I would be really interested to know how this can occur? :?
The strong winds and waves are likely over the Andaman Sea 2-3 meters high and the Gulf with about 2 meters high and above 3 meters high in thundershower areas.
The same with this "prediction". The strongest wind shown on the surface synoptic chart in the Andaman Sea is a roaring 5 knots! Further south in Indonesia it manages to get to 20 knots, which still will not produce waves of 2-3 metres.

The Monsoon that isn't!
Along with other parts of the World, the weather is not behaving as it should. Although there have been record rains in northern China and Japan, it is proving to be a very weak Monsoon nearer the equator. Weak surface winds from India to Thailand are not gathering up much moisture. There is some dispute about what is causing it, with El Niño being blamed by some. There has never been a solid prediction concerning El Niño this year, but it does not appear to be the problem that it has been in the past. Bear in mind that the SW Monsoon arrives here from India.
…………………………………………………………………………………………………………………………………………………...

El Niño Expected to Go Away; Monsoon May Strengthen in Coming Weeks

https://weather.com/en-IN/india/monsoon ... -forecasts

El Niño—the bad boy of global weather—has been playing hide and seek for quite some time now. While forecasts suggested the formation back in August 2018, the confirmations came only by February 2019. After mixed signals of weakening and strengthening over the past six months, El Niño conditions in the Pacific Ocean are (finally) expected to die down in July or August.

The El Niño–Southern Oscillation (ENSO) is periodic yet erratic variation in winds and sea surface temperatures over the Pacific Ocean that affects the global weather patterns. The positive phase of ENSO is the El Niño, which is correlated with lower-than-normal rainfall amount and later-than-normal arrival of monsoons in India. The ‘weak’ El Niño was expected to affect this year’s southwest monsoon, which indeed made onset a week late in Kerala.

The US weather agency, National Oceanic and Atmospheric Administration (NOAA), in its latest advisory released Thursday, has confirmed that a transition from El Niño to ENSO-neutral is expected in the next month or two. The Australian Bureau of Meteorology (BOM), on the other hand, declared during June last week that ENSO has turned neutral and is expected to remain so at least till November.

Sea surface temperature anomalies during El Niño reduce moisture-incursion to the Indian subcontinent during the monsoon season. Therefore, El Niño results in lower-than-normal monsoon rainfall in India. In June, India witnessed a whopping 33% deficit in the monsoon rainfall owing to multiple factors including delayed onset, the formation of cyclone over Arabian sea and the lingering El Niño over the Pacific ocean.

More rains expected in the south

Forecasts suggest that after a brief break till July 17, the likely formation of a low-pressure area over the Bay of Bengal may strengthen the monsoon rainfall across India. While different agencies differ on the location and trajectory of the low-pressure, the IMD forecasts above normal rainfall across the five states in southern India from July 18 to 24.

“Beginning next week, a wetter period is forecast in the southern and western states. However, the rainfall will remain well below normal for central and northern India. Moving forward, a pulse of moisture is expected to move between north and central India from last week of July till the first week of August, and after that, it may ease down again. As there exists a deficit in monsoon rainfall so far, especially central India will benefit from this wet phase”, says Leon Brown, Head of Global Meteorological Operations at The Weather Company.

Mekong water level lowest in 10 years

https://www.bangkokpost.com/thailand/ge ... n-10-years

NAKHON PHANOM: The water level in the Mekong river is the lowest level in 10 years, according to local media reports.
The water level, 2.60m, is about 10 metres below the spill-over point on the Mekong river bank, which is 13m high. In the same period last year, the water was about 12m high.

The meteorological station in Nakhon Phanom revealed that this year's average rain volume has been about 90 millimetres, much lower than the roughly 300mm recorded last year.

Moreover, a long dry period during this year's rainy season has brought a severe drought, lowering the water in the Mekong to a critical level.

The drought has also caused water in the Mekong's tributaries such as Nam Kam, Nam Oun and Nam Songkhram to be about 20-30% of their holding capacities. The problem is certain to get worse unless rain starts.

The provincial irrigation office has begun to conserve water at all 13 reservoirs in the province's 12 districts in a preparation to provide drought relief.

