• Weather tracker: Torrential rain in southern China leads to flooding fears

Contesto

Widespread heavy rain is sweeping over southern China, prompting emergency meetings among top disaster relief and management authorities as fears of severe flooding escalate. By Wednesday, rainfall totals are expected to exceed 100mm across many parts of Guangxi, Guangdong, Fujian, Zhejiang, Jiangxi and Hunan provinces, with some areas forecast to receive as much as 150-200mm. The Office of the State Flood Control and Drought Relief Headquarters and the Ministry of Emergency Management have convened with meteorological and hydrological departments to coordinate reinforced patrols and emergency response measures aimed at mitigating the probable flooding that the intense rainfall is expected to bring. The deluge comes as contrasting extreme weather grips other parts of the hemisphere. Heatwaves across India have pushed temperatures to 45 degrees Celsius, while unseasonably cold weather is affecting parts of central Canada, underscoring a pattern of volatile climate conditions spanning multiple continents. In China, authorities have specifically ordered that reservoirs with known safety concerns must remain empty during the rainfall period and throughout the coming rainy season, a precautionary step reflecting heightened vigilance after previous flood disasters in the region. The affected provinces form a broad arc across southern China, encompassing densely populated urban centers as well as vast agricultural areas. Guangdong, one of China's most economically vital provinces, is particularly vulnerable due to its low-lying terrain and extensive river systems. The 100-200mm rainfall forecast represents a significant volume that could overwhelm drainage infrastructure and trigger flash floods, especially in mountainous areas where runoff is rapid and landslides are a secondary threat. China's flood control apparatus has been on alert since early spring, with the State Flood Control and Drought Relief Headquarters issuing repeated warnings about above-average precipitation forecasts for the year. The current system, which is drawing moisture from the South China Sea, aligns with the climatological peak of the East Asian monsoon season, when southern China typically...
