Due to the influence of the autumn rain front and other factors, rain clouds developed over Kyushu and the Chugoku region. In Nagasaki and Kumamoto prefectures, a linear rainband formed before dawn, and extremely heavy rain was observed.

On the 10th, there is a risk of heavy rain over a wide area from northern to western Japan. In Nagasaki and Kumamoto Prefectures, a linear rainband may form in the next few hours, and in Shimane and Tottori Prefectures, it may form from now until evening, sharply increasing the risk of disasters. Strict caution is required.

According to the Japan Meteorological Agency, moist air is flowing toward the stationary autumn rain front, making the atmosphere extremely unstable and causing rain clouds to develop in areas such as Kyushu and the Chugoku region.

A linear rainband has formed in the southern part of Nagasaki Prefecture and the Amakusa/Ashikita regions of Kumamoto Prefecture, causing extremely heavy rain to continue falling in the same areas. As a result, significant heavy rain information has been issued.

In the one hour up to 6 a.m., an extremely heavy rainfall of 122 millimeters was observed by a rain gauge installed by Kumamoto Prefecture in Reihoku Town.

In addition, during the one hour leading up to 8 a.m., 66 millimeters of rain was recorded by a rain gauge installed by Kumamoto Prefecture in Kami-Amakusa City, and 52 millimeters was recorded by a rain gauge installed by Hiroshima Prefecture in Saka Town, indicating that extremely heavy rain has been observed not only in Kyushu but also in the Chugoku region.

In Minamishimabara City, Nagasaki Prefecture, in just six hours until 8 a.m., they received an amount of rain equivalent to what they usually get in the entire month of September.

5 millimeters of rain fell, which is the highest amount since statistics began being recorded.

Due to the recent rain, the risk of landslides has become extremely high in Nagasaki and Kumamoto prefectures, and landslide warning information has been issued for certain areas.

The outlook: As the front slowly moves southward, atmospheric conditions will become unstable, mainly on the Sea of Japan side but also on the Pacific side. From northern to western Japan, heavy rain accompanied by thunder is expected, and there is a risk of extremely heavy localized rainfall.

▽In Nagasaki and Kumamoto prefectures, where torrential rain is falling, heavy rain is expected to continue for the next few hours. ▽In Shimane and Tottori prefectures, a linear rainband may form from now until the evening, rapidly increasing the risk of disasters.

The amount of rainfall expected in the 24 hours leading up to the morning of the 11th is, at most, 180 millimeters in northern Kyushu, 150 millimeters in the Chugoku region, and 100 millimeters in the Kanto-Koshinetsu and Hokuriku regions. If a linear rainband forms, rainfall could increase even further.

The Japan Meteorological Agency is urging people to be extremely cautious of landslides, as well as to watch out for flooding in low-lying areas and rising or overflowing rivers.

Be careful of severe gusts such as lightning and tornadoes, as well as hail.
