It has already rained heavily in Kyushu, so please be extremely vigilant against landslides, flooding of low-lying land, and flooding of rivers.
Risk of occurrence of “linear rain belt” in southern Kyushu
There is a seasonal rain front in the vicinity of Kyushu, and this front is expected to slowly move southwards in northern Kyushu on the 3rd and remain stagnant in the southern part of Kyushu on the 4th.
As “warm and moist air” that causes heavy rain flows toward the Baiu front, the atmospheric conditions will be very unstable in the northern part of Kyushu on the 3rd and in the southern part of Kyushu on the 4th.
In particular, in the southern part of Kyushu, a “linear rain belt” will occur from the afternoon of the 3rd to the morning of the 4th, and the risk of heavy rain disasters may increase sharply.
What is the expected rainfall?
In Kyushu, the risk of landslide disasters is already very high due to heavy rains. According to the Japan Meteorological Agency’s “Kikikuru”, the risk of landslide disasters is increasing over a wide area, mainly in northern Kyushu.
In addition, heavy rain with thunder and very heavy rain will fall in Kyushu through the morning of the 4th.
[Predicted rainfall for 24 hours until 12:00 on the 4th (heavy places)]
Southern Kyushu 300mm
Northern Kyushu 200mm
[After that, the amount of rain expected for the next 24 hours until 12:00 on the 5th (heavy places)]
Northern Kyushu 100 to 200 mm
Southern Kyushu 100 to 150 mm
Amami region 100 to 150 mm
In addition, if a linear rain belt occurs, there is a possibility that the amount of rain will increase locally. In Kyushu, on the 3rd, please be on high alert for landslides, flooding of low-lying land, rising water levels and flooding of rivers.
In addition, thunder clouds will develop locally, so be careful of strong gusts such as lightning strikes and tornadoes in northern Kyushu on the 3rd and southern Kyushu on the 4th.
If a “linear rain belt” is predicted to occur
If the Japan Meteorological Agency announces information calling for the possibility of torrential rain due to a “linear rain belt” in about half a day’s time, somewhere in the area targeted for the announcement, it will rain torrential rain or very heavy rain, The risk of heavy rain disasters may increase sharply. Please take the following actions.
① Please be aware that the possibility of heavy rain disasters is higher than usual, and watch the weather information frequently on your TV or smartphone.
② If you live near a river or in an area where there is a risk of landslides, consider that you may evacuate, and pay attention to evacuation information announced by local governments. At this stage, reconfirm what you need to bring to the shelter, such as food, drink, valuables, and a change of clothes, and prepare to evacuate immediately if necessary. Evacuation after dark is dangerous. Make sure to evacuate while it is still light while checking weather information and evacuation information frequently.
③ In addition to the evacuation shelters designated by the local government, it is a good idea to consider multiple options, such as the safe homes of relatives and acquaintances, hotels, and inns. As a countermeasure against infectious diseases, please prepare disinfectants and masks. Even if you are worried about infection, measures against infectious diseases are progressing at evacuation centers, so if you can’t think of another evacuation destination, don’t hesitate to evacuate.
Atmospheric conditions are extremely unstable not only in Kyushu, but also in a wide area from western to eastern Japan.
On the 3rd, strong cold air with a temperature of minus 9 degrees Celsius or below is expected to flow into the sky about 6000 meters above Honshu. Furthermore, the weather will become very unstable from western Japan to eastern Japan due to sunny weather and rising temperatures during the day.
Not only in Kyushu, but also in a wide area from western Japan to eastern Japan, there is a risk of guerrilla downpours (short-term heavy rains) even if it is sunny, so be careful of strong gusts such as lightning strikes and tornadoes.
If there are signs of an approaching cumulonimbus cloud, please take measures to ensure safety, such as moving inside a building. Hail is also expected, so please pay attention to the management of crops and agricultural facilities.
