Hainan Evacuates 42,000 Amid Record Rainfall

Hainan Province in southern China has relocated more than 42,000 residents from high-risk areas as the island faces its most severe rainfall in recorded history. The extreme weather event is driven by the combined influence of the remnant circulation of a tropical depression that made landfall in Vietnam and incoming cold air masses, resulting in torrential downpours across central, western, and southern regions of the island.

Local authorities issued a Level I red warning for geological disasters on Monday, citing a very high risk of landslides and mudflows in specific areas including Tongshi Township and Xiangshui Township. According to reports from CCTV News, daily rainfall totals in Wuzhishan city reached 429.9 millimeters on Sunday, breaking the local record since observations began and prompting the suspension of classes in at least 13 cities and counties, including Sanya and Wuzhishan.

Reservoirs adjust discharge rates

To manage the surge in water levels, operators of the Daguangba and Gezhen Reservoirs in Dongfang city have increased their discharge rates. Beginning Monday morning, both facilities raised their output from approximately 3,000 cubic meters per second to a range between 4,000 and 5,500 cubic meters per second. These adjustments are intended to maintain safe water levels within the dams while accommodating the continuous inflow from upstream heavy rains.

The intensified discharge has led to rising river levels in downstream areas, particularly in Qionghai city. Authorities have issued strict prohibitions on swimming, fishing, and other water-related activities in and around river channels. Residents are urged to stay away from waterways as the turbulent flow poses significant dangers to those near the banks and embankments.

Regional safety measures expand

Beyond educational suspensions, several municipalities have implemented broader economic and transport restrictions. Wanning city has suspended work, business operations, and ferry services, while also closing tourist attractions. Similarly, Qiongzhong county has staged similar measures in response to the escalating situation. These actions reflect a coordinated effort to minimize public exposure to the immediate hazards posed by the storm's lingering effects.

The emergency management authorities of Hainan Province confirmed that the evacuations were conducted safely as of Monday morning. The response involves multiple agencies working to monitor geological stability and manage infrastructure stress. The situation highlights the vulnerability of coastal regions to the compounding effects of tropical systems and seasonal cold fronts.

Monitoring ongoing weather patterns

Forecasters indicate that the risk of rainfall-triggered geological disasters remains elevated for the next 24 hours. The combination of saturated soil and continued heavy precipitation creates a persistent threat in hilly and mountainous zones. Officials are advising residents to remain vigilant and adhere to local directives regarding movement and safety.

This incident, as reported by sources such as GN auto geopolitics/asia-pacific: South China Sea and local news outlets, underscores the increasing frequency of extreme weather events in the region. The forward focus is on the stabilization of river levels and the assessment of infrastructure damage. The coming days will determine the scale of recovery efforts and the duration of the necessary safety protocols.
