07 November 2025 - 13 November 2025Typhoon “KALMAEGI (2525)”which made landfall in Binh Dinh, Vietnam subsequently weakened into a tropical storm over Cambodia and a tropical depression over Laos. It then moved into Thailand at Sirindhorn District, Ubon Ratchathani province at 09:30 a.m. on 7 Nov., before became an active low-pressure cell over Si Sa Ket province at 05:00 p.m. on the same day. The remnant of storm continued moving across the northeastern and northern regions during 8-9 Nov. and then covered Myanmar on the following day. Additionally, the weak high-pressure area covered the northeastern and northern regions, while the easterly and southeasterly winds prevailed over the lower northeastern, eastern and lower central regions in the second half of the period. Moreover, the moderate high-pressure area from China extended its ridge to cover the northeastern region on the last day of the period. These conditions caused cool weather in several areas of the northern and northeastern region, with rainfall mainly in the first half of the period, whereas the central and eastern regions experienced rainfall almost the period, resulting in flooding in some areas. For the southern region, the rather strength southwesterly wind prevailed over the Andaman Sea and southern region in the first half of the period and then the westerly and northwesterly winds blew over the Andaman Sea, southern region and the Gulf of Thailand, resulting in rainfall throughout the period.
