Flooding has affected more than 174,000 families across 25 provinces and all 50 Bangkok districts, with eight deaths reported, Thailand's Department of Disaster Prevention and Mitigation (DDPM) said on Sunday.

As of 6pm on 27 September, flooding had reached 128 districts, 587 subdistricts and 2,500 villages. DDPM recorded 174,803 affected families, or 545,022 people, in the 25 provinces and Bangkok.

DDPM Director-General Teerapat Khachamat said heavy to very heavy rain, combined with water flowing south from northern Thailand into the Central region, had caused the widespread flooding.

Bangkok and Samut Prakan among worst affected

Samut Prakan was the worst-hit area, with 124,678 families affected, according to the department. Bangkok followed with around 52,000 affected families, while floodwater was reported in every one of the capital's 50 districts.

Elsewhere, 13,971 families were affected in Phra Nakhon Si Ayutthaya, 8,716 in Sa Kaeo and 6,385 in Suphan Buri.

The affected provinces are Phitsanulok, Phetchabun, Nakhon Sawan, Uthai Thani, Lop Buri, Sing Buri, Chai Nat, Suphan Buri, Saraburi, Phra Nakhon Si Ayutthaya, Samut Prakan, Pathum Thani, Nakhon Pathom, Nakhon Nayok, Prachin Buri, Chachoengsao, Sa Kaeo, Chon Buri, Rayong, Chanthaburi, Trat, Buri Ram, Chaiyaphum, Nakhon Ratchasima and Surin.

The eight deaths were recorded in four provinces: five in Sa Kaeo, two in Chanthaburi and one in Saraburi.

Rising water warning for central provinces

Water levels were continuing to rise in Chai Nat, Sing Buri, Suphan Buri, Phra Nakhon Si Ayutthaya, Pathum Thani, Nakhon Nayok, Prachin Buri and Sa Kaeo. Levels were falling in several other affected provinces, while remaining steady in some areas.

In Bangkok, water levels were reported as stable with flooding levels receding across most of the capital.

Relief work under way

DDPM said it had coordinated with local authorities and partner agencies to speed up drainage, assist vulnerable people, move belongings to higher ground and distribute essential supplies.

Provincial disaster prevention and mitigation offices have been ordered to assess damage and collect information on affected residents for assistance under relevant regulations.

This is a small chance they simply drowned in flood water.

Yeah but those who needed to get to Emergency with heart attacks, strokes etc, they won't be included in any data

Supposedly SE Asia is having a dry spell now due to the El Niño slosh in the Pacific ocean and in a year or two, the rains will be more intense here.

Or maybe it's all random chance, anytime, ever year?

Anybody know how the Bangkok center city roads are this morning, Monday? Thanks!

How do they know the number is exactly 545,022?

Don't worry the Bangkok governor will have a solution at hand.

They wre probably banking on people forgetting about it in a few days.

So many videos of snakes, monitor lizards and fish in the water

Monitor lizards and fish in the water...Amazing Thailand!!

"disaster prevention and mitigation offices" -- When it comes to prevention, very little is ever done by the government regarding flood prevention. Nothing substantial, in any event. For Bangkok, Tokyo's approach should be followed... See the BBC article entitled:

I was hit by the huge flooding 15 years ago. Hundreds of people died, most of them were electrocuted.

A flood-prone area

any land surface or terrain that is at high risk of being submerged or inundated by water from rivers, heavy rain, or storm surges.

• Low-lying geography

• Poor drainage

• Statistical risk

The worst is the snakes who are sticking their heads out the drains, can't get their body out

Amazing.....as if it would never had happen before.

Rain is always a great excuse for floodings if you don't do anything to protect your people, no flood retention, no flood bypass.

Pathetic

This is a catastrophe of great proportions and is affecting millions of Thai people who just don't need this hassle, expense, and aggravation right now.

No doubt we needed the rain as the reservoirs have been very low, but it was too much rain and it happened too quickly. Very unfortunate.

I bet 10 baht Mabprachan lake is still low as the run off went mostly into the sea

"The Bangkok drainage tunnel project is a large-scale underground infrastructure system designed to rapidly drain floodwaters from flooded areas into the Chao Phraya River. Currently, there are more than 10 tunnels in operation and under construction to improve drainage efficiency and cover high-risk areas."

The Japan flood challenges are not same as Bangkok areas.

There are the upstream dam releases that multiples flood stages down stream.

Down stream river will flood over its banks instead of moving upstream flooding southerly out of the city areas.

"Flooding has affected more than 174,000 families across 25 provinces and all 50 Bangkok districts, with eight deaths reported, Thailand's Department of Disaster Prevention and Mitigation (DDPM) said on Sunday."

The Sathorn district (Bangkok) was minimally affected. From my 6 km city walk on Sunday ,bthe main Sathorn and Silom roads remained clear. Other than getting splashed by a couple of speeding cars, a pleasant walk in the rain. From AI news, the street flooding and drainage backups were typically experienced in the low-lying side streets and connecting routes. The usual culprits, nothing new.

"In Bangkok, water levels were reported as stable with flooding levels receding across most of the capital."

Other than the usual suspects, just another Tuesday. Affected areas well-known to the Bangkok municipalities should be addressed and corrective measures taken.

Provincial disaster prevention and mitigation offices have been ordered to assess damage ..."There's a lot of water out there chief !

and collect information on affected residents ... " most of ther stuff got wet"

for assistance under relevant regulations. ... " in a few weeks we will send in bulldozers to push the garbage out of the way"

hmmmmm. want to bet we have the same discussion next years rainy season ... cause nothing is going to be done about it ....
