Bangkok's governor has extended the flood disaster declaration from three eastern districts (Nong Chok, Suan Luang, Khan Na Yao) to all 50 districts, effective 25 September 2026, because continuing heavy rain is causing waterlogging and traffic problems. The declaration lets government agencies and local authorities act faster across the city. For a Bangkok SME, check flood exposure at your premises, stock and delivery routes this week, and confirm your insurance covers flood damage. Expect slower deliveries and road closures while waterlogging continues.
