The rainy season front will move southward through tomorrow, a dangerous pattern, and heavy rain peaks at night
June 30, 2023 07:53
From today 30th (Friday) to tomorrow 1st (Saturday), the rainy season front will move south from Kyushu to the vicinity of Honshu. This is a very dangerous weather map pattern where disaster-level heavy rain is expected. In some places, heavy rain peaks at night, so try to evacuate early while it is still bright.
The seasonal rain front becomes active and moves southward tomorrow, bringing heavy rain
Today, the 30th (Friday), warm and moist air is flowing toward the seasonal rain front that extends to the Sea of Japan, and the atmospheric conditions are extremely unstable over a wide area.
As of 7:30 a.m., rain clouds have developed in places from Kyushu to Hokuriku and Tokai, and there are areas in Kyushu where the risk of landslide disasters is high due to the heavy rain that has already fallen.
The rainy season front will slowly move southward from Kyushu to the vicinity of Honshu from tomorrow (Saturday). It is a very dangerous pattern that is often seen from the peak to the end of the rainy season, and is expected to bring disaster-level heavy rain.
Evacuate early even in places where heavy rain peaks at night
Kyushu is already experiencing intermittent heavy rain, and although “very heavy rain” has been observed in some places, active rain clouds will continue. After this evening, the area where “very heavy rain” will fall is likely to spread further. The most vigilant hours are from evening to early morning, when the sky is dark. Evacuation may become difficult due to the sudden change in surroundings while you are asleep. Please check the information and weather information announced by the local government frequently, and try to evacuate early while it is still light.
In the Chugoku region, there are many places where the rain has weakened, but we cannot let our guard down. More rain is expected tonight through tomorrow morning. It is also possible that heavy rain will fall at night and the water level of the river will suddenly increase.
Shikoku is likely to see a peak rainfall from early morning to early afternoon, and Kinki is likely to hit its peak from early morning today to early afternoon tomorrow. Heavy rain is expected in Hokuriku before noon, and it will rain very heavily locally. Heavy rain accompanied by thunder is expected in the Tokai area through the evening and in the Tohoku area through the early hours of tomorrow.
Depending on the movement of the seasonal rain front, the time and place where the rain will intensify may change. Please check back frequently for the latest information.
When evacuating by driving a car in heavy rain, be careful
Even if you drive to an evacuation center in heavy rain, you can’t let your guard down. There are two caveats.
The first is to drive more cautiously than usual when it rains heavily. If it rains more than 20mm in an hour, it will be difficult to see even if the wipers are fastened. In addition, if it rains more than 30mm in an hour, there is a risk of “hydroplaning”, where the brakes do not work at high speeds, so you need to be careful. “Extremely heavy rain” of 50 mm or more per hour impairs visibility and makes driving dangerous.
The second is to choose the route to the evacuation site. Heavy rains can cause rivers to swell and roads to be submerged. Choose a route as far away from the river as possible. If the car is submerged in water, the door may not open and you may be trapped inside the car or the car engine may stop. In addition, if the water gets deeper or the current gets faster, the whole car may be swept away. Roads flooded by heavy rain make it difficult to see the boundary between rivers and rivers.
