Front line stagnation near Honshu; a linear precipitation zone may occur again in northern Kyushu over the next 11th.

2025/08/10 07:19

The front extends east and west from China to the East Sea of Japan, stagnating near Honshu. A frontal low pressure system has emerged near the Yellow Sea, moving southeast.
In the vicinity of Honshu, warm and humid air flows towards the front and low pressure, making frontal activity more active. A linear precipitation zone occurred in Fukuoka Prefecture late last night on the 9th, and as of 7am, developed rain clouds along the Chugoku region and northern Kyushu have been plagued by the front.



The rain area has already spread from Kyushu to Tohoku, and will rain intermittently over a wide area. Heavy rain with localized lightning or extremely heavy rain, which could lead to heavy rain in similar places. In particular, in northern Kyushu and Chugoku regions, there are areas where the ground has been loosened and rivers are rising due to heavy rain, so even with small amounts of rain, landslides and river flooding are likely to occur.
In northern Kyushu, linear precipitation zones will occur again near Yamaguchi, Fukuoka, Saga, and Nagasaki prefectures, up until the morning of the 11th, and the risk of heavy rain disasters may increase dramatically. Extreme vigilance is required for landslides, flooding of low land, flooding of rivers and flooding.



The front is expected to stagnate near Honshu around the 12th. There is a risk that the total rainfall will increase further in the future, mainly on the Sea of Japan side. Also on the Pacific side of western and eastern Japan, warm and humid air flows towards the front, so there are likely areas where heavy rain and extremely heavy rain are accompanied by thunder in Kanto, Koshin, Tokai, Kii Peninsula, and Shikoku.
Beware of landslides, flooding of low land, rising rivers and flooding. Also be careful of severe gusts of wind, such as lightning strikes and tornadoes.

Linear precipitation zones occur in Fukuoka Prefecture; the risk of a life-threatening heavy rain disaster increases rapidly

2025/08/10 00:43

At around 11:50pm on Saturday, the 9th, the Japan Meteorological Agency released weather information regarding the prominent heavy rain in Fukuoka Prefecture, claiming that extremely heavy rain caused by linear precipitation was continuing in the same location.


From the evening of the 9th, heavy rain areas on the line have been stagnating near the Tsushima Strait, with extremely heavy rain, mainly in the coastal areas, with lightning. At around 11:40pm, it was believed that about 120mm of heavy rain fell in an hour near Shingu Town, Fukuoka Prefecture, and record-breaking short rain information was released.



As of 11:50 pm in Fukuoka Prefecture, landslide warning information has been issued in 14 municipalities, including Kitakyushu City and Fukuoka City.
It is not surprising that a heavy rain disaster could occur at any time, which could be life-threatening. In Fukuoka Prefecture, active rain clouds will be exposed to the night of the 10th, and there is a risk that the rain will increase further in the future. Be very careful of landslides, flooding of rivers, and flooding.


Please check evacuation information from local governments and make sure to ensure safety as soon as possible. If it is difficult to evacuate, try to ensure safety by moving to buildings that are even slightly away from cliffs or rivers, or to high grounds that are less likely to flood.
