The Department of Disaster Prevention and Mitigation reports flooding in parts of Bangkok and 26 provinces, mostly the Central Plain, affecting about 3.52 million people. Worst-hit areas include Ayutthaya, Samut Prakan, Pathum Thani, Suphan Buri and Chachoengsao, with some levels still rising while others recede. For a small business, expect disrupted roads, supply deliveries and staff commuting in these areas. Move stock off the floor, confirm alternative transport routes, and check your insurance coverage for flood damage.
