The most severe flooding in over 50 years is slowly working its way to the sea, and water levels are gradually dropping in areas that have already been flooded. The remaining affected areas include metropolitan Bangkok and 22 additional provinces: Nakhon Sawan, Uthai Thani, Chainat, Singhburi, Angthong, Ayutthaya, Pathum Thani, Nonthaburi, Lopburi, Sara Buri, Samut Sakhon, Samut Prakan, Nakhon Nayok, Pracheen Buri, Chacherngsao, Suphan Buri, Nakhon Pathom, Kamphang Peth, Ubon Ratchathani, Srisaket, Roi-et, and Kalasin.
Floodwaters are being diverted away from central Bangkok to flow through and around the eastern portions of Bangkok Metropolitan area as they drain to the sea. Flooding is more widespread in the outer Bangkok Metropolitan area. It is unclear how long these conditions will last, and U.S. citizens living in flood-affected areas should follow the advice of local authorities, monitor local media, and refer to the U.S. Embassy web page
In many flooded areas, surface transportation has either been suspended or diverted to other areas. Portions of highways are closed, and bus and train services to and through some flooded areas are suspended or have been diverted. Don Muang Airport in northern Thailand, which typically handles a number of domestic flights, remains closed due to flooding. Flights into and out of Don Muang Airport have either been canceled or diverted to Suvarnabhumi, Bangkok's main international airport. We recommend travelers check with their airlines for additional details.
