China Braces for Record Rainfall as Four Alerts Issued
Central and eastern China entered the peak period of a severe rainfall event on May 24, 2026, with the National Meteorological Center issuing four simultaneous weather alerts for heavy rain, flash floods, geological disasters, and severe convective weather. Local precipitation in Hubei, Anhui, and Henan provinces is expected to potentially break historical May records, with cumulative rainfall reaching 200 to 400 millimeters in some areas, according to Xinhua News Agency.
Government Response
The Ministry of Water Resources activated a Level IV flood defense emergency response for Anhui, Henan, Chongqing, and Shaanxi provinces on the morning of May 24, requiring local water departments and river basin management agencies to closely monitor rainfall and flood development, as reported by CCTV News. Existing Level IV responses remain active for Jiangxi, Hubei, and Hunan, bringing the total number of provinces under flood emergency protocols to seven.
Rainfall Intensity and Affected Areas
The current storm system, expected to last through May 27, is impacting a broad swath of central and eastern China. Heavy to torrential rain is forecast across Chongqing, Hunan, Hubei, Henan, Jiangxi, Anhui, Jiangsu, and Zhejiang, with the heaviest precipitation concentrated in Hubei, Anhui, and Henan. Individual weather stations in these provinces could see over 350 mm of rainfall, potentially breaking May historical records.
The main rain belt has shifted significantly northward compared to typical May patterns, bringing the Jianghuai, Huang-Huai, and Jianghan regions into the center of the storm. According to the 21st Century Business Herald, citing the China Weather Network, parts of Jiangsu, Anhui, Henan, and Hubei are expected to experience heavy rain or torrential rain through the weekend.
Broader Context: A Multi-Week Crisis
This is the third major rainfall event to strike China since mid-May. The first wave, described as “the largest-scale rainfall of the year so far,” triggered a Level III emergency response from the China Meteorological Administration and caused significant loss of life. According to The New York Times, heavy rain and flash floods across southern and central China have killed at least 22 people and forced tens of thousands from their homes since mid-May.
The casualties from earlier waves include five deaths and 11 missing in Hunan, 10 deaths in Guangxi after a vehicle was swept into a river, four deaths and five missing in Guizhou, and three deaths and four missing in Hubei’s Xuan’en County. Over 31,000 people have been evacuated in Hunan alone.
Agricultural Risks
The timing of the rainfall poses a significant threat to agriculture. The Huang-Huai region, China’s major winter wheat production area, is currently in the grain-filling stage, making crops particularly vulnerable to heavy rainfall and strong winds that can cause lodging. As reported by Jiemian News, the农业农村部 (Ministry of Agriculture and Rural Affairs) and China Meteorological Administration jointly issued a farmland waterlogging and winter wheat lodging risk warning on May 15, covering Shanxi, Hebei, Henan, Shandong, Hubei, Anhui, and Jiangsu.
Meteorological Explanation
According to China Weather Network analyst Shen Yuyang, the unusual intensity and northward shift of the rain belt is driven by a rare atmospheric configuration. A high-altitude trough carrying cold air is moving eastward and southward, while a blocking high-pressure system over the eastern sea area joins with the subtropical high to channel moisture from the Pacific Ocean, the East China Sea, the South China Sea, and the Bay of Bengal simultaneously northward into central and eastern China. The slow movement of the blocking high causes cold and warm air masses to converge for extended periods, resulting in prolonged rainfall with large cumulative amounts.
Heatwave in the South
While central and eastern China face torrential rain, areas south of the Yangtze River are experiencing rising temperatures. Fujian and Guangdong are facing heatwave conditions with temperatures expected to reach up to 37°C on May 25-26. The city of Fuzhou may see its first heatwave of the year, with three consecutive days of temperatures reaching 37°C.
What to Watch
Authorities warn that the cumulative effect of multiple rainfall events hitting already saturated ground increases the risk of landslides, flash floods, and infrastructure damage. The rainfall is expected to taper off by May 27, after which cold air is forecast to move south, alleviating both the humid conditions in the north and the heatwave in the south. However, questions remain about the full extent of damage to the winter wheat harvest and whether additional emergency response levels will be activated as the situation develops.
