Heavy monsoon rains in mid-July 2026 triggered widespread flooding across nine Chinese provinces and municipalities, including Shanghai, Guangdong, and Yunnan. The Ministry of Emergency Management described the situation as severe and complex, prompting large-scale evacuations, nonstop pumping operations, and debris clearance. In Shanghai's Yangpu District, flash floods submerged roads, while landslides in Chongqing left dozens missing. Experts noted that El Niño exacerbated the weather patterns.

On 26 July, a mountain flash flood struck the Shuangshimen camping site in Weiyuan County, Gansu Province. The death toll was later revised to 25 dead and 23 injured, with roughly 174 campers rescued. This disaster coincided with Typhoon Noul’s impact on Guangdong, for which the central government allocated 100 million yuan (≈US$14.7 million) for relief.

By early August, heavy rainfall shifted focus toward northwest China. In Shaanxi province, more than 140,000 people had been evacuated since 30 July, including 25,000 within a single 24-hour period. In Gansu's Longnan City, a Level II flood-control emergency response resulted in over 4,500 evacuations and significant infrastructure damage, including approximately 3,303 km of damaged roads. 

In mid-August, torrential rains in southwestern China caused at least 10 additional deaths. In Sichuan province, fatalities occurred due to a roof collapse from rainwater accumulation and a wall collapse. Authorities proactively evacuated over 21,000 people in regions such as Chengdu and Zigong. Additionally, in Guangxi province, officials investigated a landslide at a construction site that trapped five individuals.
