The government has instructed all agencies in four southern provinces to prepare for and monitor flash floods and sudden flooding during 10-15 July. It warned residents to closely follow news updates and information.
On 10 July 2026, Ms. Ploytale Laksamee Sangchan, Deputy Spokesperson for the Prime Minister's Office, said the government is concerned for people in the southern region during 10–15 July 2026. The southwest monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand will strengthen, causing strong winds and waves in the upper Andaman Sea of 2–4 meters high. In areas with thunderstorms, waves may exceed 4 meters. The upper Gulf of Thailand and lower Andaman Sea will have waves of 2–3 meters, and over 3 meters in thunderstorm areas.
Ms. Ploytale stated that from 11–15 July there will be heavy to very heavy rain in some areas, possibly causing flash floods, sudden flooding, waterlogging, and landslides in four southern provinces: Ranong (Mueang Ranong, Suksamran, and Kapoe districts); Phang Nga (Koh Yao, Thap Put, Thai Muang, Takua Pa, and Kuraburi districts); Phuket (all districts); Krabi (Mueang Krabi, Khlong Thom, Ko Lanta, Nuea Khlong, and Ao Luek districts); Trang (Kantang, Sikao, Palian, and Hat Samran districts); and Satun (Mueang Satun, La-ngu, Tha Phae, and Thung Wa districts).
The government, through the Central Disaster Prevention and Mitigation Command (CDPMC), has coordinated with regional disaster prevention centers in risk areas to closely monitor the situation and prepare accordingly. They have instructed officials to continuously track weather, rainfall, and water levels, especially at natural tourist sites such as caves and waterfalls. If risks arise, these sites must be closed to the public. During rough seas, relevant agencies should issue warnings or install signals along coastlines prohibiting tourists from swimming. Mariners, captains, and ferry operators should exercise increased caution while navigating.
If conditions worsen, a complete ban on navigation should be considered. Officials will monitor risk zones and provide assistance to people 24 hours a day. Temporary shelters will be prepared to accommodate evacuees, and relevant agencies, local administrations, village leaders, and community heads must ensure sufficient food, drinking water, and essentials are available at shelters. Provinces are urged to publicize official weather updates closely and warn residents in advance to prepare and strictly follow government recommendations.
