of this year, the widest range, the largest rainfall. For many southern provinces that have entered the main flood season, this rainfall process is undoubtedly a test. In the past few days, from the national level to the provincial level, weather warning and emergency response have been intensively launched, and flood prevention and flood preparations have been deployed.

Heavy rain in the south keeps short-term heavy precipitation

  Recently, high-temperature rainfall in many places in the south has hit both, and it has not completely eased from the "under water" mode, and most of the south will usher in a strong rainstorm.

  The Central Meteorological Observatory predicts that from 20:00 on June 2 to 20:00 on 3 June, southeastern Hubei, northeastern Hunan, central and northern Jiangxi, southern Anhui, southern Jiangsu, Shanghai, central and northern Zhejiang, northwest Guangxi, northern Guangdong, and coastal areas of southern China There are heavy rains in some areas.

  Among them, there are heavy rains (100-150 mm) in parts of southern Anhui, northeastern Jiangxi, and western Zhejiang. Some of the above-mentioned areas are accompanied by short-term heavy precipitation (maximum hourly rainfall of 30 to 50 mm, and the local area can exceed 60 mm), and there are strong convective weather such as thunderstorms and strong winds. To this end, the Central Meteorological Observatory continued to issue a rainstorm blue warning at 18:00 on June 2.

  In terms of locality, Guangdong is still “screen-washed” by rainwater from the 3rd to the 4th. There are moderate to heavy rains in Qingyuan, Shaoguan, and Zhaoqing, heavy rains in some areas, and moderate (thunder) rains in western Guangdong provinces. Local heavy to heavy rains, thunderstorms It is accompanied by short-term strong winds of around 8; there are scattered (thunder) showers in the remaining cities and counties.

  From the night of the 2nd to the 9th, there will be three consecutive rounds of heavy rainfall invading Guangxi, and the areas where the heavy rainfall falls will overlap with the previous process, resulting in a high risk of disaster. From the night of the 2nd to the day of the 3rd, there are heavy convective weather such as heavy rain to heavy rain in Liuzhou, Guilin and other cities, local heavy rain to extra heavy rain, short-term thunderstorm and strong wind.

The three early warnings of meteorology, torrents and geology are continuously issued. Anhui Zhejiang has a high natural disaster risk

  Long rain periods and frequent short-term heavy precipitation increase the possibility of floods, geological disasters, urban and rural waterlogging and other disasters, but also have an adverse impact on agricultural production. The China Meteorological Administration has launched a major meteorological disaster (storm) level IV emergency response on the 2nd.

  At the same time, the Ministry of Water Resources and the China Meteorological Administration jointly issued a meteorological warning for mountain flood disasters at 18:00 on June 2. Mountain flood disasters may occur in parts of central and western Zhejiang, southern Anhui, northeastern and northwestern Jiangxi, and northwestern Guangxi.

  The Ministry of Natural Resources and the China Meteorological Administration also jointly issued a geological hazard meteorological risk early warning on June 2 at 18:00. It is expected that from 20 June 2 to 20 June 3, northwestern Guangxi, northeastern Hunan, northwestern Jiangxi and northeast The meteorological risk of geological disasters in the Ministry of Education, southern Anhui and western Zhejiang is relatively high (yellow warning).

  According to the website of the Ministry of Water Resources, affected by the current round of heavy precipitation, it is expected that the Liujiang and Guijiang rivers in Guangxi, the upper reaches of Beijiang in Guangdong, Xiangjiang and Zishui in Hunan, Ganjiang and Changjiang in Jiangxi, the upper reaches of Qiantang in Zhejiang, and the upper reaches of Minjiang in Fujian There is a significant flooding process, and some super-alarm floods may occur in some small and medium-sized rivers in the rainstorm area; considering the maintenance of later rainfall, the super-alarm floods may occur on the main stream of the above rivers from June 4-7.

The strongest rainfall process since this year: large range, long time, heavy rainfall

  "In the coming week, the southern rainfall has a large impact range, long duration, large accumulated rainfall, and overlapping areas of heavy rainfall in some areas. This is a strong rainfall process since the flood season this year." Chen Tao, chief forecaster of the Central Meteorological Observatory said.

  He explained the reason for this round of heavy rainfall, because after the onset of the monsoon, the water vapor transport to Jiangnan and South China is relatively strong, and the recent weather system is relatively stable, and the main rain belt is steadily maintained from Jiangnan to western and northern South China Around.

  In terms of precipitation time, the rainfall process will last from June 2 to 8, which is about a week.

  Rainfall mainly affects the area south of the Yangtze River, especially in northern Hunan, central and northern Jiangxi, western Zhejiang, southern Guizhou, and northwest Guangxi, where the rainfall time is longer and the accumulated rainfall is larger.

  For example, from the 5th to the 8th, the cumulative rainfall in parts of southeast Guizhou, northwest Guangxi, central Hunan, central and northern Jiangxi, western Zhejiang, and northern Fujian may reach 100 to 200 mm.

  Chen Tao said that the rainfall process took a long time, and landslides, debris flows, flash floods and other disasters may occur in areas with heavy rainfall, and urban waterlogging may occur in urban areas. Be prepared to pay attention to weather forecast warning information and the adverse impact of heavy rainfall on traffic travel at any time.

In order to improve the project's ability to combat floods, rescues, and disasters, and ensure safe production, a central enterprise used fire trucks to simulate sudden rainstorms to carry out emergency drills. Tang Jizheng

Flood prevention situation is not optimistic, deploying heavy rainfall defense work

  The rain situation is not very optimistic, and various departments around the country have made arrangements to deal with this round of precipitation.

  On June 1, the Ministry of Water Resources discussed the deployment of heavy rainfall defense work in Jiangnan, South China, Southwest China and other places to analyze and judge the rain and water conditions and the defense situation. The consultation held that the flood control situation is not optimistic, and we must focus on the safety of reservoirs and prevent floods and mountain floods, and do a good job of all defenses in a targeted manner.

  At the same time, the Ministry of Water Resources also requested that Zhejiang, Anhui, Fujian, Jiangxi, Hunan, Guangxi and other places should give full play to the role of the mountain flood disaster monitoring and early warning system and the group measurement and group prevention system and the three major operators in the prevention of mountain flood disasters. Early warning information.

  The Taihu Basin Administration of the Ministry of Water Resources organized a training exercise on the Taihu Basin Flood Defense on June 1st. Based on the 1999 Taihu Basin Flood, it designed historical flood review and hydrological forecasting, historical flood simulation analysis, and flood response to excess. Measures, execution of dispatching instructions, emergency response to engineering faults, hydrological emergency monitoring, media question and answer, and other scenarios, tested the ability of the Taihu Lake Bureau to respond to the “black swan” incident of excessive floods in the basin.

  The special deployment requirements of the Hunan Provincial Department of Water Resources, earnestly do a good job in the current flood control work, focus on achieving excessive floods without chaos, floods within the standard without accidents, reservoir failures, and mountain flood disasters without mass deaths and injuries; and on May 30 The "Notice on Doing a Good Job in Flood and Drought Disaster Prevention from June to August" was issued on the day, requesting effective defense against floods exceeding the standard.

  At the same time, water conservancy departments in Guangdong and other places require the implementation of a 24-hour duty system during the flood season, closely monitoring changes in rain conditions, and timely issuing rain warning information to provide support for flood control and drought relief decisions.
