On July 10, 2026, Typhoon Bavi — the 11th named storm of the season — entered the 24-hour warning zone. The Central Meteorological Observatory reported that its outer spiral rainbands had already begun affecting Taiwan, with coastal Zhejiang experiencing the first gusts and showers. Just two days earlier, Typhoon Maysak, the 10th storm, had caused severe flooding in Guangxi and Hunan — two typhoons striking within the same week, placing China's emergency response system under rare, sustained continuity pressure.
From the emergency rescue at Guigang, Guangxi, to the heavy rain warnings across the Beijing-Tianjin-Hebei region; from drones airlifting stranded residents to columns of military vehicles rushing to the front — this mid-July story is about far more than meteorological forecasts and technical operations. It is a complete picture of a multi-front mobilization by China's emergency response system during a period of compounding extreme weather.
From Maysak to Bavi: Double Pressure in Two Weeks
In early July, Typhoon Maysak triggered a dam breach at the Liulan Reservoir in Hengzhou, Guangxi. A snake farm in Dengwei Village was washed out by the floodwaters — eight or nine hundred snakes swept into the village, and snake-catcher teams had to go door-to-door on a search-and-retrieve mission. Meanwhile, the Guangxi Guigang Education Park — home to around 10,000 faculty and students — became a waterlocked island, completely encircled by floodwaters.
The Guangxi floodwaters had barely receded before Bavi formed over the western Pacific. On the afternoon of July 10, the Central Meteorological Observatory reported that Bavi had entered the 24-hour warning zone: a large, powerful typhoon with a prolonged impact. Areas from the Beijing-Tianjin-Hebei region could expect regional heavy to torrential rain; southeastern Zhejiang and northeastern Fujian faced 500–600 mm of localized rainfall, with some parts of Taiwan possibly exceeding 1,000 mm.
On the same day, July 10, the Ministry of Natural Resources activated geological disaster defense responses at Level III (Fujian–Zhejiang) and Level IV (Beijing–Tianjin–Hebei) simultaneously. This pattern of "sustained rescue in the south + parallel warning in the north" placed a unique demand on a nation's emergency mobilization capacity.
Drones Airlifting People — When the People's Weight Exceeds the Rules
One rescue story from the Guangxi floods drew widespread attention. In Yunbiao Town, two stranded residents — a driver trapped on top of a fuel tanker and an ill villager — could not be reached by boat or by any land route. The rescue team used heavy-lift drones to airlift them to safety.
Under normal operating procedures, drones are strictly prohibited from carrying personnel. This safety boundary was forged through countless accidents. But the on-site commander gave a blunt and powerful reply: "In principle, drones don't carry people. But the people outweigh the principle."
In his analysis, Shen Yi distilled this detail into a core judgment of what genuine public service means in practice. He also highlighted an institutional dimension — DJI Agriculture issued a special announcement offering after-sales support for drones used in the Guangxi rescue, authorizing free repairs at all nationwide service centers. "This meant civilian drone pilots could throw themselves into the rescue effort without worrying about the economic cost of equipment damage."

Columns of Military Vehicles: Saturation Rescue Made Visible
On the streets of Guigang, Guangxi, rows of olive-drab military vehicles stretched end to end, their headlights forming an unbroken chain. According to official data: the People's Liberation Army and the Armed Police Force dispatched over 2,400 personnel, more than 70 boats and inflatables, and over 260 vehicles and engineering machines, while 5,500-plus militia members were mobilized.
Junzhengping, in its commentary on the military convoy, pointed to the signal behind the visual: "What it conveys is not just the scale, but a determination: spare no cost, leave no blind spot."
More than 2,400 active-duty troops + 5,500-plus militia members + over 260 engineering vehicles — operating in a single coordinated response. That set of figures is itself a measure of institutionalized mobilization capacity.
Multiple Fronts on the Same Day
The information flow on July 10 presented a rare density. The Ministry of Natural Resources activated a Level IV geological disaster defense response for Beijing and Hebei; a working group was dispatched to Fujian and Zhejiang to guide Typhoon Bavi defense; People's Daily published a documentary on the "island rescue" at the Guigang Education Park; three roads in Beijing's Fangshan District were placed under traffic control; heavy-rain warnings blanketed the Beijing-Tianjin-Hebei region — with localized rainfall in Taiwan potentially exceeding 1,000 millimeters. On the same day, three parallel fronts demanded a single administrative system manage attention resources on an hourly basis.
This essay overlaps with "Emergency Technology in the Guangxi Floods — Powered Pontoon Bridges, Drones, and Emergency Communications Under Real-World Testing" in subject matter, but takes a different narrative angle. That piece focuses on the field testing of emergency tech equipment during Typhoon Maysak; this essay uses the multi-front mobilization triggered by Bavi's arrival as its narrative mainline.
A Historic Moment: Three Warnings Issued Simultaneously
At 10:00 AM on July 11, the Central Meteorological Observatory simultaneously issued three warnings: a Red Alert for heavy rain (the first of the year), an Orange Alert for typhoon, and a Yellow Alert for severe convective weather. Issuing three warnings at once is rare in the history of meteorological alerts. It meant that on a single day, China faced the superposition of three distinct weather systems — from the East China Sea coast to the North China Plain to the Northeast.
Bavi's gale-force wind radius had expanded to over 500 km. Its long-distance moisture transport, combined with the westerly trough and the Western Pacific subtropical high, created a "moisture corridor" cutting across central and eastern China — from the East China Sea, through the Yangtze River Delta, and straight to Beijing and Tianjin.
