The main island of Okinawa is on strict alert for landslides throughout the night
rain cloud radar
A little away from the center of the typhoon, there is a band of active rain clouds called a spiral band, and the typhoon moves slowly, so it continues to cover the main island of Okinawa. More than 250 mm of rain fell in 24 hours in Motobu Town, and the total amount of rain reached 700 mm.Due to the large amount of rain, the risk of landslide disasters is extremely high throughout the main island. Heavy rain is expected to continue into tonight, and the dangerous situation will continue for some time after the rain subsides. In preparation for the occurrence of a sediment disaster tonight, it is necessary to ensure safety by evacuating in advance.
Although the wind will gradually subside, high waves will continue on the sea, so please stay away from the sea for the rest of the day.

Risk of heavy rain exceeding 500mm mainly in Kyushu
Predicted cumulative rainfall by the morning of the 10th (Thursday)
The Pacific side of western Japan was affected by the southerly moist winds that blew in front of the typhoon, causing locally active rain clouds. The rain is still not that strong, with around 10mm per hour, but it is expected to get stronger as the typhoon approaches.Since the typhoon will change its course to the north from now on, the wet air will continue to flow into western Japan until Thursday, the 10th, when the typhoon passes into the Sea of Japan.
As a result, the amount of rainfall will increase, and according to Weathernews’ own forecast, the amount of rainfall will exceed 500mm in areas with heavy rainfall in Kyushu by the morning of Thursday the 10th. The risk of disasters due to heavy rain increases, so 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.
There is uncertainty about the timing and course of approaching Japan
Reference Results of simulations of paths calculated by meteorological agencies around the world
Each thin line in this figure represents the simulation result of the course calculated by meteorological agencies around the world. The results (members) obtained in the process of the ensemble forecast method are posted to give an image of the wide range of possible paths.
Comparing these members, we can see that the tendency to move north after moving east toward the Amami area is generally the same, but there are large variations in the timing and position of moving north. The impact on each region will change depending on your course, so please pay attention to future information.
Watch out for high waves on the Pacific side of western Japan and eastern Japan
Forecast of waves on the morning of the 8th (Tue)
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.According to the forecast for the morning of the day after tomorrow, the 8th (Tuesday), the waves are expected to reach around 5m along the coasts of Kyushu and Shikoku, and around 2m even in areas away from the typhoon, 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.
