Heavy rain is expected across much of Thailand this week, prompting warnings of flash floods, runoff and dangerous sea conditions.
Chayan Muangsong, secretary-general of the Office of the National Water Resources, said several provinces required close monitoring as heavy rainfall could trigger flooding.
High-risk areas include Mae Hong Son, Chiang Mai, Kanchanaburi, Prachuap Khiri Khan, Phuket and Krabi provinces, he said.
He said Phuket was highlighted as particularly vulnerable because its drainage capacity could be overwhelmed by prolonged heavy rain.
Meanwhile, the Meteorological Department warned that strong south-westerly monsoon conditions and a monsoon trough crossing upper Thailand would bring widespread rain from May 31 to June 6.
Heavy to very heavy rainfall is forecast in parts of the East and along the Andaman coast, with rain expected to cover up to 80% of some southern provinces.
The department warned of possible flash floods, forest runoff and overflowing waterways, particularly near hillsides and watercourses.
Bangkok and surrounding provinces are forecast to experience thunderstorms across 60–70% of the area, with heavy rain in some locations.
