Nakhon Nayok recorded 274 millimetres of rain, the highest figure in the latest regional rainfall report, as Thailand’s Office of the National Water Resources (ONWR) warned at-risk communities to remain alert for flooding and other rain-related hazards through September 30.
The nationwide water situation reported at 7am on Sunday (September 27) highlighted risks to flood-prone urban communities and areas where accumulated rainfall has raised the likelihood of flooding.
Heavy rain persists in western Central region
Western areas of the Central region are forecast to see heavy rain in many locations on Sunday, with very heavy rain possible in some places. Rain in Bangkok, nearby provinces and the East has begun to ease, although showers are expected to continue, with isolated heavy rain still possible.
People travelling or working in areas prone to flooding or waterlogging are advised to monitor official notices and road conditions before setting out.
Regional rainfall data showed the highest readings in each region at 122mm in Kamphaeng Phet in the North, 78mm in Nakhon Ratchasima in the Northeast, 158mm in Bangkok in the Central region, 274mm in Nakhon Nayok in the East, 202mm in Kanchanaburi in the West and 123mm in Ranong in the South.
Reservoirs reach 76% of nationwide capacity
Reservoirs nationwide held a combined 61.013 billion cubic metres of water, equivalent to 76% of total storage capacity. Of this, 36.894 billion cubic metres, or 65%, was usable water. The West recorded the highest reservoir storage level at 88%, followed by the East at 80%, the North at 70%, the South at 69%, the Northeast at 64% and the Central region at 62%.
Chao Phraya water levels remain below banks
In the Chao Phraya River basin, data recorded at 6am showed water levels at Banphot Phisai and Chum Saeng stations in Nakhon Sawan at 2.68 metres and 2.12 metres below their respective banks, with both remaining broadly stable.
At the Nakhon Sawan city station, water was flowing at 1,846 cubic metres per second, while the river remained 3.39 metres below the bank. The Chao Phraya Dam was releasing water at a rate of 1,950 cubic metres per second.
Flood risks remain across 30 provinces
ONWR has called for continued vigilance in risk areas across 30 provinces, including Bangkok and surrounding provinces, as well as parts of the Central, Western and Eastern regions. Heavy and accumulated rainfall could trigger flash floods, forest run-off, waterlogging and landslides between September 26 and 30.
Rainfall across Thailand is expected to ease from September 28 to October 2, although isolated heavy rain remains possible in western parts of the North and the Central region.