Farmers outside the irrigated zones have been told to reduce farming activities to avoid damage from the drought.

Dept warns of worst drought in decade

https://www.bangkokpost.com/thailand/ge ... -in-decade

The Meteorological Department (MD) says Thailand is going to experience the worst drought in a decade, as average precipitation across large swaths of the country has fallen far short of the monthly average.

Kornrawee Sitthichiwapak, the MD's deputy director-general, said downpours this rainy season were far below average, particularly in the North and Northeastern as well as in the Central Plains -- all of which are important crop growing regions.

"The country's overall rainfall is the lowest in a decade," she said.

Ms Kornrawee said this season's storms -- including Tropical Storm Mun -- were much less powerful than in previous seasons, bringing much less rain to the interior part of the country.

"As such, farmers will have to wait until late August or early September for heavy rain to fall," she said.

The lack of rain has affected water reserves across the country.

Water levels in large reservoirs stood at about 38% in the North, 33% in the Northeast, 22% in the Central Plains, 35% in the East, 67% in the West, and 60% in the South, according to figures released by the ONWR.

The lack of heavy rain has seen four medium-sized reservoirs in Nakhon Ratchasima completely dry out, according to the 8th Royal Irrigation Office.

The empty reservoirs have prompted the Office of National Water Resources (ONWR) to speed up efforts to mitigate the impact of the looming drought.

Samroeng Saengphuwong, the deputy ONWR secretary-general, convened a meeting in Buri Ram -- attended by officials from Nakhon Ratchasima, Surin, Buri Ram, Si Sa Ket and Ubon Ratchathani -- to discuss the situation.

Officials also proposed measures to lessen the drought's impact on local residents.

"Prime Minister Prayut Chan-o-cha has instructed the ONWR and other related agencies about the importance of helping those already suffering from water shortages, who will be even more affected by the drought," said Mr Samroeng.

According to Mr Samroeng, the northeastern region has only 4.3 billion cubic metres of water reserves left in its dams and reservoirs, which equates to about 33% of its maximum capacity.

"Seven large dams in the region now have less than 30% of their maximum capacity," he said.

Nation braces for torrential rain

https://www.bangkokpost.com/thailand/ge ... ntial-rain

Parts of the South, the East, the Central Plains and Bangkok and surrounding provinces are being warned of “heavy” and “extremely heavy” rain from Wednesday until Friday.

In announcement issued on Wednesday, the Meteorological Department said a strong southwest monsoon in the Andaman Sea, the South and the Gulf of Thailand is bringing torrential rain to these parts of the country.

People living in these affected areas have been warned to brace for possible flash floods, while fishing trawlers have been cautioned against going out to sea during the same period, the department said.

Waves will rise between 2 metres and 3 metres during the period, the department said.
Provinces included in the torrential rain warning are Ratchaburi, Nakhon Pathom, Samut Songkhram, Samut Sakhon, Bangkok, plus provinces including Chanthaburi, Trat, Chumphon, Surat Thani, Naknon Si Thammarat, Phatthalung, Songkhla, Pattani, Yala, Narathiwat, Ranong, Phangnga, Phuket, Krabi, Trang and Satun.

The department also advised those who are planning to travel to the Philippines and Taiwan to closely monitor weather updates before going as tropical storm Danas has developed in the Pacific Ocean and is expected to pass upper Luzon in the Philippines to Taiwan soon.

The storm warning ironically came soon after the department said that that Thailand is facing its worst drought in a decade, with rainfall below average so far this year.

Tap water drying up, crops withering in arid fields

https://www.bangkokpost.com/thailand/ge ... rid-fields

Worst drought in 40 years in North, Northeast

People in the northern and northeastern regions are facing the worst drought in 40 years, with crops withering and tap water on the verge of drying up in some areas.

A Nakhon Ratchasima, a provincial waterworks official on Friday warned of a looming shortage of tap water in areas where levels in local reservoirs are dropping.

“This is the longest the rains have held off in 40 years,” said Prayat Raksachat, who operates a piped water system in Thap Kwai, a village in tambon Chiwan in Nakhon Ratchasima’s Phimai district.

“The tap water supply is currently at only 1% of capacity,” Mr Prayat said.

He was worried how the village of 500 residents would find water for daily use and consumption.

