Typhoon No. 11 threatens storms in Sakishima Islands

As of 6:00 on September 1 (Friday), Typhoon No. 11 (Haikui) is moving west-northwest south of Okinawa. The central pressure is 985hPa, and the maximum wind speed near the center is 30m/s. It is expected to develop somewhat in the future and become a “strong” force.

From tomorrow 2nd (Sat) to 3rd (Sun), we will be closest to the Sakishima Islands in Okinawa. Storm winds of around 40m/s are expected to blow in the Sakishima Islands, and there is a risk of rough weather, so please prepare today.

In addition, since the pressure difference between Typhoon No. 11 and the Pacific High, which is spreading near Honshu, is increasing, a strong wind area is spreading to the north of the typhoon. In the main island of Okinawa and the Amami region of Kagoshima Prefecture, the wind will intensify from today (Friday), so please be careful of strong winds and high waves. Heavy rains with moist air are also expected. Even if you are far from the center of the typhoon, you should not let your guard down.
