All eastern and Andaman coastal provinces have been placed on alert by the Disaster Prevention and Mitigation Department over possible flash floods and rapid currents from mountainous areas.
The department announced on Monday the alerts for all eastern provinces and all provinces on the Andaman Sea, warning they should brace for flash flooding and runoff. Kanchanaburi, Ratchaburi, Phetchaburi, Prachuap Khiri Khan are also on the watch list, it added.
Heavy rain pounded northern and northeastern provinces over the weekend causing floods in nine provinces. Phetchabun's Bung Sam Phan district, Kalasin's Kamalasai district and Buri Ram's Muang district were among the hardest-hit areas.
The Meteorological Department on Monday also warned of flooding and runoff in all areas close to the mountains where downpours took place. Landslides are also possible in the areas where soil no longer absorbs rain water.
