Flooding in Pua district, Nan province, has affected seven subdistricts, 60 villages, and 8,000 households, with over 16,000 people facing hardship. Two deaths have been reported: the first victim was a bedridden patient living with his mother in Moo 8, Sila Phet subdistrict, Pua district, who was swept away by floodwaters; the second was a male aged 45–50 found by the Petchkasem Foundation near Baan Fai Mool in Paa Kha subdistrict, Tha Wang Pha district.

Flooding has also been reported in Santhisuk and Mae Chrim districts. While water levels in Pua district have begun to recede, the floodwaters are moving toward Tha Wang Pha district, with communities along the Nan River and tributary streams at risk of sudden inundation. A red alert has been issued for Chiang Yuen and Nao Tao villages in Tha Wang Pha district, where water levels continue to rise. The lower Worakon Road near Tha Wang Pha market is now impassable, and four vulnerable patients have been evacuated from Baan Fai Mool.

Nan Municipality is using sandbags and big bags to seal gaps behind the Namloam community to prevent floodwaters from inundating Nan Hospital. Surappol Thiersutr, mayor of Nan Municipality, warned that the monsoon system is expected to bring continued heavy rainfall through August 21, with some areas receiving over 200 millimeters and Pua district over 300 millimeters. Water levels could potentially reach those seen in 2006. The municipality is running pumps at full capacity, sealing weak points, and has opened temporary shelters. The Nakhon Nan Development Bridge is set to close at 4:00 p.m. due to rising water levels. Additionally, Highway 1256 between Pua and Doi Phu Ka National Park has been closed following reports of multiple high-voltage power poles downed and tilted—15 poles have fallen and approximately 23 are leaning.

On August 19, Public Health Ministry Deputy Permanent Secretary Somruk Chungsaman reported widespread flash flooding and riverbank overflow across Nan province. In Pua district, floodwaters have blocked the main Pua-Chiang Klang road, disrupting northern transport routes and affecting many staff at Somdej Phra Yuphrachahospital. The hospital has opened Building 114 to accommodate discharged patients unable to return home, and staff members are also among the affected. In Sansai district, riverbank overflow has forced residents to evacuate, with some still trapped at Ban Sribun Ruean in Phon subdistrict; rescue operations are ongoing. In Tha Wang Pha district, rapid flash floods have impacted Yom and Chom Phon subdistricts, and residents in vulnerable areas have been evacuated, though local health facilities remain operational.

Floodwaters from upstream areas are expected to continue flowing toward Muang Nan and Wieng Sa districts, with ongoing heavy rainfall forecast through August 21. A mass of water is predicted to enter Nan municipality around 10 p.m. tonight. Nan Hospital has already deployed sandbags along vulnerable areas and prepared water-pumping equipment in case water overflows or enters the facility. Health authorities have been ordered to monitor water levels and emergency transport routes in real time, prepare evacuation plans for patients and vulnerable groups, and confirm backup power, water, oxygen, medicine, and medical supply systems. The Regional Health Office 1 has appointed Deputy Provincial Public Health Officer Aphichit Sathaworwiwat as incident commander for the northern zone covering Pua, Chiang Klang, Tha Wang Pha, Thung Chiang, Bo Kluea, and Phra Kiao districts, with emergency transport from the north to use high-clearance military vehicles via the Bo Kluea-Pua alternate route. Shelter centers have been opened in Pua town hall auditorium, Silapat Community School auditorium, Pua subdistrict municipality auditorium, Wat Pa Muead, the entrance to Ban Don Chai, Wornnakorn subdistrict administration office, and Chom Chang and Ban Siao schools. Muang Nan, Phrae, and Wieng Sa areas are to prepare fully, while other areas must have MERT, mini-MERT, JIT, SEhRT, and MCATT teams ready and reserve emergency funds on hand, prioritizing staff safety.

Deputy Prime Minister and Commerce Minister Supachai Panitchpakdi expressed dissatisfaction with Thailand's second-quarter GDP growth rate of 1.9 percent, down from 2.8 percent in the first quarter. The slowdown has been attributed to impacts from the Middle East conflict, which has raised energy prices and living costs for the public.

Exports remain a critical engine for GDP growth. The government projects two-digit growth in export value for the full year, with first-half exports (January-June) totaling approximately 6.6 trillion baht. If conditions remain stable, full-year exports are expected to reach 12 trillion baht. A technical team is scheduled to negotiate the U.S. Agreement on Reciprocal Trade (ART) on August 27-29, with Panitchpakdi following on August 30-September 1.

