» Latest typhoon information
Firstly, there is a risk of impact on Okinawa from the middle of the week.
Typhoon No. 21, which occurred in the Mariana Islands, is moving rapidly west and has not developed much at the moment. From now on, it is expected to gradually slow down and become stronger, and strong winds are expected to develop by the beginning of next week.From around the 30th (Wednesday), there is a chance that it will change course to the north and move towards Okinawa/Amami. As a “strong typhoon” is expected to enter the area, there is a risk of heavy rain and strong storms. Please take typhoon measures soon.

There is also a chance that the Honshu area will be affected in the second half of the week.
Reference Numerical simulation results of the course calculated by meteorological agencies around the world
The Japan Meteorological Agency’s typhoon information predicts the path of the typhoon up to five days in advance, but if we consider the subsequent forecast using numerical simulations, we can consider the possibility of affecting the Honshu region.Each thin line in this diagram represents the results of numerical simulations calculated by meteorological organizations around the world. These are the calculated results for the center of the cyclone using a method called ensemble forecasting, and can be used to examine the reliability of forecasts by deliberately adding errors to the initial values.
In comparison, it can be seen that although the trend of movement westward to the south of Okinawa is generally the same, there are variations in the subsequent course. Most current forecasts predict a course that will move southeast of Honshu, but some calculations predict a course that will move southwest of Taiwan.
The error is expected to decrease as the days go by, so keep an eye out for future information.

There is a chance that the front near Honshu will become active.
The autumn rain front is expected to remain stationary near Honshu before Typhoon No.By the time the typhoon reaches southern Okinawa on the 30th (Wednesday), the front is expected to extend to the southern coast of Honshu, bringing in moist air from the southeast and causing rain clouds to form. If the typhoon then moves north, there is a risk that the typhoon and the clouds from the front will merge, causing heavy rain over a wide area. Please note that the impact will vary greatly depending on the path of the typhoon.

Probability of entering a typhoon storm area
The following are the prefectural forecast areas where the probability of entering the typhoon storm region within the next 5 days is 3% or higher. (Japan Meteorological Agency)
Okinawa main island region
North and south center of main island 5%
Kerama/Aguni Islands 8%
Kumejima 11%
Miyakojima Region 32%
Yaeyama region
Ishigaki Island area 45%
Yonagunijima Region 47%
Honshu rarely comes to November.
Number of typhoons in a typical year
The average number of typhoons is 3.4 in October and 2.2 in November, so it can be said that there are still typhoons even in normal years. On the other hand, the number of typhoons approaching Japan decreased significantly in November, with only three typhoons approaching the mainland (Hokkaido, Honshu, Shikoku, and Kyushu) since 1951.However, there is a case where Typhoon No. 28 of 1990 will land on Honshu at the end of November, so we must not let our guard down just yet. If Typhoon No. 21 to land in Japan, it would be the second latest landing in statistical history.

name of a typhoon
Regarding the names of typhoons found in the Northwest Pacific Ocean or the South China Sea, 140 names were prepared in advance, recommended by the member countries of the international organization “Typhoon Commission”, and are given in the order they occur.Cambodia suggested the name “Kong-rey” for Typhoon No.
