Thailand
7 July 2025 - 13 July 2025The low-pressure cells covered upper Vietnam in the first half of the week. In addition, the monsoon trough lay across the upper northern and upper northeastern regions of Thailand, as well as Laos and upper Vietnam, during the second half of the week. At the end of the week, a low-pressure cell moved to cover the upper northeastern region. Moreover, the moderate southwesterly monsoon prevailing over the Andaman Sea, Thailand, and the Gulf of Thailand strengthened during the latter half of the week. These conditions led to rainfall in several areas of upper Thailand, particularly in the northern and northeastern regions, which experienced heavy to very heavy rainfall for most of the week, with flooding reported in some locations. In the southern region, abundant rainfall was reported, mainly along the west coast.
