Chadchart urged residents to remain indoors where possible and move vehicles to higher ground. He warned that residents living near canals faced heightened risks as water levels remained high.
The city had initially declared only three districts – Nong Chok, Suan Luang and Khan Na Yao – as disaster areas on September 25. The order was expanded citywide on September 26 as rainfall persisted and flooding intensified.
Further heavy rain was forecast, raising concerns over additional flooding and disruption in the coming hours.
