Beijing Braces for Heavy Rain with Highland Shelters
Beijing issued multiple weather warnings on Sunday morning as short-duration heavy rainfall was expected to sweep across the capital, testing a new network of 1,052 “highland fortresses” built to protect mountain communities from flash floods.
The Beijing Meteorological Observatory issued a blue rainstorm warning on the morning of August 2, forecasting hourly rainfall exceeding 50mm in districts including Huairou, Miyun, Mentougou, Fangshan, and Haidian, with six-hour rainfall potentially reaching 70mm or more, according to Xinhua News. A yellow thunderstorm warning was issued concurrently, predicting strong short-duration rainfall accompanied by winds of 6-7 levels.
Multiple Concurrent Warnings
The Beijing Water Affairs Bureau and Meteorological Bureau jointly issued a blue mountain flood risk warning and a blue waterlogging risk warning covering August 2 from 12:00 to August 3 at 8:00. Authorities advised residents to avoid mountainous areas, stay away from flood channels, and refrain from driving through waterlogged roads.
The Highland Fortress System
The warnings come as Beijing’s mountain districts prepare to deploy a significant new flood prevention asset: a network of 1,052 highland fortresses completed since the second half of 2025. These emergency shelters, built on elevated terrain, are designed to protect mountain village residents during flash floods when roads, power, and communications may all be simultaneously disrupted.
According to CCTV News, the fortresses repurpose existing buildings such as Party-mass service centers, village committee offices, and cultural centers, alongside newly constructed modular emergency shelter units. Each fortress is equipped with standardized emergency power supply, satellite communications, and emergency broadcasting facilities, with some districts requiring supplies sufficient for 72 hours of independent operation.
“During emergencies, villagers can be promptly transferred here,” said Wang Yongshan, Party Branch Secretary of Shuiquanzi Village in Yanqing District. “We have emergency power—diesel generators—plus satellite phones, water, food, life jackets, gongs, and whistles. All personnel can be transferred to shelters within 24 hours.”
Learning from Past Disasters
The fortress program was catalyzed by the devastating “23-7” extreme rainstorm of July 2023, which caused catastrophic damage in Mentougou and Fangshan districts. The July 26, 2025 event in Yanqing’s Guojiawan Village further exposed weaknesses in temporary evacuation shelters, including inadequate space and a lack of communication and supply capabilities.
Xu Xuelin, a propaganda committee member of Sihai Town in Yanqing District, recalled: “The temporarily requisitioned venues’ space, structure, and personnel accommodation needs didn’t match. They lacked communication, emergency command, and living supplies. The current highland fortresses are scientifically evaluated as safe.”
Digital Monitoring and Community Preparedness
Mentougou District has deployed the Jingxi Sentinel monitoring, warning, and command dispatch platform to track evacuation progress in real-time. Each village maintains a transfer ledger, and residents’ QR codes are scanned upon arrival at fortresses to confirm their safe transfer, as reported by CNR.
Beijing has completed four-level risk zone classification for 1,223 mountain flood disaster risk villages and mapped the threat ranges of 9,615 geological hazard points, according to Li Yu, Deputy Director of the Beijing Emergency Management Bureau. Each village has a detailed transfer plan integrated into the city’s flood situation analysis and command dispatch system.
A Critical Test Ahead
The fortresses face their most significant test during the qixiabashang period—the critical flood prevention window from late July to mid-August. Beijing’s 2026 flood season is expected to see 10-40% more precipitation than average, with forecasts of 510-590mm against a normal of 432.5mm, according to Beijing Daily.
During Typhoon Bavi’s approach in early July, the system saw its first major deployment. In Nanzinfang Village, Tanzhesi Town, 42 households comprising 122 people were transferred to highland fortresses, while Pinggu’s Taoyuan Village housed 35 residents for four nights.
“Highland fortresses are an effective supplement to centralized shelters,” said Zhang Hua, Deputy Mayor of Tanzhesi Town. “When a warning is issued but no danger has occurred, there’s enough time to transfer villagers to larger centralized shelters. But if sudden extreme weather occurs, villagers need to be moved to relatively safe places in a very short time.”
Looking Forward
As the capital enters its most dangerous flood period, the highland fortress network represents a significant evolution in Beijing’s disaster preparedness—from temporary, ad-hoc shelters to a comprehensive system ensuring that even in the worst-case scenario of complete isolation, mountain residents have access to water, power, communication, and supplies within 24 hours. The coming weeks will determine how effectively this new infrastructure holds up under the pressure of extreme weather.
