Bangkok: The depression in the Gulf of Tonkin is expected to intensify into a tropical storm today, according to predictions from the Meteorological Department. Despite its intensification, the storm, named Narra, is not anticipated to affect Thailand directly. However, it may influence the monsoon trough passing over northern Thailand, maintaining its moderate to fairly strong intensity, which could result in rainfall increases in regions such as Chiang Rai, Phayao, Nan, and parts of upper northeastern Thailand.
According to the latest report from the Tokyo Meteorological Agency's Special Task Force, as of 8:00 AM today, Tropical Storm Narra is centered in the Gulf of Tonkin. With a central pressure of 994 hectopascals and maximum sustained winds near the center reaching 18 meters per second (approximately 65 kilometers per hour), the storm is moving slowly and is expected to remain over the Gulf of Tonkin near northern Vietnam. Despite its proximity, Narra is not predicted to move towards Thailand. Still, the Meteorological Department warns that the storm might strengthen the monsoon trough over northern Thailand, thereby increasing the likelihood of rainfall in the region.
The Meteorological Department indicates that although overall rainfall distribution will decrease from August 22-29, scattered rain remains possible in the northern, upper northeastern, and eastern regions of Thailand. Residents, especially in areas along the Andaman coast of southern Thailand, should be cautious of accumulated rainfall. The department highlights that areas such as Chiang Rai, Phayao, and Nan, which are already experiencing saturated soil conditions, need to be vigilant for potential flooding due to repeated rainfall.
For the period from August 30th to September 5th, preliminary models suggest an increase in rainfall for upper Thailand. The monsoon trough is expected to shift further south, crossing the central part of the country. This shift, along with a low-pressure system covering upper Thailand, could lead to increased rainfall in areas that had previously seen less rain. Residents in upper northern Thailand, particularly in Mae Hong Son, Chiang Mai, Chiang Rai, Phayao, and Nan, as well as those in upper and eastern northeastern Thailand, are advised to stay alert for heavy rainfall and potential flood risks. Continuous monitoring of weather forecasts and warnings from the Meteorological Department is recommended.
