Severe Flash Flooding Hits Nan Province, Disrupting Transport

On August 19, 2026, Khaosod Online reported that persistent, heavy rainfall in Nan Province has caused severe flash flooding, particularly impacting the Pua District. The rapid rise of water levels in the Pua and Khwang rivers has inundated residential areas, with some homes in Ban Rong, Pua sub-district, seeing water levels reach nearly the height of the first floor.

For residents and travelers, the situation is critical. Emergency assistance has been requested for families trapped by rising waters, including a household with a six-month-old infant. Transportation infrastructure has been significantly compromised: Highway 101 (Pua-Chiang Klang route) is currently impassable for all vehicle types due to flooding. Furthermore, Highway 1256 (Pua-Bo Kluea route) is inaccessible after a bridge sustained damage and was severed by the currents.

Travelers planning to visit or transit through these areas should expect major delays and potential isolation. It remains to be confirmed how long these road closures will persist and the full extent of the damage to local infrastructure. Authorities are monitoring the situation as water levels continue to fluctuate. Those currently in the region are advised to stay informed through local updates and prioritize safety as rescue operations continue.
