Severe flooding in northern Thailand, caused by Typhoon Yagi and subsequent heavy rains, has resulted in at least four deaths and left thousands stranded, primarily in Chiang Rai and Chiang Mai provinces, affecting about 9,000 households. Prime Minister Paetongtarn Shinawatra confirmed the fatalities, with rescue operations underway, including helicopter evacuations for those trapped in inundated areas. The disaster has also had significant impacts across the border in Vietnam, where at least 143 people have died, prompting evacuations due to swollen rivers. The Thai government has mobilized military and medical personnel to assist affected families, while warnings of continued heavy rains raise concerns for potential further flooding. Local authorities have reported instances of residents trapped without food and water, highlighting the urgent need for aid. Experts note that climate change may be exacerbating the intensity of these weather patterns, leading to more devastating floods during the monsoon season.
