End of September and beginning of October, Tropical Storm Dianmu flooded the area, causing flash floods and the Activation of the International Disaster Charter. Tropical Storm Kompasu followed, bringing more heavy rains to Vietnam, Laos, Cambodia and Thailand.
Beginning of October, historical sites in the province of Phra Nakhon Si Ayutthaya, which is home to many temples and ruins, was inundated by the Chao Phraya River. Thailand’s State Railways have also temporarily suspended some train journeys.
