Heavy rain on the Pacific side of western Japan
Active rain clouds continue to hover over similar areas due to the continued moist air flowing into the Pacific Ocean side of western Japan.
The typhoon will continue to slow down after this, and is expected to pass over the west coast of Kyushu at a speed of 10 to 20 km/h tomorrow, Wednesday, the 9th.
Since very warm and moist air blowing from the east side of the typhoon continues to flow in, it is expected that rain clouds that have developed in similar areas will be more likely to cover the area after this as well.

Developed rain cloud band extends to southern Kyushu
State of rain clouds 8th (Tue) 20:45
Kagoshima Prefecture was already covered by a band of active rain clouds called a “spiral band” surrounding the typhoon, and heavy rainfall of 27.5 mm was observed in Tashiro and 24.5 mm in Sata in one hour until 20:20.In the future, as the typhoon moves northward, the spiral band is expected to reach Miyazaki prefecture. Rain clouds develop especially in areas where moist winds from the southeast hit the mountains, and there is a risk of heavy rainfall.
In some cases, a linear rain belt may be formed, increasing the risk of heavy rain disasters. Western Japan needs to be careful of heavy rain until the 10th (Thursday) when the typhoon leaves.
Due to the slow speed of the typhoon, there is concern that heavy rain will last longer. The total amount of rainfall will increase, and it is expected that there will be new places with more than 300mm of rainfall in the Pacific side of Kyushu and Shikoku, and the southern part of the Kii Peninsula.
Heavy rains are expected to hit areas that are already experiencing heavy rains, increasing the risk of disasters. If it is difficult to move to an evacuation center at night, do not overdo it, and try to evacuate to the second floor or higher of your house to ensure your safety.
Even in Tokai and Kanto, which are far from the typhoon, it is necessary to pay attention to the possibility of temporary intensification of rain due to the influx of moist air.
In addition, there is a risk of heavy rain of around 500 mm
Predicted cumulative precipitation until the afternoon of Thursday, October 10
After this, the Pacific side of Kyushu and Shikoku, and the southern part of the Kii Peninsula are expected to experience particularly heavy rainfall. According to Weathernews’ own forecast, by the morning of the 11th (Friday) after the passage of the typhoon, it is expected that there will be more than 300mm of rain in some places. Heavy rains are expected to hit areas that are already experiencing heavy rains, increasing the risk of disasters. Please prepare for heavy rain early.Even in Tokai and Kanto, which are far from the typhoon, it is necessary to pay attention to the possibility of temporary intensification of rain due to the influx of moist air.
In addition, Kyushu, which is close to typhoons, will have stronger winds tomorrow. The maximum instantaneous wind speed can reach nearly 40m/s, so be prepared for storms by putting away anything that can fly easily today, reinforcing the window glass, etc.
Beware of storms and high waves
Kyushu, which is close to typhoons, will have stronger winds tomorrow. The maximum instantaneous wind speed can reach nearly 40m/s, so be prepared by removing things that can easily fly away early and reinforcing the window glass.
Typhoon No. 6 is accompanied by a wide area of strong winds, and the pressure difference between it and the Pacific high that extends from the east strengthens the southerly winds, resulting in high waves over a wide area on the Pacific side.
On the East China Sea side and the Pacific Ocean side of Kyushu where the typhoon is approaching, a heavy storm of around 8m is expected until tomorrow, Wednesday, the 9th. It is expected to reach around 5m on the coast of Shikoku, and around 3m in areas away from typhoons such as Tokai and Kanto.
Please refrain from leisure activities in the sea as much as possible, and follow the instructions when swimming is prohibited, such as at a beach.
