Weeks of heavy rainfall have once again put large parts of southern China on alert, as authorities brace for a complex flood season in 2026. Provinces, including Guangdong and Guizhou, have already activated emergency flood responses following intense downpours, while meteorological agencies warned that saturated soil and overlapping rain belts are increasing the risks of flash floods, landslides and urban waterlogging.

China's Ministry of Water Resources warned in April that this year could bring both severe flooding and drought in different parts of the country. According to the ministry, northern regions may face unusually strong floods, while typhoons are expected to move further inland during the summer flood season.

In response to growing climate-related risks, China has accelerated the use of advanced technology in flood prevention and disaster response. According to the Ministry of Water Resources and the China Meteorological Administration, authorities are increasingly relying on integrated monitoring systems that combine satellite data, weather radar, hydrological modeling and artificial intelligence (AI) to improve early-warning accuracy.

The Ministry of Emergency Management said in April that local governments were instructed to expand warning coverage and ensure alerts can reach villages, households and construction sites more quickly.

Technology is also reshaping local disaster preparedness. Local flood-control authorities said reservoirs, river embankments and drainage systems are now monitored through digital platforms capable of tracking rainfall, water levels and infrastructure conditions in real time. Officials added that inspections and flood-control measures have been strengthened for reservoirs, urban drainage networks and other low-lying areas vulnerable to flooding.

AI is becoming another important tool. In January, scientists from the Hong Kong University of Science and Technology launched a new AI weather forecasting model capable of predicting heavy rainfall and thunderstorms up to four hours in advance. According to researchers, the system uses satellite data from China's Fengyun-4 meteorological satellite and improved forecast accuracy by more than 15% during testing.

As extreme weather becomes more frequent around the world, China is increasingly turning to AI, satellite technology and real-time monitoring systems to improve disaster prevention and reduce flood risks. Officials say the goal is not only to respond faster, but also to better protect lives and infrastructure before disasters strike.
