The DDPM has issued a flood and rough-sea alert for Ranong, Phang Nga, Phuket, Krabi, Trang and Satun for August 3-7. Waves in the upper Andaman Sea are forecast at 2-3 metres, exceeding 3 metres during thundershowers. Authorities may suspend vessel movements if conditions worsen, and they are told to close caves and waterfalls where hazards are likely and to bar tourists from entering the water. If you run tours, boats, or beach or waterfall businesses, check trip schedules and safety signage now, and keep the 1784 hotline and THAI DISASTER ALERT app in view.
