Flash-flood warning issued as downpours forecast to continue
Continuous rainfall and isolated downpours are likely in most of the country on Sunday, with isolated very heavy rainfall possible in the North and the Central regions, the Meteorological Department forecast.
Temperatures will range from 26 to 35 degrees Celsius, it said.
It warned that severe weather conditions may cause flash floods near foothills and overflowing waterways in low-lying areas.
A strong monsoon trough lies across the North, the upper Central and the Northeast of Thailand, while a low-pressure zone covers Myanmar and a moderate southwest monsoon spans the Andaman Sea and the Gulf of Thailand, the department said.
Moderate winds in the upper Andaman Sea and the upper Gulf of Thailand will see waves range between one and two metres in height, and exceed two metres in height during thundershowers. In the lower Andaman Sea and lower Gulf of Thailand, waves will be about one metre high and about two metres high in thundershowers. All ships should proceed with caution and avoid thundershowers, the department warned.
