Prachuap weather warning issued as rain forecast for most of the week
Prachuap Khiri Khan authorities have issued a weather warning as heavy rain, possible flash floods and strong waves are expected across the province from 14–18 May.
The Prachuap Khiri Khan Provincial Disaster Prevention and Mitigation Command Centre issued the warning on 13 May, following an announcement from the Thai Meteorological Department about heavy to very heavy rain in parts of Thailand and strong waves in the Andaman Sea and Gulf of Thailand.
The warning covers all areas of Prachuap Khiri Khan, including Hua Hin, where thunderstorms are forecast for much of the week.
According to the forecast for Hua Hin, thunderstorms are expected from Thursday 14 May through Wednesday 20 May. The chance of rain is forecast at 40 percent on Thursday and Friday, rising to 60 percent on Saturday and 70 percent on Sunday and Monday. Rain chances are then forecast to ease to 60 percent on Tuesday and 40 percent on Wednesday.
Maximum temperatures in Hua Hin are expected to range from 32C to 34C, with lows of around 24C. Winds are forecast from the west-southwest at 15–19 kilometres per hour.
The Meteorological Department said increased rainfall is being influenced by a fairly strong low-pressure cell over the lower Bay of Bengal, which is expected to move northwards towards the upper Bay of Bengal. The southwest monsoon over the Andaman Sea, Thailand and the Gulf of Thailand is also strengthening.
Officials said the conditions could lead to flash floods, forest runoff, localised flooding and strong waves in Prachuap Khiri Khan.
In the upper Gulf of Thailand, waves are expected to reach about two metres, and more than two metres in areas with thunderstorms. Authorities have been told to monitor coastal areas and warn tourists not to swim during periods of strong waves.
District disaster prevention and mitigation centres, local administrative organisations and relevant agencies have been instructed to closely follow official weather updates, monitor high-risk areas and prepare response measures.
Officials have also been told to pay particular attention to natural tourist attractions, especially waterfalls and caves. If heavy rain creates a risk to visitors, responsible agencies may issue warnings or temporarily close affected areas.
Marine agencies, including harbour offices, naval units and marine police, have been instructed to warn boat operators and passenger services to exercise caution. If conditions become more severe, authorities may consider restricting boats from leaving shore.
The province has also ordered the preparation of temporary evacuation centres, with local agencies asked to ensure sufficient food, drinking water and essential supplies are available if needed.