The government is currently resolving two Section 301 investigation issues: forced labor, which has been concluded, and surplus production, where the U.S. alleges Thai goods are transshipped. Panitchpakdi expressed confidence that Thailand can clarify its position, noting that domestic production accounts for 75-90 percent in three key sectors—rubber, machinery, and automobiles—exceeding the U.S. 60-percent threshold. Currently, 72 percent of Thai goods enjoy U.S. tariff exemptions, and negotiations are underway to secure relief for the remaining 28 percent, particularly agricultural products. Final discussions are scheduled for late August through early September.

Parallel to trade matters, Panitchpakdi instructed preparations to address flooding in Nan Province and neighboring areas, directing the Department of Internal Trade to coordinate with the private sector to ensure adequate supplies of essential consumer goods.

The Natural Resources and Environment Ministry and Thai Kom signed a memorandum of understanding on August 19 to develop technology innovation for managing natural resources and the environment. The initiative, led by the Department of National Parks, Wildlife and Plants, aims to deploy satellite technology, communications systems, geographic information systems, and artificial intelligence to strengthen forest protection, disaster monitoring, and wildlife conservation across Thailand and improve field operations to meet international standards.

Higher officials from the ministry, including Deputy Director-General Veera Khunchaiyarak and Conservation Head Sukhee Boonsrang, attended the signing ceremony. Permanent Secretary Raviwan Boridech emphasized that the partnership represents a crucial shift toward data-driven operations. The technology will not only protect forests and wildlife more effectively but also safeguard ranger safety in remote areas and address air pollution for public health. The department will use IoT systems and advanced geospatial analysis to monitor wildlife behavior in detail, including tracking wild elephants to reduce human-wildlife conflict, monitoring endangered marine species like dugongs, detecting forest fire hotspots, predicting wildfires and cross-border haze, and rapidly detecting illegal encroachment.

Thailand Kom Chief Executive Officer Piyawat Chariyaseritphong confirmed the company will apply its space technology expertise to convert past obstacles into practical solutions, including satellite communications systems, Globalstar technology, and IoT in areas with poor ground signal coverage. The organizations will establish working teams at the regional level, launch training programs to boost staff capabilities in deploying satellite data and AI systems for field command, and maintain the partnership for five years.

CK posted second-quarter revenue of 11.7 billion baht and net profit of 800 million baht, with first-half 2026 revenue of 24 billion baht and net profit of 1.129 billion baht. The company carries a backlog of 146.3 billion baht to be recognized over three to four years.

Nattawut Triwitchayawet, CK's chief executive officer, said second-quarter performance met plan, supported by steady revenue from construction contracting, effective cost management, and growing returns from investments. "We focus on two priorities: controlling costs and managing construction projects on schedule or ahead of schedule," he said. "All projects remain on track and are delivered within the timeframe. Subsidiary companies continue to perform well, giving CK a balanced business structure and better risk diversification."

The company is pursuing new opportunities in government infrastructure projects. Nattawut said CK is ready to bid for large-scale construction projects, leveraging its diverse expertise, experienced workforce, and proven track record. The company's portfolio of integrated infrastructure development businesses also strengthens its position by diversifying revenue streams beyond construction contracting alone.

On August 19, police reported an update in the case of Kan, 40, from the Dong Udom community in Nong Buea Subdistrict, Muang District, Udon Thani Province, who was found unconscious by a water reservoir on August 16. According to a witness, 64-year-old Noi, the group had been drinking to celebrate after a man named Por won 900 baht on a two-digit lottery number ending in 53. During the celebration, Kan became jealous of her 34-year-old husband Por, hitting him repeatedly with a bottle out of fear he might be interested in other women. An intoxicated Kan then fell into the water, and when Por and Noi pulled her out, she claimed she wanted to jump in and die, blaming Por for not listening to her. Later, Por drove to buy more alcohol rather than flee the scene.

On August 19, Deputy Police Lieutenant Adisak Paso from Udon Thani Provincial Police, along with Setha Sukkjai, Deputy District Officer of Muang Udon Thani District, arrested Por, 32, a Lao national, at his wife's residence. Investigations revealed that Por's work visa expired in 2559 (2016)—ten years ago. He now faces charges of assault against his wife, illegal entry, and working with an expired permit. Police plan to deport him.

Por claimed he had worked in Thailand for 16-17 years and met Kan after working in Southern Thailand. On the day of the incident, they won 900 baht on the lottery and bought alcohol to celebrate with two neighbors. When drunk, his wife became extremely jealous and hit him with a bottle. He explained that whenever intoxicated, she would pick fights because she feared he might find another woman, despite his assurances of his faithfulness. The three of them went to bathe in the reservoir, where the drunk Kan fell into the water. Por and the neighbor pulled her out. He then drove to buy more alcohol to continue drinking at home, not to escape. He visited his wife at the hospital the following day and maintained his love for her, though he expressed regret about having to return to Laos, saying he was happy working in Thailand.
