How it started

The situation in Bangkok began with persistent heavy rainfall that started on Thursday afternoon. Over the next two to three days, rain fell almost without pause, quickly overwhelming the city's drainage systems. Bangkok, a low-lying city crisscrossed by canals, is particularly vulnerable to flooding during intense storms. By Friday, the rainfall had already begun to fill major waterways, setting the stage for widespread problems.

Local officials noted that the city had not seen this level of rainfall in years. Homes, shops, and restaurants in lower-lying neighborhoods started reporting water entering their buildings, as the canals swelled and spilled over.

How it unfolded

By Saturday, officials measured accumulated rainfall in Bangkok at nearly 300 millimeters since the storms began, according to the governor. Key canals were filled to capacity, and floodwaters spread across all 50 city districts, with the eastern side of the city particularly affected.

Authorities responded by declaring a citywide flood disaster. This formal declaration gave local organizations emergency powers to coordinate evacuations and deploy resources more quickly. Residents were advised to move vehicles and valuables to higher ground, and evacuation orders were issued for the most vulnerable neighborhoods.

Traffic across Bangkok ground to a halt as roads became submerged, further complicating the work of emergency services trying to reach those in need. Many residents and businesses found themselves isolated by the rising water.

Despite these efforts, water continued to enter homes, restaurants, and other buildings, with images showing flooded streets and stranded vehicles. The situation remained tense as the city braced for more rain.

Where it stands

Bangkok remains under red alert, with the flood disaster declaration still in effect. Emergency teams are working to evacuate residents from the hardest-hit areas and provide support where possible. The eastern districts continue to face the deepest flooding, but all parts of the city are affected.

Forecasters predict further rainfall, which could worsen the situation. Authorities are urging residents to stay alert and to follow evacuation orders as needed, especially in neighborhoods near overflowing canals.

What to watch

The next few days will be critical for Bangkok as additional rain is expected. Emergency services are racing to manage the current crisis and prevent further damage. The effectiveness of evacuations and drainage efforts will determine how quickly the city can recover once the rains subside.
