China floods: Gansu death toll rises to 25 as alerts persist

China has raised the death toll from flash floods in Gansu province to 25 as heavy rain continues to sweep across large parts of the country and authorities brace for the possible arrival of Typhoon Dolphin. The floods, which hit Weiyuan county last Sunday, also injured 23 people, the state news agency Xinhua reported on Sunday.

The updated figures mark a sharp increase from the previous toll of 10 and underline the severity of the disaster in a region where flash flooding is particularly dangerous. The National Commission for Disaster Prevention, Reduction and Relief has urged the provincial government to investigate the incident and strengthen emergency response measures, according to Xinhua.

Gansu Death Toll Climbs After Flash Floods

Weiyuan county, located in the rugged hills of Gansu, experienced sudden storms that triggered torrents of water through valleys and villages. The initial response was hampered by the speed and intensity of the flooding, which swept away homes and infrastructure before residents could reach higher ground. Search and rescue operations are continuing, and local officials are working to account for all missing persons, though no further details have been released.

The rise in casualties highlights the challenges of predicting and responding to flash floods in mountainous terrain. Unlike riverine flooding, which develops over days, flash floods can occur within hours of intense rainfall, leaving little time for evacuation. The National Commission's request for an investigation suggests that there may be lessons to be learned about early warning systems and community preparedness.

National Response Escalates Across Regions

As Gansu reels from the disaster, other provinces are also on edge. The Ministry of Water Resources on Saturday activated a level 4 emergency flood control response for Heilongjiang province in the northeast, the lowest level in China's four-tier warning system. Similar alerts are in effect across Gansu, Shaanxi, Sichuan, Henan and Hubei, covering a vast swath of the country from the northwest to the central plains.

Heilongjiang has been particularly hard hit, with 19 rivers experiencing flooding. Some water levels have surged up to 1.3 metres above warning thresholds, putting pressure on dikes and reservoirs. The level 4 response calls for increased monitoring, regular reporting and the pre-positioning of rescue equipment, but it also signals that the situation is being watched closely for possible escalation.

The activation of alerts across multiple provinces reflects the widespread nature of the current weather system. Days of persistent rain have left the ground saturated, so any additional precipitation is likely to run off directly into rivers and streams, raising the risk of further flooding and landslides.

Typhoon Dolphin Looms as Rain Persists

Meteorologists are now tracking Typhoon Dolphin, which could bring additional heavy rainfall to parts of China in the coming days. The storm's exact path remains uncertain, but its potential arrival adds a new layer of complexity to the flood response. Typhoons often carry vast amounts of moisture, and when they encounter existing weather fronts, they can produce extreme rainfall that overwhelms drainage systems and leads to rapid river rises.

In the meantime, the authorities remain on high alert across the affected regions. Emergency teams are conducting patrols of riverbanks, checking the integrity of dams and preparing evacuation shelters. The public has been advised to stay alert and follow guidance from local officials.

The combination of ongoing rain, swollen rivers and a possible typhoon presents a stern test for China's flood control infrastructure. As climate change intensifies the water cycle, extreme precipitation events are becoming more frequent and severe. The lessons from Gansu, where a sudden flash flood caused a significant loss of life, will be crucial in shaping future disaster preparedness policies.

With the flood season far from over, the focus now turns to protecting vulnerable communities and ensuring that emergency responders have the resources they need. The coming weeks will reveal whether the country's upgraded alert systems and response mechanisms are sufficient to handle the cascading impacts of back-to-back natural disasters.
