長崎ながさき県けん 線状せんじょう降水こうすい帯たい発生はっせいの恐おそれ 九州きゅうしゅう北部ほくぶ・北陸ほくりくなど厳重げんじゅう警戒けいかいを

Due to the influence of a front, record-breaking heavy rain has occurred mainly in Kumamoto Prefecture, and rain clouds are developing mainly over the Sea of Japan, causing extremely heavy rain in Oki, Shimane Prefecture.

In Nagasaki Prefecture, there is a risk of a linear rainband forming in the next few hours, and in areas such as northern Kyushu, which has experienced record-breaking heavy rain, as well as in Hokuriku and other regions, the danger of disasters remains high. Please continue to be extremely vigilant against landslides.

According to the Japan Meteorological Agency, the activity of the front became extremely intense on the 11th, and a series of linear rainbands formed in Kumamoto and Nagasaki prefectures. The agency issued a special heavy rain warning for areas such as Tamana City and Nagasu Town in Kumamoto Prefecture.

5 millimeters, both of which are the highest since statistics began being recorded, reached about twice the average amount for the entire month of August in just half a day.

The front is moving north over the Sea of Japan, and at this time, in addition to Oki in Shimane Prefecture, the rain is also intensifying in Nagasaki Prefecture, Yamaguchi Prefecture, and other areas.

In Oki, an extremely heavy rain of 60 millimeters fell in one hour until 6 a.m., as measured by a rain gauge installed in Nishinoshima Town.

In Fukuoka, Yamaguchi, Ishikawa, and Niigata prefectures, there are areas where a Landslide Warning Information has been issued due to a significantly increased risk of landslides.

There are rivers in Kumamoto, Yamaguchi, and Ishikawa prefectures that have exceeded the flood danger level.

The front is expected to remain stationary from the Sea of Japan side of western Japan to the Tohoku region through the 13th, so unstable atmospheric conditions will persist, mainly along the Sea of Japan side from western to northern Japan, with intermittent periods of heavy rain expected.

There will be places where heavy rain or very heavy rain accompanied by lightning will fall, resulting in torrential downpours. Especially in Nagasaki Prefecture, there is a possibility that a linear rainband will form in the next few hours, causing the risk of disasters to increase rapidly.

In addition to northern Kyushu, which experienced record-breaking heavy rain, the risk of disasters has increased in various regions such as the Chugoku and Hokuriku areas.

Especially in Kyushu, there are areas where the ground has loosened and river embankments or revetments have been damaged, so even a small amount of rain could increase the risk of disasters such as landslides or river flooding.

The Japan Meteorological Agency continues to urge strict caution against landslides, as well as vigilance for flooding in low-lying areas and rising river levels. They are also warning to watch out for lightning, tornadoes, other severe gusts of wind, and hail.

《Points to Note When Evacuating》When evacuation information is announced by local authorities, it is important to evacuate to a safe place. However, forcing yourself to move may actually be dangerous in some cases.

Here are some important points to keep in mind when evacuating.

[If the road is flooded] If the road is flooded, you may not be able to see your footing and could fall, or there is a risk of falling into a ditch or an open manhole.

Please avoid traveling on flooded roads.

When the water level rises above knee height, the force of the flowing water becomes stronger, making it difficult to escape on foot.

There are also dangers when traveling by car.

If the water depth reaches 30 centimeters, the engine will stop, and if the water gets even deeper, it will become difficult to open the doors, and the entire car may be swept away.

If your car starts to flood, get out immediately.

There is a risk that rivers and irrigation channels may already have overflowed, making it difficult to distinguish them from the road, or that you may not notice roads that have collapsed due to floodwaters.

Please avoid passing near rivers or waterways.

If a levee breaks and flooding occurs in a large river, a huge amount of water will rush out all at once, which can sweep away houses and poses a risk of widespread and prolonged inundation.

When the risk of flooding increases in large rivers, the national or prefectural governments that manage the rivers jointly issue Flood Risk Information in cooperation with the meteorological observatory.

When this information is released, it is important to pay attention to information from local authorities and evacuate early.

Also, you need to pay attention not only to the rainfall in your own area, but also to the rainfall and water levels upstream of the river.

[Precautions for Landslides] When the risk of landslides becomes extremely high, the Meteorological Observatory and the prefectural government jointly issue a Landslide Warning Information.

If you are in an area at risk of landslides, please pay attention to information from your local authorities and evacuate early.

It is not always guaranteed that information will be announced before a landslide occurs.

If you notice any unusual phenomena, immediately move away from cliffs or slopes and ensure your safety.

It is also important to note that there is not always a warning sign.

[It may already be dangerous to move] When you try to evacuate, you may not be able to check the situation around you due to rain, or landslides and other disasters may have occurred, making it already dangerous to move.

One option in such cases is to move to a room on the second floor or higher of a building, or to a room away from cliffs and slopes.

Please move to a safer place, even if only a little, and ensure your safety.

In each prefecture of Kyushu, heatstroke alerts have been issued, so please make sure to take sufficient precautions such as taking frequent breaks when cleaning up or carrying out recovery work, and check in with those around you to see if anyone is feeling unwell.
