Dual Flood Emergencies on August 13, 2026
On August 13, 2026, extreme rainfall struck eastern Japan and central China, prompting the highest-level weather alerts in both nations. In Japan’s Chiba Prefecture, the Japan Meteorological Agency (JMA) issued a Level Five Emergency Warning—the top tier of its five-level system—covering 14 cities. In China’s Henan province, a levee breach along the Beiru River in Jiaxian County, Pingdingshan City, forced large-scale evacuations after the structure collapsed under the deluge.
Evacuations and Damage in Henan Province
State-run Xinhua News reported that more than 2,000 residents were relocated after the 40-meter-wide breach allowed floodwaters to spread. Authorities also moved over 4,500 people from ten villages in Luohe City as river levels rose. Luohe recorded an average rainfall of 270.1 mm (10.6 in) between Monday afternoon and Wednesday afternoon, with a peak of 434.2 mm (17 in). The National Meteorological Center renewed a yellow alert for heavy rain, warning of continued downpours across Henan and neighboring Hubei province. No casualties were reported in the Chinese affected areas as of the morning of August 13.
Chiba Prefecture’s Level Five Warning and Immediate Impacts
The JMA’s Level Five warning signaled that life-threatening conditions were already occurring. The Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications confirmed one fatality in Ichikawa City, as reported by Kyodo News. More than 100,000 households—primarily in Chiba but also in Ibaraki and Saitama—were urged to evacuate. Public broadcaster NHK showed cars submerged in Kashiwa, and an AFP journalist observed hundreds stranded at Chiba Station after train services were suspended.
Official Responses and Ongoing Relief Efforts
Japanese authorities instructed residents to move to higher floors or designated shelters and deployed emergency crews to close the Chinese levee breach. Both nations activated their highest-level flood-control emergency responses, coordinating rescue operations and monitoring river levels throughout the weekend.
Outlook and Potential Consequences
While water levels were receding in Henan by Thursday morning, officials warned that additional heavy rain could exacerbate flooding. In Japan, the Level Five warning remains in effect until conditions improve, with continued advisories for residents in the 14-city warning zone. The simultaneous crises underscore the region’s vulnerability to extreme precipitation events and the importance of rapid emergency mobilization.