Escalating Emergency Response Levels
| Time | Action | Basis |
|---|---|---|
| 11:00 | Zhejiang typhoon response raised to Level I | Provincial flood control assessment |
| 11:00 | National flood control activates Level IV response for Shanghai, Jiangsu, Anhui, Jiangxi, Sichuan | Red Alert for heavy rain + Orange Alert for typhoon |
| Night | Beijing activates Level I flood control emergency response in 8 districts | Red Alert for heavy rain |
Beijing evacuated 38,130 households / 104,042 people and closed 181 tourist attractions. As of 11:00 on July 11, flight tracking data indicated Bavi would affect 56 airports; all inbound and outbound flights at Wenzhou Longwan, Fuzhou Changle, and other airports were cancelled.
Beijing's Red Alert for Heavy Rain and the Legal Boundaries of AI Forecasting
At 3:00 PM on July 11, the Beijing Meteorological Observatory upgraded the heavy rain warning to a zonal Red Alert — nine districts were placed under the heavy rain warning zone. At 4:00 PM, the Beijing Emergency Management Office released a 10-point protection guideline: enterprises and institutions should not require employees to report to work unless necessary; residents should not go outdoors unless necessary; underground commercial venues were ordered closed; construction sites were shut down.
On the same day, People's Daily published an editorial titled "Typhoons Cannot Be Left to Simple AI Predictions," explicitly stating that bloggers using AI weather models to issue typhoon track and rainfall predictions risked violating the Meteorological Law. Article 22 of China's Meteorological Law establishes a "unified public meteorological forecast issuance system" — not designed to restrict the free flow of information, but to ensure the authority of disaster warnings. In an era when AI technology enables anyone to generate meteorologically convincing-looking graphics, this line requires every person with a platform to ask themselves: is what I am putting out "science communication" or "forecasting"?
Second Impact After Landfall: From Zhejiang to Beijing-Tianjin-Hebei
Around midnight on July 11, Bavi first made landfall at Yuhuan City in Taizhou, Zhejiang, then struck a second time in Yueqing, Wenzhou — making it the first super typhoon of 2026 to make landfall twice within 24 hours. Wind speeds at Jiaojiang, Taizhou reached 54.1 m/s (Category 16), breaking the local all-time wind speed record.
Post-disaster emergency response was swift. The National Development and Reform Commission urgently allocated 100 million yuan (approx. US$13.8M) from central budgetary investment to support post-typhoon recovery in Zhejiang. Meanwhile, Bavi did not weaken rapidly after landfall — it traveled northeast along the coast of Anhui to the Yellow Sea, continuing to affect eastern, northern, and northeastern China.
Between July 10 and 12, 111 stations in the Beijing-Tianjin-Hebei region recorded precipitation exceeding historical extremes (40 in Beijing, 46 in Hebei, 25 in Tianjin). Qianxi in Hebei posted 315.3 mm — breaking the single-day precipitation record in local observational history. Across all 509 weather stations in Beijing, 52.2% registered heavy rain levels.
China Weather Network analyst Li Ning explained that Bavi acted as a giant moisture pump, drawing vast quantities of water vapor into the transport channel along the edge of the subtropical high — greatly increasing the moisture supply reaching North and Northeast China from upstream. This, combined with the orographic lift of the Taihang and Yan Mountains and the "train effect" of successive storm cells, produced intense rainfall in the Beijing-Tianjin-Hebei region, far from the typhoon's center.
Secondary Shock: Northeast China's Heavy Rain
Bavi's remnant circulation triggered a precipitation peak in Northeast China on July 13. By 9:00 AM, Shenyang had recorded 181.2 mm of rainfall — classified as very heavy rain. Three consecutive hours of short-duration intense precipitation constituted a "rain train effect." The Shenyang flood control and drought relief headquarters issued a citywide Red Alert for flood control, raising the response to Level I.
Bai Mengchen, writing about the scene as a commentator, offered a personal observation: "Northern China's municipal engineering — urban design as a whole, probably — was never built for this kind of thing. Time to adjust." This individual assessment — that "system design expectations fall short" — paired with the institutional confidence in official announcements, created two layers of on-the-ground record-keeping.
From Rescue to Observation: The Technological Leap of Swarm Drones
On July 26, Typhoon Hongxia made landfall in Huizhou, Guangdong. What set this event apart was that meteorological researchers used a swarm of drones to observe the entire typhoon passage — the first systematic test conducted under China's Meteorological Administration's low-altitude economy unmanned aviation weather assurance field science experiment base.
This test demonstrated the expansion of Chinese drone technology from a "rescue tool" to a "scientific observation platform" — in early July, drones in Guangxi were used to airlift stranded residents (physical rescue); in late July, drones in Shenzhen were used to probe typhoon structure (scientific observation). The same technological base found applications in two entirely different scenarios.
From rescue to observation, from emergency to prevention — Bavi tested response speed; Hongxia tested predictive capability. Together, they complete the full loop of "pre-disaster observation → disaster response → post-disaster recovery" in a system built to handle extreme weather events.
The Cognitive Framework for Extreme Weather as the New Normal
On July 15 — the traditional start of the sanfu "dog days" of summer — Chang'anjie Zhishi (a commentary account affiliated with Beijing Daily) published an in-depth commentary with a core thesis: the old pattern of "drought in the north, floods in the south" has fundamentally shifted. The southern plum-rain season is no longer "fine" or "moldy"; the north is becoming increasingly wet, with the rainy season arriving earlier, lasting longer, and bringing more intense events.
The commentary also offered a measured response to the common call — "we should just build everything to a once-in-a-millennium standard": requiring all infrastructure to meet "once-in-a-millennium" specifications is neither consistent with the probabilistic nature of disaster risk nor economically affordable. The better path runs through the software layer — forecasting and early warnings, drills and exercises, emergency management, and safety protocols.
