Typhoon No. 9 (Meisak) is approaching the main island of Okinawa at an instantaneous maximum wind speed of 70 m / s or be alert for a disaster-like weather report

A marine area with a sea surface temperature of 28 ° C or more extends over the southern seas of Honshu, creating an environment where typhoons are likely to develop.

Typhoon No. 9 develops rapidly from 30 (Sunday) to 31 (Monday), and is expected to become a “very strong” force at 9:00 on the 31st, when it is considered to be the closest time. to the main island region of Okinawa. As you approach, the central pressure is 925 hPa, the maximum wind speed near the center is 50 m / s, and the instantaneous maximum wind speed is predicted to reach 70 m / s.

If the forces approach as predicted, there are fears that even Okinawa, which is relatively used to typhoons, will suffer damage from large-scale typhoons. The impact of heavy rains was the main factor when it approached Typhoon No. 8 last time, but Typhoon No. 9 is expected to be affected by storms, high waves and high tides in addition to heavy rains, so it is required strict caution.

Typhoon 9 is expected to continue into the East China Sea after passing through the Okinawa region. After that, the course will most likely change to the northeast and continue towards the Korean peninsula, and it may pass near Kyushu.

Since the forecast circle is relatively small for the next four days, it can be said that the width of the possible course is narrow, that is, the certainty of the predicted course is relatively high. There is no relationship between the size of the forecast circle and the size of the typhoon, so even if the forecast circle is small, be careful and take appropriate action.

Typhoon No. 9 is the seventh typhoon that started in August this year. The average number of typhoons generated in August is 5.9, so it can be said that the rate is slightly higher than in normal years.

Typhoons approaching Honshu may increase in the fall. Recheck for heavy rain and storms caused by typhoons.
