Chongqing Flooding: 1 Dead, 17 Missing After Historic Rains

A historically rare extreme rainstorm struck Yongchuan District in Chongqing, China, overnight on May 23-24, leaving one person confirmed dead and 17 others missing. The torrential rainfall — reaching 296.6 mm in just two hours between 2:00 AM and 4:00 AM in the Chashan Zhuhai Street area — triggered devastating flash floods and mudslides that swept through communities, according to Xinhua News.

Unprecedented Rainfall

The rainfall intensity was extraordinary by any measure. The Guankouwan station recorded 296.7 mm, the highest in the region, while Hanjiagou Village saw 256.9 mm. The maximum hourly rainfall reached 103.6 mm. CCTV News reported that the Yongchuan Meteorological Station had upgraded to an Orange Rainstorm Warning at 1:40 AM on May 24, alerting 24 townships across the district.

A Tencent News report noted that beyond Yongchuan, 55 rainfall stations across nine districts — including Liangjiang New Area, Beibei, Banan, Hechuan, Dazu, Rongchang, Changshou, and Fuling — recorded torrential rain levels, while 134 stations across 15 districts recorded heavy rain.

Emergency Response Activated

Chongqing authorities moved swiftly in response. At 7:00 AM on May 24, the municipality activated a Level III geological disaster emergency response for Yongchuan District and a Level IV response for seven neighboring districts: Dazu, Rongchang, Hechuan, Tongliang, Bishan, Beibei, and Banan. A Level III flood control emergency response was also activated for Yongchuan and four other districts.

At the national level, the Ministry of Water Resources activated a Level IV flood defense emergency response for Anhui, Henan, Chongqing, and Shaanxi provinces at 9:00 AM on May 24, while maintaining existing Level IV responses for Jiangxi, Hubei, and Hunan provinces.

Pre-Disaster Warnings

The Chongqing Emergency Management Bureau had issued a weather warning on May 22, predicting sustained rainfall from May 23 to 27 with cumulative precipitation of 80 to 180 mm in central and eastern areas. The bureau’s warning specifically cautioned that nighttime rainfall would be significant, accompanied by thunderstorms, short-duration heavy precipitation, and gusty winds. However, the actual intensity — with some areas receiving nearly 300 mm in a single two-hour window — far exceeded forecasts.

Broader Regional Crisis

The Chongqing disaster is part of a much larger weather system that has been battering central and southern China since mid-May. At least seven provinces have been affected, with the cumulative death toll reaching at least 22 as of May 21. Hunan Province has been particularly hard-hit: in Shimen County, Jinjiahe Village was nearly completely destroyed by flash floods and mudslides, with 7 dead and 14 missing as of May 22.

The Xinhua News Agency reported that the Hunan Meteorological Bureau raised its rainstorm emergency response from Level III to Level II on May 23, noting that the current rainfall system overlaps significantly with areas already devastated in Changde, Zhangjiajie, Huaihua, and Yiyang — dramatically increasing the risk of further disasters.

Meteorological Factors

The extreme weather is being driven by a southern branch trough combined with warm, moist air from the periphery of the subtropical high-pressure system. Since May 16, northern and central Hunan has experienced heavy cumulative rainfall with notable nighttime intensity. The already saturated soil has made the region highly vulnerable to landslides, mudslides, and flash floods.

What to Watch For

With the Chongqing Emergency Management Bureau forecasting continued rainfall through May 27, the risk of further flooding, landslides, and additional casualties remains critically high. Search and rescue operations in Yongchuan are ongoing but are being hampered by damaged roads, destroyed bridges, and disrupted communication networks. The 17 missing persons remain the focus of intensive efforts, though the likelihood of finding survivors diminishes with each passing hour.

This extreme weather event — described as the strongest storm to hit China so far in 2026 — underscores the increasing frequency of intense rainfall events consistent with climate change patterns affecting the region. The ability of early warning systems and emergency response infrastructure to keep pace with unprecedented weather extremes will remain a pressing question in the days ahead.
