Heavy rain triggered flooding, landslides, and transport disruptions across parts of Laos over the weekend, prompting authorities to warn that more severe weather could follow in the coming days.
On 6 July, the Department of Meteorology and Hydrology said strong southwest monsoon winds continued to affect the entire country, particularly northern and central Laos, bringing widespread thunderstorms and moderate to heavy rain.
Authorities warned that flooding and landslides remain possible in several provinces, including Phongsaly, Houaphanh, Bolikhamxay, Vientiane Province, Champasak, Salavan, Sekong, and Attapeu, and urged residents in vulnerable areas to stay alert.
Early Impact
On 4 July, floodwaters swept away a wooden bridge across the Nam Song River near Tham Lom Cave in Vang Vieng after several days of heavy rain pushed water levels sharply higher.
The same day, a cargo truck skidded off a temporary bypass near Houay Pasouan Bridge in Sepon district, Savannakhet Province, after persistent rain left the road slick, causing lengthy traffic delays along Route 9. No injuries were reported.
In Khammouane Province, floodwater inundated parts of two villages in Thakhek district, where several days of rain combined with poor drainage around Huay Pakximang.
The latest damage follows the first flooding of Laos’ 2026 rainy season on 30 June, when flash floods inundated villages and farmland in Bokeo and Phongsaly provinces.
Forecasters said the unstable weather is expected to continue, urging residents in flood-and landslide-prone areas to monitor official forecasts, move valuables to higher ground, and remain prepared for further flooding if heavy rain persists.
