The country has been warned of possible intense downpours today by the Thai Meteorological Department (TMD), affecting 42 major provinces across Thailand, including Bangkok. Residents are being cautioned of sudden flash floods. At 5am today, the TMD forecasted a 24-hour weather change with the intrusion of monsoons from the north and northeast. These monsoons are heading towards a low-pressure area along the Vietnamese coast, reinforcing the southwest monsoon that currently covers the Andaman Sea, Thailand, and the Gulf of Thailand.

 

This combination of weather patterns is expected to increase rainfall across the country with the possibility of heavy rain in some areas. Citizens in these vulnerable areas are advised to be conscious of dangers from heavy rain and accumulated rainfall, which might lead to sudden flash floods and forest runoff. Coastal areas along the Andaman Sea and the Gulf of Thailand can expect waves as high as 2 to 3 metres. Areas experiencing thunderstorms could see waves higher than 3 metres. Local fishermen along the Andaman Sea and the Gulf of Thailand are urged to navigate with caution and avoid areas experiencing thunderstorms. Small boats should avoid venturing from the coast.

 

The weather forecast for Thailand from 6am today until 6am tomorrow predicts strong rainfall and thunderstorms in the north, affecting 70% of the region, with some areas expected to experience heavy rain. Temperatures will vary between 23 and 26 degrees Celsius, with a high of 31 to 35 degrees Celsius. The southwestern winds are blowing at a speed of 10 to 20 kilometres an hour. In the northeast, there is a 70% chance of rain and thunderstorms. Heavy rainfall is expected in parts of the provinces Loei, Nong Bua Lamphu, Nong Khai, Bueng Kan, Udon Thani, Sakon Nakhon, Nakhon Phanom, Mukdahan, Amnat Charoen, Si Sa Ket, and Ubon Ratchathani. Temperatures will range between a low of 24 to 26 degrees Celsius, with a high of 31 to 34 degrees Celsius. The prevailing wind is blowing southwest at 10 to 20 kilometres per hour, reported KhaoSod.

Started raining heavily here (Rayong) around 9pm last night, and hasn't stopped since.

Looks like I can escape gardening duties this weekend.

Isn't Rayong,or Rain-on as someone once said, known as the wettest place in Thailand .

I am in Lopburi province, so far this month we have had 21 mm of rain, now corn crops are dying due to lack of rain, and some rice crops are looking a bit dry, but most are not even planted yet, no rain, things running well late this year.

The wettest province in Thailand is Trat.

Where in Rayong are you? In downtown Rayong it started around 7 pm and rained all through the night, but it wasn't heavy.

Not sure, tbh. Rayong's 'monsoon season' normally starts late, around September-October. Its a coastal province also, with mountains and a run-off into the sea, so flooding is not (normally) an issue here.

Virtually zero in HH been braced here for months ????

Steady rain for 2 days in Pattaya area, not heavy though... still it was about 4 inches or more. I said to the Mrs we don't get the swarms of termites after the first rains like we used to, and an hour or two later I was rushing to close doors and windows as they swarmed for any lit opening.
