As of 15:00 on Thursday, August 31, three typhoons, Typhoon No. 9 (Saora), Typhoon No. 11 (Haikui), and Typhoon No. 12 (Kirogi), have occurred.
Typhoon No. 11 will change its course to the south, and it is expected to approach Okinawa and the Sakishima Islands the day after tomorrow, September 2nd (Saturday). However, there is no change in the situation where the wind and rain are likely to intensify on the north side of the typhoon, so it is necessary to be vigilant against high waves and pay close attention to strong winds in the Okinawa and Amami regions.
Typhoon No. 12 is expected to move north to the south of Japan over the weekend.

Typhoon No. 11 threatens storms in Sakishima Islands
As of 15:00 on Thursday, August 31, Typhoon No. 11 (Haikui) is moving west-northwest in the waters near Okinotorishima. The central pressure is 985hPa, and the maximum wind speed near the center is 30m/s. It is expected to develop further in the future and become a “strong” force by tomorrow.
Its course is gradually moving southward, and it is expected to pass near the Sakishima Islands around Saturday, the 2nd with a strong wind area. The Sakishima Islands require strict vigilance against storms, heavy rain, high waves and high tides accompanied by swells.
In addition, since the pressure difference between Typhoon No. 11 and the Pacific High, which is spreading near Honshu, will increase, a strong wind area is expected to expand to the north of the typhoon. There is no change in the view that the wind will strengthen in the main island of Okinawa and the Amami region, so please be vigilant against high waves and be careful of strong winds.
Active rain clouds outside the typhoon, called the outer band, and heavy rain due to moist air are also expected. Even if you are far from the center of the typhoon, you should not let your guard down.

Typhoon No. 12 is expected to turn into a tropical cyclone in the south of Japan
As of 15:00 on Thursday, August 31, Typhoon No. 12 (Kirogee) is moving north in the sea near Minamitorishima. It developed slightly from the morning, with a central pressure of 992hPa and a maximum wind speed of 25m/s near the center. After this, it is expected to move northwest as if to go around the Pacific high, and after making the closest approach to the Ogasawara Islands around Saturday, September 2, it will approach the sea south of Honshu.
It is expected to temporarily become a force with a storm area, but after that it weakens and loses strength, and it is expected to turn into a tropical cyclone south of Japan on the 3rd (Sunday).
Although the possibility of stormy weather due to the typhoon itself is low, this course will carry moist air into the Japanese archipelago, so even if it becomes a tropical cyclone, there is a risk of heavy rain. Stay tuned for future information.

The average number of typhoons in August is 5.7, which is the time of the year with the most typhoons. The number of typhoons this year is slightly lower than usual, but Weathernews forecasts that there will be at least 10 more typhoons by the end of the year.
As autumn approaches, it is expected that the number of typhoons that affect the Honshu area will increase, so please prepare for typhoons and heavy rains in preparation for the coming season.
