Torrential rain lashed parts of Guizhou province in southwest China on Sunday, 7 June, unleashing severe floods and compelling authorities to evacuate nearly 10,000 residents across multiple districts. The disaster prompted China's top meteorological and water-resources bodies to jointly issue a top-level red alert for flash floods — the highest warning level available.

Hardest-Hit Areas

The worst-affected zones included Qianxi City, Zunyi City, and Changshun County, according to reports. In Qianxi, relentless downpours from Saturday through the early hours of Sunday inundated all 30 townships in the city, with five townships recording exceptionally heavy rainfall. Emergency teams worked through the night, evacuating 1,377 residents from 491 households and rescuing more than 50 people who had been trapped.

In Changshun County, a power outage disrupted operations at the Bancong reservoir, leading to overflow. More than 3,000 residents from approximately 1,000 households in downstream villages were safely relocated as a precautionary measure.

Red Alert Issued for Southeastern Guizhou

At 6 pm on Sunday, China's Ministry of Water Resources and the China Meteorological Administration jointly issued a top-level red alert for mountain torrents, warning of a high risk of flash floods across parts of southeastern Guizhou from 8 pm Sunday to 8 pm Monday. In response, authorities in Qiandongnan Miao and Dong Autonomous Prefecture stepped up monitoring across 27 rivers and mobilised thousands of officials and flood-control personnel.

As of Sunday evening, 4,582 residents from 1,322 households in Qiandongnan had already been evacuated, while the relocation of a further 21,754 residents from 7,213 households was reportedly underway.

A Season of Repeated Emergencies

The current crisis is the latest in a series of flood-related emergencies to strike Guizhou in recent weeks. On 26 May, China's flood-control authorities activated a Level-IV emergency response for the province. Prior to that, on 19 May, the national commission for disaster prevention, reduction, and relief also activated a Level-IV disaster relief emergency response for Guizhou following severe flooding and geological disasters, according to the Ministry of Emergency Management. Separately, four people died after sudden, extremely heavy rainfall triggered severe flooding and landslides in Guiding County of the province.

This is at least the third emergency activation for Guizhou within a single month, underscoring the province's acute vulnerability to seasonal monsoon extremes. Guizhou's mountainous terrain and river-dense geography make it particularly susceptible to flash floods and landslides when rainfall intensifies.

What Happens Next

Authorities in Qiandongnan are continuing round-the-clock monitoring operations along the 27 rivers flagged under the red alert. The warning period runs through 8 pm on Monday, and officials have not yet indicated when the alert will be downgraded. Residents in downstream and low-lying areas have been urged to remain vigilant and comply with evacuation directives.