Throughout much of the Northeast, in areas without irrigation, rice crops have wilted and turned yellow, instead of the healthy green normal at this time of year, and will soon die off unless there is substantial rain.

Chaiyong Chaiburi, a farmer in tambon Chiwan, said arid weather conditions have forced him to reap all the rice plants on his 50 rai of paddy.

“I used it to feed my buffaloes,” he said. “It’s better to see the rice put to good use instead of just withering away and dying.”

In Chaiyaphum province, residents of Muang district have resorted to an ancient ritual known as hae nang maeo, or the cat procession, in a desperate attempt to appease the gods and have them dump rain on the arid areas.

By tradition the villagers throw water on cats being carried around in cages. It is believed a cat's cry will be heard by the Gods as a request for rain.

“But we know now that treating cats that way is cruelty to animals, so we use toy cats instead,” Songkhram Wonsikhai, a 75-year-old local wiseman, said.

The situation is the northern region is equally worrying.

The water level in the Mae Kuang Udom Thara Reservoir in Chiang Mai province has fallen to only 12% of its capacity -- worse than the level seen during the drought crisis in 2015, Chensak Limpiti, director of Mae Kuang Udom Thara Reservoir, said.

Deputy Agriculture Minister Prapat Pothasuthon said the ministry will keep the farmers updated about the drought and weather conditions.

"Despite the severe conditions, we need to tell the truth to farmers. They must know whether their plants will survive or not," he said.

Thailand is not the only Asia country suffering from drought during the rainy season, Smith Thammasaroj, former chairman of the National Disaster Warning Centre, said. India, Pakistan and Myanmar face a similar situation, because the humidity from the North Pole has not come south as it normally should have.

This will mean less or even no rainfall until September, he said.

The Meteorological Department said that the delay in the rains was partly caused by a warmer Pacific Ocean, which will decrease rainfall in the East and Central Plains, including Bangkok, by 5% until next month.

Prayut orders army to be on alert

https://www.bangkokpost.com/thailand/ge ... e-on-alert

Severe drought in North raises concerns

Prime Minister Prayut Chan-o-cha has instructed the armed forces to provide help in areas affected by drought, a situation which may be made worse by the test run of Xayaburi dam on the Mekong River in Laos.

Gen Prayut, also the defence minister, expressed "grave concern" over the situation in the North and the Northeast, assistant defence spokesman Phatchasak Patirupanon said yesterday, though the premier did not specifically point to the impact from the dam test.

Eight provinces located along the river in the two regions -- Chiang Rai, Loei, Nong Khai, Beung Kan, Nakhon Phanom, Mukdahan, Ubon Ratchathani and Amnat Charoen -- are likely to bear the brunt if the hydroelectric trial, which started last Monday, continues until July 29 as planned.

Much of the North and Northeast have become arid due to a lack of moist air from the North Pole and Pacific Ocean, known as the El Nino effect. (not sure how moist air from the north pole gets to Thailand, and there is no El Nino established this year)

On Friday, the Office of National Water Resources wrote to the Lao government, asking it to suspend the test.

The 1,260-megawatt Xayaburi dam, located just south of Luang Prabang in Xayaburi province, is scheduled to begin churning out electricity this October, with the Electricity Generating Authority of Thailand (Egat) being its major power buyer. (well, isn't that ironic!)

"The armed forces have been told to look for drought-affected areas so it can provide immediate help," Col Phatchasak said, referring to Gen Prayut's order.

Relief measures include sending army water trucks to drought-stricken areas, Col Phatchasak said. The air force will also work with agriculture officials to make artificial rain near reservoirs, which continue to suffer from low water levels.

"Rain is now a past memory," Athit Phanasun, chief of a Nong Khai environmental group, said after many areas in his province have seen no rain for over a month even though it should have been a soaking wet period.

Nong Khai's Muang district on the side of the Mekong now sees its riverbank extend almost to the middle of a section of the river, following the recent rapid decrease in its water level, he said.

The Xayaburi dam test will only make things worse, Mr Athit added.

In Chiang Rai, residents are complaining over a drop of water level in the Mekong. They are also worried about the dam operations upstream in Laos.

