How to avoid heavy rainfall?
How much rain has it been in the south lately?
From 8 o'clock on April 19 to 7 o'clock on the 22nd, the rainfall in the south mainly occurred in the northern and central eastern parts of Guangxi, Guangdong, southwestern Fujian, southern Hunan, southern Jiangxi and other places, and the cumulative precipitation in many places in northern Guangdong reached 200 to 300 mm. Among them, the daily precipitation in Shenzhen, Conghua, Fogang, Shaoguan, Lianzhou and other places in Guangdong exceeded the local single-day precipitation extreme value in April.
Not only in the past two days, but since the end of March, many places in the south have suffered extreme precipitation, especially in southern China, with a cumulative precipitation of more than 750 mm in Shaoguan, Guangdong. According to the statistics of the National Meteorological Information Center, from 20 o'clock on March 31 to 20 o'clock on April 21, a total of 231 stations broke the April record in terms of daily precipitation at 231 stations in the mainland, 94 stations broke the April record, and 2 stations even broke the local historical record.
What are the effects of heavy rainfall on the region?
Affected by the continuous heavy rainfall, many rivers such as the Hejiang River and the Beijiang River in Guangdong, and the Guijiang River and its tributaries in Guangxi have experienced super-alert floods. According to the Ministry of Water Resources, at 20:45 on April 20, the flow rate of the Shijiao Hydrological Station on the main stream of the Beijiang River in Guangdong rose to 12,000 cubic meters per second, according to the Ministry of Water Resources's "Regulations on the Numbering of Major River Floods in the Country", numbered as "Beijiang Flood No. 2 in 2024". As of 16:00 on April 21, a total of 24 rivers and 38 hydrological stations in Guangdong exceeded the alert water level. Heavy rainfall in South China will continue in the near future, and catastrophic flooding will occur in the Beijiang River in the Pearl River Basin.
The continuous heavy rainfall has also adversely affected production, life, transportation and travel. On the 20th, a landslide occurred in Zhaoping, Guangxi, and Hezhou, Wuzhou and other places suffered different degrees of waterlogging. On the 21st, many places in Guangdong issued notices of class suspension and scenic spot closure, and there was a small delay at Guangzhou Baiyun Airport.
How long will it rain in the south?
Which areas need to be particularly vigilant for disasters?
The Central Meteorological Observatory predicts that in late April, most parts of the south will still have a lot of rainfall, and the southern part of the Yangtze River and the central and northern parts of South China will experience continuous heavy rainfall, and the cumulative precipitation will be more than twice that of the same period in normal years.
According to China Weather Network, during the day on the 24th, the rainfall in the above areas will weaken significantly, but at night, with the enhancement of water vapor transport, a new round of precipitation will unfold. From the 24th to the 26th, moderate to heavy rain will occur in Jiangnan, South China and Guizhou, with localized heavy rain or heavy rain, accompanied by strong convective weather. Wang Weiyue introduced that the 25th will be the strongest rainfall period in this round of process, and the central and northern parts of Guangdong may encounter heavy rainfall.
The rain in the south will weaken briefly around the 27th, but from the 28th to the 30th, as the southern branch trough moves eastward, the water vapor conditions will improve again, and moderate to heavy rain will occur in Jianghan, western Jianghuai, Jiangnan, South China and Guizhou, accompanied by strong convective weather.
General Office of National Defense, Ministry of Emergency Management:
Prepare for a new round of heavy rainfall
On April 22, the General Office of National Defense and the Ministry of Emergency Management continued to organize the China Meteorological Administration, the Ministry of Water Resources, the Ministry of Natural Resources and other departments to carry out joint consultations, and video dispatch Guangdong, Guangxi, Zhejiang, Fujian, Jiangxi and other key provinces to study and judge the current flood development trend and study and deploy flood prevention and disaster relief work. Wang Daoxi, Vice Minister of Emergency Management and Vice Minister of Water Resources, presided over the meeting.
The meeting pointed out that at present, the current round of rainfall in South China and Jiangnan tends to weaken, but there is still more precipitation in the south in the later period, and the local rainfall intensity is larger, affected by the superposition effect of heavy rain and floods, the risks of river floods, mountain floods, geological disasters, and urban waterlogging are prominent, and the situation of flood control and flood control is still grim.
The meeting demanded that the working group of the General Office of National Defense should strengthen supervision and guidance in key areas. Key areas should attach great importance to the safety of flood control projects, make good use of high-tech equipment for patrolling embankments and checking dangers, and strengthen the inspection and defense of embankments such as the Beijiang embankment; it is necessary to put rescue forces in advance for important parts and weak links, prepare sufficient emergency and disaster relief materials, quickly organize rescue and rescue, make every effort to ensure the rescue and rescue life channel in Jiangwan Town, Wujiang District, Shaoguan City, and seize the intermittent period to make preparations for the next round of heavy rainfall prevention and response; The plan for the safe transfer of people in high-risk areas should resolutely transfer threatened personnel in advance, strengthen the management of the resettlement of transferred personnel, and strictly prevent casualties caused by unauthorized return before the danger is lifted; it is necessary to restore the basic livelihood and normal production and living order of the disaster-stricken masses as soon as possible, remove urban and rural waterlogging as soon as possible, and carry out timely dredging and sanitizing work; in areas where water recedes should seriously carry out investigation and elimination of hidden dangers; strengthen the investigation of old dangerous houses and temporary buildings in flooded areas, and prevent the occurrence of secondary disasters.
