Guangdong Raises Flood Alert to Level III as Rains Continue

Guangdong Province escalated its flood emergency response to Level III on June 14 as relentless “Dragon Boat Water” rains triggered widespread flooding, forcing the evacuation of more than 13,000 people and disrupting rail services across the manufacturing heartland of southern China. The Guangdong Provincial Flood Control Headquarters raised the alert level at 19:00 local time, citing dangerously saturated soils, elevated river levels, and forecasts of continued heavy precipitation through at least June 20.

Background: An Extended Monsoon Season

The current crisis is part of the annual “Dragon Boat Water” (龙舟水) season, a meteorological phenomenon unique to southern China that typically runs from May 21 to June 20. During this period, warm, moisture-laden air from the South China Sea collides with lingering continental air masses, producing prolonged and often intense rainfall. In 2026, the season has been classified as an “extended version,” lasting until June 30, driven by rapidly developing El Niño conditions and a periodically strong summer monsoon.

Earlier in the season, on May 20–21, a hydrological station in Yangjiang recorded 1,053.5 mm of rainfall in 24 hours — a record-breaking event that prompted Level II emergency responses in several cities and the evacuation of 5,533 people. The current wave, described by authorities as the “strongest rainfall process” of the 2026 Dragon Boat Water period, has now surpassed those earlier figures.

Key Developments

As of 20:00 on June 14, a cumulative total of 13,283 people had been evacuated across the province, according to 21 Economic Net. Twelve cities — Guangzhou, Huizhou, Meizhou, Shantou, Shanwei, Jiangmen, Heyuan, Qingyuan, Zhuhai, Shaoguan, Jieyang, and Dongguan — activated flood emergency responses, with Shanwei, Meizhou, Jieyang, and Shantou raising their alerts to Level III. Huilai County in Jieyang activated the highest possible Level I response, underscoring the localized severity of the crisis.

Rainfall data from the 24-hour period ending at 20:00 on June 14 showed an average of 33.9 mm across Guangdong, with the Lufeng Overseas Chinese Management District in Shanwei recording the highest cumulative rainfall at 588.7 mm. Red rainstorm warnings were in effect for seven locations, including Boluo, Heyuan, Huidong, Haifeng, Lufeng, Huilai, and Chaoyang.

A waterspout was confirmed at Honghai Bay in Shanwei at approximately 23:02 on June 13 by the Shanwei Meteorological Bureau and the Foshan Tornado Research Center — a rare and dramatic indicator of the intense convective activity sweeping the region.

Transport Disruptions and Emergency Response

The heavy rains have severely impacted rail travel. According to CCTV News, the Beijing-Kowloon Railway’s Yangcun-Huizhou section saw multiple train diversions, cancellations, and rerouting. Services including the K677, D27, Z310, K1312, K92, T102, K824, and T227 were affected, with some trains transferred to high-speed rail alternatives and others forced to turn back at Dongguan East and Huizhou stations.

Authorities have mobilized substantial resources to manage the crisis. The Guangdong Emergency Management Department deployed 123 drainage rescue teams comprising 6,460 personnel and 463 large pumps, alongside approximately 260 engineering rescue teams with over 12,000 personnel and 3,500 pieces of heavy machinery. Aviation assets — including eight helicopters, a large fixed-wing drone, an unmanned helicopter, and 15 medium-sized composite-wing drone platforms — have been positioned for rapid response. Communications equipment, including 2,767 two-way radios, was pre-deployed to 428 high-risk villages.

The Guangdong Provincial Fire Rescue Corps mobilized 553 personnel across Jiangmen, Yangjiang, Zhuhai, Huizhou, and Guangzhou, with an additional 184 personnel stationed in Heyuan, Dongguan, and Jiangmen. A further 600 personnel in Guangzhou and Chaozhou remain on standby.

Analysis: Why This Wave Is Particularly Dangerous

The current flood threat is amplified by several compounding factors. Soils across Guangdong are already highly saturated from weeks of prior rainfall, dramatically increasing runoff and the risk of flash floods and landslides. River base levels remain elevated, and the forecast shows no significant let-up until at least June 20–21.

The approaching Dragon Boat Festival on June 19 adds a layer of public safety concern, as holiday celebrations and dragon boat races typically draw large crowds to waterways. The Guangdong Emergency Management Department has specifically warned residents to exercise caution during outdoor activities and to remain alert to the risks of lightning, flash flooding, and sudden strong winds.

What’s Next

Meteorological forecasts indicate that heavy to torrential rain will continue across most of Guangdong through June 17, with coastal areas potentially facing extreme downpours. Significant rainfall is expected to persist through June 18–20 before gradually weakening around June 21. National authorities had been tracking the escalating risk for over a week, with the National Flood Control Headquarters activating a Level IV emergency response for Fujian, Guangdong, and Yunnan on June 8.

Whether the provincial response will need to be raised further to Level II depends on whether rainfall totals exceed current forecasts. For now, Guangdong remains in a critical watch period, with emergency services fully mobilized and residents urged to stay informed as the Dragon Boat Water season delivers its most punishing test yet.
