Thailand – Floods in Ayutthaya and Nakhon Phanom

Flooding has affected several provinces in Thailand over the last few days, damaging homes and crops. Disaster management authorities in the country have issued warnings for further heavy rain for the next 4 days.

ASEAN Coordinating Centre for Humanitarian Assistance on Disaster Management (AHA Centre) report that the provinces of Ayutthaya and Nakhon Phanom have suffered flooding over the last few days. Quoting figures from the local Disaster Prevention and Mitigation office in Ayutthaya, AHA Centre reports that flooding has inundated 9,940 houses in six districts.

In a statement on 23 July, Department of Disaster Prevention and Mitigation (DDPM) Director-General Chatchai Promlert said that 23 provinces have suffered flash flooding during July. He added that flooding persists in the provinces of Phichit, Chiang Rai and Lampang, as well as Ayutthaya.

In Nakhon Phanom Province flooding from the Mekong river has affected low land areas especially in southern parts of the province, including That Phanom district and Na Kae district. Floods have damaged almost 1,000 rais (around 160 hectares) of farmland.

Nakhon Phanom Governor Somchai Witdamrong said that continuous downpours have caused the water level in Mekong river to increase. As of 23 July it had reached about 9.3 meters.  Governor Somchai Witdamrong said that the “critical point” is 13 meters.


The Department of Disaster Prevention and Mitigation (DDPM) has warned of heavy rainfall across the country from 24 to 28 July, which could lead to flash floods and mudslides.

The Meteorological Department said that a tropical storm in the upper South China Sea will move upwards to northern Vietnam on 25 July and cover the northern and northeastern regions of Thailand.

Heavy rainfall is therefore expected from 24 July, especially in the northern, northeastern, and eastern regions. Bangkok and its vicinity will experience rainfall from 26 July.
