                  On 24 September 2021, the effects of Tropical Cyclone DIANMU which has gotten weaker and become Tropical Depression moved over Northeastern and Central areas of Thailand causing Thai upper regions to have heavy to very heavy rainfall from 23 September 2021 to 29 September 2021. In the result of the heavy rainfall, flash floods occurred in provinces as follows: Chiang Mai, Lamphun, Lampang, Tak, Sukhothai, Phitsanulok, Phetchabun, Phichit, Kamphaeng Phet, Loei, Khon Kaen, Chaiyaphum, Yasothon, Nakhon Ratchasima, Buriram, Surin, Ubon Ratchathani, Prachin Buri, Sa Kaeo, Chanthaburi, Nakhon Sawan, Uthai Thani, Chainat, Lopburi, Suphan Buri, Sing Buri, Ang Thong, Phra Nakhon Si Ayutthaya, and Nakhon Pathom.There were 197,795 affected households together with 7 deaths and 1 missing person (DDPM).

                   Referring to Geo-Informatics and Space Technology Development Agency (GISTDA) on 28 September 2021, it has been reported with total flood areas of 95,221.28 hectares in the Northern and Central parts of Thailand. The total flood areas consist of provinces as follows: Sukhothai 35,588.96 hectares, Nakhon Sawan 22,319.68 hectares, Phichit 20,526.4 hectares, Phitsanulok 11,905.6 hectares, Kamphaeng Phet 4,113.76 hectares, Uttaradit 434.72 hectares, Uthai Thani 190.88 hectares, Phetchabun 110.88 hectares, and Tak 30.40 hectares. Most of the affected areas are the agricultural areas, lowland areas, and riverbank areas. Since the floods in these areas flow into the lower land of Chaiyaphum province, it causes massive impact in the region, especially on the rice planted areas in Chaiyaphum’s districts such as Mueang Chaiyaphum, Ban Khwao, and Bamnet Narong. Also, it is forecasted that the rice paddy will be affected for around 25,600 hectares while most of the rice is in the flowering and harvesting stages. Thus, the Thai government conducts the field visitto the severe flood-prone provinces such as Sukhothai and Chaiyaphum in order to rescue and aid the affected citizen, prepare the relevant authorities to install barriers and pumps, and proceed with the assessment and close monitoring to this certain disaster.
