Severe weather conditions have pushed Taiwan into a major crisis as extreme rainfall triggers flooding, transport breakdowns and emergency alerts across Kaohsiung, Tainan, and Hsinchu. What began as a powerful weather system influenced by Tropical Storm Mekkhala and a strong southwest moisture surge has now escalated into a nationwide disruption event, paralysing daily life and travel movement across the island.

Although the storm system has remained offshore without direct landfall, its outer rainbands have unleashed continuous downpours, overwhelming drainage systems, submerging roads, and destabilising infrastructure. Entire districts are now facing submerged streets, collapsed transport links, and rising emergency evacuations as rainfall intensity shows little sign of immediate relief.

Deadly Flood Surge as Rivers Overflow and Communities Are Engulfed

The flooding crisis has turned deadly in multiple regions, with confirmed fatalities reported in both urban and rural zones. In Kaohsiung City, fast-moving floodwaters swept through residential areas, trapping individuals in sudden surges of water. In Hsinchu County, submerged road conditions and hidden water channels led to further fatal incidents involving stranded vehicles.

Emergency services have also reported missing persons in agricultural zones where floodwaters rose rapidly without warning. Rural farmland areas in Hsinchu have been particularly vulnerable, where sudden inundation created life-threatening conditions for residents working outdoors.

Across the island, flood emergencies have surpassed hundreds of incidents, with rescue teams deployed continuously to respond to trapped households, submerged vehicles, and collapsed roadside infrastructure.

Kaohsiung and Tainan Turn Into Water Zones After Extreme Rainfall Burst

Southern Taiwan has borne the worst impact of the disaster, especially Tainan City and surrounding districts. Rainfall levels exceeding 250 mm within a few hours have been recorded, overwhelming drainage systems and turning residential neighbourhoods into deep-water zones.

In low-lying districts such as Rende, water levels have risen to waist height, forcing urgent evacuations using inflatable rescue boats. Combined rainfall and high tide conditions have created a backflow effect, preventing water from draining efficiently and worsening urban flooding.

In Kaohsiung City, mountainous districts and suburban zones have been heavily affected, with landslide-prone areas placed under strict monitoring. Roads have become submerged or blocked by debris, isolating communities and restricting movement across multiple districts.

Railway Collapse and Transport Breakdown Paralyse Taiwan’s West Corridor

The transport network across Taiwan has suffered severe disruption, particularly along the western railway corridor. Sections of the main north–south railway line operated by Taiwan Railways have been shut down after floodwaters submerged tracks in Tainan City.

In northern regions including Hsinchu and Miaoli, additional railway sections have been affected by mudslides and water accumulation, forcing train diversions and emergency service suspensions. In some locations, debris flows have blocked tunnel entrances, while other stretches have been reduced to restricted single-track operations.

Local branch lines in mountainous regions have been fully suspended due to complete track inundation, cutting off connectivity to smaller communities. Rail authorities continue emergency inspections as water levels remain unstable across multiple sections.

Airports and Flights Hit as Lightning and Storm Cells Disrupt Operations

Air travel has also been significantly affected by unstable weather conditions. While Taoyuan International Airport continues to operate international services with manageable delays, regional airports are facing repeated interruptions.

At Taichung International Airport and Tainan Airport, ground operations have been paused multiple times due to lightning alerts and intense rainfall. Aircraft handling, baggage operations, and runway activities have been temporarily suspended during peak storm activity.

These repeated disruptions have led to cascading delays across domestic routes, with passengers advised to monitor flight status closely before travel. Weather instability continues to create operational uncertainty across regional aviation hubs.

Roads Become Impassable as Landslides and Floodwaters Spread Across Highways

Road transport across Taiwan has entered a critical stage of disruption. Major provincial highways in southern regions have been submerged or blocked by landslides, making travel extremely hazardous.

In Kaohsiung City, multiple districts have reported impassable roads due to deep flooding and debris accumulation. Water levels in some urban areas have reached knee to waist height, making vehicle movement impossible.

Mountainous regions in central and eastern Taiwan, including Hualien County, are under severe landslide threat. Continuous rainfall has destabilised slopes, triggering debris flows and emergency evacuations near hillside communities. Barrier lake overflow risks have further heightened safety concerns in these regions.

Authorities have urged strict avoidance of mountain highways and flood-prone routes as conditions remain unpredictable and dangerous.

Central Weather Administration Issues Widespread Alerts as Rainband Persists

The Central Weather Administration (CWA) has issued alerts across approximately 20 counties and cities, warning of continued heavy to torrential rainfall. Regions including Taichung, Changhua, Nantou, Chiayi, Tainan, Kaohsiung, and Pingtung remain under high-risk warnings.

Yunlin County has been placed under a severe rainfall alert, with forecasts indicating the possibility of extreme precipitation exceeding 350 mm within 24 hours. Such levels of rainfall significantly increase the risk of flash floods, urban inundation, and slope failures.

Meteorological forecasts indicate that while rainfall intensity may gradually reduce in the coming days, unstable atmospheric conditions will continue to affect parts of the island as the system shifts northward.

Nationwide Travel Warning as Infrastructure Struggles Under Pressure

Taiwan’s transport infrastructure continues to operate under severe strain, with rail, road, and air networks all experiencing varying degrees of disruption. Rail closures, road blockages, and airport delays have combined to create widespread mobility paralysis across affected regions.

Emergency authorities continue to prioritise rescue operations, infrastructure repair, and safety monitoring. However, conditions remain highly dynamic, with further disruptions possible if rainfall persists or intensifies.

Travellers across Taiwan face significant uncertainty, with movement between northern, central, and southern regions heavily restricted. Recovery efforts are ongoing, but full restoration of transport services will depend on sustained improvement in weather conditions.

Final Situation: Taiwan Braces for Continued Weather Volatility

The ongoing flood crisis has placed Taiwan under one of its most severe weather disruptions in recent times. With Kaohsiung, Tainan, and Hsinchu experiencing widespread flooding, transport collapse, and emergency conditions, the situation remains critical.

Authorities continue to monitor developments closely as rainfall persists across multiple regions, while emergency teams remain deployed across affected districts to manage rescues, restore infrastructure, and maintain public safety during the unfolding crisis.
