Heavy rains battered Nakhon Si Thammarat, causing flash floods that inundated homes and roads in four districts, with Sisala hardest hit. Water levels are now showing a downward trend. If the rain does not continue, affected routes are expected to reopen for normal traffic.
On 13 Nov 2026, Mr. Ekachai Sunthorn, Deputy Governor of Nakhon Si Thammarat, summarized the flood situation after persistent heavy rains led to rising water levels in many canals, causing flash floods and overflow that flooded homes and roads at multiple locations.
The Nakhon Si Thammarat Disaster Prevention and Mitigation Office, Sisala branch, reported the latest situation covering four districts: Sisala, Tha Sala, Khanom, and Nopphitam. In Sisala District, continuous heavy rain increased water levels in main canals, especially in Village 6, Si Khit Subdistrict, where floodwaters inundated homes and road surfaces.
Meanwhile, on Wat Thepprathanwanaram Road, also known as Wat Khoi Tia, in Village 9, Si Khit Subdistrict, floodwaters covered the roadway and the temple grounds, but vehicles can still pass through with caution.
In Tha Sala District, water levels in main canals also rose. Behind Wat Samosorn in Village 2, Hua Taphan Subdistrict, floodwaters covered low-lying areas. At Khu Khukrit Canal Road in Klai Subdistrict, water overflowed onto the road surface, with vehicles passing cautiously. Additionally, floodwaters entered four households near Soi Talad Athit Pattana 7 in Village 4, Klai Subdistrict.
On Soi Ban Suan Prik, the route to Wat Phra Mai in Village 13, Tha Sala Subdistrict, floodwaters are so high that motorcycles, small cars, and large vehicles cannot pass. Tha Sala Municipality has placed barriers to close the road and warned residents accordingly.
In Khanom District, floodwaters overflowed and eroded a temporary bypass near Samnak Sran Canal Bridge on the Khlong Hloeng-Khanom Road in Villages 5 and 6, Khuan Thong Subdistrict, damaging the route. Authorities coordinated with the Department of Highways to deploy machinery to clear water flow and repair the road, recommending use of completed sections of the main road as detours.
Also, on Ban Lang Road in Village 3, Khuan Thong, there is minor flooding, and near Wat Bang Khu in Ban Klang Alley, water levels are close to overflowing the banks. In Nopphitam District, water in the Klai Canal rose until it overflowed onto a temporary bypass connecting Ban Nam Tok in Village 2, Sakaeo Subdistrict, Tha Sala District, with Ban Ton Phak Kut in Village 5, Nopphitam Subdistrict, forcing temporary road closure for safety.
However, as of 12:00 on 13 Nov 2026, rains have stopped though skies remain overcast. Water in various canals is flowing freely and levels are trending downwards. If no further rain falls, water levels are expected to continue falling and affected routes will reopen for normal traffic. Highway 401 between Surat Thani and Nakhon Si Thammarat remains open.
District command centers are working closely with the Nakhon Si Thammarat Disaster Prevention and Mitigation Office (Sisala branch), local administrative organizations, and relevant agencies to closely monitor the situation. They have personnel and equipment ready to assist residents at all times. Residents in risk areas are urged to follow official announcements closely, especially those in low-lying areas, near canals, and along water-flow routes, to prevent harm from possible recurring floods.
