Thailand floods spread to 25 provinces; Rayong's Klaeng worst in 60 years

What has changed since our last update?

The water is no longer confined to Bangkok. By the evening of 27 September, 174,803 households — more than 545,000 people — were affected in 25 provinces and the capital. Eight people have died in ten days: five in Sa Kaeo, two in Chanthaburi, one in Saraburi. Samut Prakan is worst affected, with more than 124,000 families; Bangkok counts about 52,000 and is beginning to stabilise.

How bad are Rayong and the eastern seaboard?

The Prasae Reservoir overflowed into Krasae Bon, in Rayong's Klaeng district, late on 27 September. The reservoir stood at 331 million cubic metres — 112.60% of its warning threshold — with 24 million cubic metres released daily. Rayong has declared four districts disaster zones: Klaeng, Mueang Rayong, Khao Chamao and Wang Chan. Klaeng Hospital flooded and moved patients upstairs.

• Sukhumvit Road is closed between Khao Din and Prasae.
• Rayong and Chon Buri are on the heavy rain list for Monday 28 September.
• In Banglamung district, Chon Buri, residents call this the worst flooding in 30 years.

Check road conditions before you set out, whether you are travelling Bangkok to Pattaya or heading for Koh Samet through Ban Phe.

Is Bangkok still under water?

Rain over the capital has eased and some roads are back to normal, but several communities remain deep in water. The Bangkok Metropolitan Administration extended its flood disaster declaration to all 50 districts, in force since 25 September. The Chao Phraya Dam is still releasing 1,900 cubic metres a second, unchanged.

• Soi Lat Phrao 101/1 and Soi Ramkhamhaeng 24
• Soi Prasert-Manukit 27

What should travellers expect?

Both Bangkok airports are operating and visitor facilities continue to run, but allow extra time to reach Suvarnabhumi. Since 26 September, ground-handling staff have struggled to get to work on flooded roads: Thai Airways flights were delayed and bags arrived far later than usual. Kanchanaburi, Phetchaburi and Rayong are being watched for possible evacuation after heavier releases from the Kaeng Krachan Dam.

The holidays of 28 and 29 September remain in force in Bangkok, Nonthaburi, Pathum Thani and Samut Prakan, and expressways stay toll-free until midnight on 29 September. It is still the rainy season; our safety guide covers disrupted plans.