"Water levels are even lower than they usually get during dry season," tourist boat operator On Unsaeng said.

Farmers in Nakhon Ratchasima are also suffering. Their rice crops in paddy fields covering almost 200,000 rai in Phimai district are wilting and dying as the severe drought takes a toll.

Governor Wichian Chantharanothai yesterday reported that water sources in the district are running dry.

"Unless it rains this month, the crops will be decimated," said the governor, adding water trucks had been sent to drought-hit areas to provide temporary relief.

Mekong river in Nakhon Phanom "lowest in almost 100 years"

https://www.bangkokpost.com/thailand/ge ... 100-years-

NAKHON PHANOM: Water in the Mekong river in this northeastern border province is only about 1.50 metres high, possibly the lowest level in almost 100 years, according to local media reports.

As the dry spell continues, the water in the Mekong river has dropped by about 10-20 centimetres per day. It is now only about 1.50m high, about 11 metres below the spill-over point on the river bank.

The water level is now so low that a large rock on which a Buddha footprint is engraved has emerged in the middle of the river despite the fact that it is now during the rainy season.

The rock with the Buddha footprint in tambon Woen Phra Bat of Tha Uthen district, believed to be more than 2,000 years old, which is highly revered by the peoples on both sides of the river, could usually be seen only in the dry season between March and April.

The water levels in all Mekong river's tributaries including Nam Oun, Nam Songkhram and Nam Kam are also very low. Water levels in major reservoirs in the province's 12 districts are now only 10-20% of their capacities. Rice fields in areas they run through are now without water.

Farmers said their crops would die if there is no rain at all in a week.

Lai Sripeng, a 68-year-old farmer of tambon Woen Phra Bat, said it is the first time in her life to see the rock with the Buddha footprint in the Mekong river during the rainy season. This unnatural phenomenon is a sign that this year's drought would be critical, she said.

Pasak Jolasid dam now less than 5% of capacity

https://www.bangkokpost.com/thailand/ge ... 5#cxrecs_s

LOP BURI: Pasak Jolasid dam in tambon Nong Bua of Patthana Nikhom district now has only 46 million cubic metres of water left, or only 4.82% of its full capacity of 960 milllion cubic metres, according to media reports.

Supachai Manokarn, the dam's director for water distribution and maintenance, said water in the dam is now at a critical level after a long period without rain.

Despite the small amount of water remaining in the reservoir, it is still necessary for the dam to discharge water to communities below for consumption and to maintain the ecological system.

The 10th irrigation zone of the Royal Irrigation Department has continued to supply water through a pipeline system to about 30,000 rai of land in Sa Bot, Khok Charoen and Khok Samrong, but at a much-reduced rate: 8,333 cubic metres per day, down from about 20,000 cubic metres.

As the water level in Pasak Jolasid dam drops, old communities -- including temples that have been underwater since the construction of the dam -- have re-emerged, becoming a tourist attraction during the drought.

Free-range duck raisers also hit by drought

https://www.bangkokpost.com/thailand/ge ... by-drought

PHITSANULOK: The ongoing dry spell has affected not only rice-growing farmers but also free-ranging duck raisers who say they are producing fewer and smaller eggs than usual, according to farmers in this central northern province.

By tradition, the raisers herd their ducks in droves across rice fields in the rainy season when the fields are full of rainwater and become a source of edible natural food, particularly golden apple snails.

Since the snails gobble up rice seedlings, rice farmers are more than happy to let duck raisers herd their poultry across their fields.

But the situation is different this year. Most of the rice fields in Phitsanulok are drying up due to a long rain break, leaving nothing edible for the ducks to forage.

Kiatchai Manowan, 42, a farmer in Phitsanulok's Bang Rakam district with a large brace of about 2,000 ducks, said the drought has deprived his poultry of natural food. Aggravated by the unusual heat, the ducks have become tense and are eating less, he added. They are producing fewer eggs, and those eggs are smaller in size than usual.

As a result, the farmer said, he has had to spend more on food and supplements for his poultry, raising his investment costs.

Well, the weather gods are having a big argument over Bangkok right now. Much banging and flashing. But the strange thing it is the storm has come in from the east. Some rain but it seems to be passing over very quickly. :?
