Bangkok has been declared a flood disaster zone after two days of relentless rain overwhelmed the city’s drainage system, forcing authorities to evacuate residents across all 50 districts.

Heavy rain over the past 48 hours has filled canals and streets, with water reaching depths that have halted traffic and disrupted daily life. According to the BBC, the flooding has spread from the city centre to the outskirts, affecting thousands of homes and businesses.

"All 50 districts are now under a disaster declaration, signalling the scale of the crisis,"

The rain began late on Monday and intensified over the weekend, saturating the Chao Phraya river basin. The Thai Meteorological Department warned that more showers are expected to fall over the capital on Sunday, potentially worsening the situation.

In the heart of the city, streets that usually bustle with commuters have turned into shallow rivers. Residents have taken to boats and makeshift platforms to avoid standing water, while traffic police have erected barricades to prevent vehicles from driving into flooded zones.

Emergency services have deployed teams from the police, fire brigade and military to assist with evacuations. The Ministry of Interior announced that the Thai Red Cross is providing relief supplies to affected households, and the Royal Thai Navy has been called in to support search and rescue operations.

Officials have urged residents to stay indoors and avoid low-lying areas. The Prime Minister’s office issued a statement reminding the public to follow evacuation orders and to report any life‑threatening situations to local authorities.

Bangkok has long been vulnerable to flooding, with its low‑lying geography and proximity to the Chao Phraya river. The city’s drainage infrastructure, designed for a certain rainfall threshold, has been strained by increasingly intense weather events linked to climate change. Historically, floods have disrupted transport, caused property damage and led to economic losses amounting to billions of baht.

The current flood has already caused significant disruption to the city’s transport network. Key roads and railway lines are closed, and public transport services have been suspended in several districts. Businesses in commercial zones report halted operations, and many workers have been stranded at home or in temporary shelters.

Authorities are monitoring rainfall closely and have set up additional flood barriers along vulnerable stretches of the river. Rescue teams remain on standby to assist anyone trapped by rising waters, and a coordinated effort with local NGOs is underway to provide medical care and basic supplies to displaced residents. The situation is expected to evolve as the weather forecast predicts further rainfall over the coming days.
