Thailand Floods Thread

Dark clouds still covered Greater Bangkok on Friday, after heavy rain in the small hours of Wednesday caused widespread flooding that paralysed morning traffic in northern and eastern districts of the capital.

Yes there was, and every one of them came from the east, not the Monsoon! There is still a big high pressure area over eastern China that is blocking the buildup of the SW Monsoon.

Dark clouds still covered Greater Bangkok on Friday, after heavy rain in the small hours of Wednesday caused widespread flooding that paralysed morning traffic in northern and eastern districts of the capital.

Yes there was, and every one of them came from the east, not the Monsoon! There is still a big high pressure area over eastern China that is blocking the buildup of the SW Monsoon.

Are you sure? Every satellite animation I've seen, and the forecasts of rain on the Windy app/website, show the heavy rain and thunderstorms coming in from the west, crossing the Andaman Sea and Myanmar before reaching Thailand.

[Nereus]

I follow what is published on synoptic charts, plus looking out my window in Bangkok I can see where the rain is coming from. Yes, there is some rain in the north of Thailand that is part of the Monsoon, including a Monsoon trough extending right across Thailand, Lao, Cambodia and Vietnam into the South China sea.

The high pressure area in China is blocking the Monsoon from establishing all over Thailand, including Bangkok and further south.

Probably the most accurate weather info in Thailand!

Alert for Chao Phraya basin

https://www.bangkokpost.com/thailand/ge ... raya-basin

The Royal Irrigation Department (RID) on Sunday issued a flood warning for seven provinces in the Chao Phraya River basin as large volumes of water are flowing downstream from the North.

Floods, the worst in 50 years, have already caused widespread damage in Chom Thong district of the northern province of Chiang Mai which has been lashed by heavy downpours.

According to the Disaster Prevention and Mitigation Department, 237 households in seven provinces -- Chiang Mai, Chiang Rai, Lamphun, Tak, Lampang, Mae Hong Son and Kanchanaburi -- have been badly affected by flooding.

Krisada Sripermpan, director of Irrigation Office Region 12, sent a warning letter to seven governors in Chao Phraya basin provinces -- Chai Nat, Uthai Thani, Sing Buri, Ang Thong, Suphan Buri, Ayutthaya and Lop Buri -- to closely monitor the flood situation and inform people of possible inundation.

Floodwater flowing from the North through the Chao Phraya barrage could increase to 300-500 cubic metres per second, causing levels in the Chao Phraya River in Chai Nat and Ayutthaya to rise by 1.5-2 metres.

However, Mr Krisada said Irrigation Office Region 12 would control water levels and prevent harm to agricultural fields. The office will issue a flood alert if water flow through the barrage reaches more than 500 cubic metres per second.

Kriangkrai Chaipiset, chief of Doi Inthanon National Park in Chiang Mai, said the park has closed public access to waterfalls and tourism spots due to the possibility of flash floods and landslides. The heaviest rainfall in Doi Inthanon in 50 years -- 200 millimetres -- was recorded at Kew Mae Pan Nature Trail.

After experiencing flash floods over the past few days, Chom Thong district has seen water levels finally drop.

The situation in four villages in tambon Khuang Pao, which also has endured heavy flooding, is likewise improving.

A northwestern monsoon as well as low-pressure cells moving eastward have brought heavy rain and thunderstorms to the northern and upper northeastern regions as well as many other parts of the country.

Flooding situation worsening in Chiang Rai, waters recede in Chiang Mai

https://thethaiger.com/hot-news/weather ... chiang-mai

The flooding situation in easing in the northern province of Chiang Mai, but getting worse in neighbouring Chiang Rai. That’s according to a Thai PBS World report, which says the levels in several Chiang Rai waterways have been rising steadily since yesterday, as a result of heavy rain on Saturday.

The Chan River has burst its banks in Chiang Rai’s Mae Chan district, with markets and riverside communities flooded. Local officials and workers have built a temporary flood wall to protect the area. Meanwhile, the mayor of Chiang Rai’s Muang district, Wanchai Chongsutthamani, has ordered that the sluice gate be opened, allowing more water to flow into the Kok River, while water pumps are operating around the clock. Officials across 65 communities are currently helping affected residents.

Things are a bit better in Chiang Mai, where the floods have eased. However, some roads remain closed as flooding has made them impassable for vehicles. These include Chotena Road, before it reaches Lanna Golf Club, as well as Highway 2. Drivers are being warned to watch out for mudslides on mountainous roads.

Meanwhile, the route between Chiang Mai and Chiang Rai, prior to arrival in the district of Wiang Pa Pao, is badly flooded, making it impassable for small vehicles. Drivers are urged to use the Wang Nua-Phayao route as an alternative.

The rainfall is not over yet, as Thailand’s Meteorological Department warns of more heavy to very heavy rain today, for both the north and south of the country. The wet weather is the result of a low-pressure cell and monsoon trough over the north and north-east of the country.

Meanwhile, the strong south-western monsoon is affecting other parts of Thailand, including the Andaman Sea and the Gulf of Thailand. Rainstorms and heavy winds can be expected, with the north, north-east, central, and eastern regions, along with the upper south, in for some heavy to very heavy rainfall today.

Floods, the worst in 50 years,

No way!!

Floods, the worst in 50 years,

No way!!

The locals in that area might disagree with you. The reports on the news yesterday showed some pretty wild water in some parts and deep flooding in others.

[HHTel]

Most other reports state the worst in 10 years which is more to the point. People seem to have forgotten the 2011 floods.
Short memories.

[centermid7]

In 2011, me and some 10+ million of my closest friends had a little water in our homes. It was the catalyst that provoked me to move to HH.

Maybe the report was suggesting that it was the worst flooding in that particular area, rather than Thailand in general?

[handdrummer]

Whether it's 10, 50, 5, or 100 yrs., the flooding is still bad and people's lives have been disrupted. Does the number of years matter?

[HHTel]

No it doesn't. But we have suffered much worse in the past.

Who remembers when HH was cut off? I lived in Takiab at the time and it was impossible to get to the town. The road at the south side of the flyover was closed. There were boats being used around the night market area. The army was out in force rescuing people stranded on the rooftops of their homes. Metal bridges being assembled where the road had collapsed on the coast road north of Cha-Am.
The high ground into Takieb was shelter for cattle. Volunteers giving out free water and rice. I was living on credit from the local Mom and Pop shop as it was impossible to get to an ATM.
The extreme flooding stretched from here to Khao Yoi past Petchaburi. The road to Petchaburi by Tha Yang was impassable and temple/country lanes were used.

I think we've all experienced our share of flooding over the years.

[Big Boy]

Interesting. What year was that please?

[HHTel]

October 2003 (I think)

Actually those bridges weren't constructed because the road collapsed. The road was cut through in various places to allow the water out to the sea. Following that the road was rebuilt with several aquaducts to prevent it happening again.
