Severe weather systems are currently impacting Japan and Thailand, leading to forecasts of significant precipitation and potential flooding.

目前嚴重天氣系統正影響日本與泰國，預計將出現顯著降水並可能導致洪澇。

In the Japanese archipelago, the Japan Meteorological Agency has identified the development of dense rain clouds within the Miyazaki and Kagoshima prefectures. This atmospheric instability is attributed to a weather front extending from the Chinese mainland through the Nansei Islands, compounded by a low-pressure system traversing the East China Sea in an east-northeasterly direction. Consequently, the probability of pluvial flooding and terrestrial landslides has increased, with projected 24-hour accumulations reaching 300 millimeters in Shikoku and 150 millimeters in the Amami and southern Kyushu regions.

在日本群島，日本氣象廳已確認宮崎縣與鹿兒島縣內發展出濃密的雨雲。此大氣不穩定現象歸因於一個從中國大陸延伸至南西諸島的天氣前線，並與一個向東北方向穿越東海的低壓系統共同作用。因此，發生雨水淹水與土石流的機率增加，預計四國地區 24 小時累積雨量將達 300 毫米，奄美及九州南部地區則為 150 毫米。

Simultaneously, the Meteorological Department of Thailand has reported the influence of a potent southwestern monsoon encompassing the Andaman Sea, the Gulf of Thailand, and the mainland. The projected trajectory of the monsoon trough—extending from Myanmar through upper Laos to a low-pressure zone in Vietnam—suggests a high likelihood of flash floods and runoff in the Central Plains, the East, and the northern territories. Due to anticipated wave heights of two to three meters, maritime restrictions have been advised for small vessels in the upper Andaman Sea until Friday.

與此同時，泰國氣象局報告指出，強大的西南季風正影響安達曼海、泰國灣及內陸地區。季風槽的預計路徑——從緬甸經老撾北部延伸至越南的低壓區——顯示中部平原、東部及北部地區極有可能發生山洪與逕流。由於預計波高將達兩至三公尺，建議安達曼海北部的小型船隻在週五前採取航行限制。

Both regions remain under meteorological surveillance as heavy rainfall continues to pose risks to infrastructure and maritime safety.

由於強降雨持續對基礎設施與海上安全構成風險，兩地仍處於氣象監測之中。
