Summary

Heavy rainfall beginning Thursday has caused widespread flooding across Bangkok and surrounding provinces in Thailand. All 50 Bangkok districts were declared disaster areas. Rainfall totals ranged from approximately 300-330mm between Thursday and Sunday. Nearly 4,900 residents were evacuated to shelters, with approximately 52,000 households affected in Bangkok alone. Samut Prakan province was the worst-affected area with over 124,600 households damaged. The flooding was caused by the city's drainage system being overwhelmed; the Chao Phraya River remained 40cm below its banks and was not the immediate threat. At least eight deaths were reported across Thailand, with damage estimated at approximately US$320 million affecting more than 580,000 homes across Bangkok and 41 surrounding provinces. The Thai government declared September 28-29 as special public holidays in Bangkok and three neighboring provinces (Nonthaburi, Pathum Thani, and Samut Prakan) to facilitate relief efforts and reduce travel impacts. Thai Airways reduced flights by 30% due to airport disruptions. Authorities worked to drain floodwaters, with estimates of 2-3 days needed if rainfall ceased. Some residents reported water levels exceeding those of the 2011 floods.
