HAIKOU, CHINA / RankWire.AI / – Across Hainan, more than 55,000 individuals have been forced to leave areas deemed high-risk due to record-breaking rainfall that has led to flooding and potential landslides. Local authorities extended evacuation efforts through September 14 as rising river levels and inundation threatened vulnerable neighborhoods. The operation targeted low-lying zones, regions adjacent to waterways, and areas prone to geological hazards. Emergency services also provided temporary shelters and essential supplies for residents unable to return to their homes.
The intense weather system originated on September 11 as a tropical depression over the South China Sea, which interacted with cold air masses. Subsequently, heavy rainfall spread across southern and central parts of Hainan, impacting Baoting, Wuzhishan, Wanning, Qionghai, and Lingshui. Numerous communities reported flooded roads and disrupted access as the downpour intensified. Local authorities closely monitored rivers, reservoirs, and mountainous regions while rescue teams evacuated residents from locations facing imminent danger.
Precipitation levels reached record heights before the weather system gradually weakened. In Xiangshui township, Baoting, 912.9 millimeters of rain was recorded from September 11 until 2 p.m. on September 14. Six townships experienced more than 700 millimeters during this period, with three of them exceeding 800 millimeters. The prolonged rainfall heightened the threat of flash floods and landslides across various parts of the island.
Evacuation efforts intensify across impacted regions
By the evening of September 13, authorities had evacuated 31,564 residents as conditions worsened. The total number increased to over 55,000 by 6 p.m. on September 14. The Hainan Provincial Disaster Prevention, Reduction and Relief Committee Office coordinated emergency responses across the affected cities and counties. Special attention was given to residents near rivers, unstable slopes, and other sites vulnerable to flooding or ground instability.
Floodwaters and landslides caused damage to roads and disrupted electricity and communications services in areas such as Baoting and Wuzhishan. Rescue teams accessed affected communities where routes remained passable. Utility crews began restoring power and water supplies as rainfall lessened and floodwaters started to recede. Emergency personnel also checked isolated settlements and transportation routes while local governments carried out damage assessments and relief operations.
Recovery efforts underway as rainfall subsides
On September 15, Hainan lifted its Level III heavy-rain warning after rainfall decreased significantly across much of the province. Officials announced that the extreme weather event had mostly concluded, enabling more communities to begin recovery activities. Some schools resumed classes where conditions allowed. Crews worked to clear mud, reopen roads, and repair damaged infrastructure as residents started returning to areas deemed safe.
During the emergency, the Ministry of Emergency Management activated a Level IV national disaster relief response for Hainan. Provincial authorities also downgraded the island’s flood and typhoon emergency response from Level II to Level III on September 14. Five working groups were dispatched to affected zones to support local rescue and recovery efforts. Work continues to repair roads, restore utilities, and address the impacts of several days of heavy rainfall on communities.
