Typhoon number 9 (Mei Sark) will be closer to Okinawa on the night of Monday the 31st tomorrow.

Usually, the area of ​​the sea with a high sea surface temperature is limited to the extreme south sea of ​​Japan, but this year, the area of ​​the sea with a high sea surface temperature extends considerably to the north , and the sea surface temperature exceeds 28 degrees Celsius even in the waters near Japan. In a typhoon-prone environment, Typhoon 9 can develop further from “very strong” forces.

Typhoon No. 9 approaches Okinawa with a region of storms from the night of 31 (Monday) to the morning of September 1 (Tuesday) while maintaining a very strong influence. The central air pressure is predicted to be 935-945 hPa, the maximum wind speed near the center will be 45-50 m / s, and the maximum instantaneous wind speed will be 65-70 m / s at sunrise ( Tuesday), which is expected to be the closest. I will.

If forces approach as predicted, there are fears that even in Okinawa, which is relatively used to typhoons, there will be large-scale typhoon damage.

Typhoon No. 15, which passed in August 2015, has a central pressure of 935 hPa and a maximum wind speed of 50 m / s at the time of closest approach. Ishigaki Island recorded the highest instantaneous wind speed of 71.0 m / s, which was the first in the history of the observation, and it was in a situation where the parked car rolled over and the traffic light collapsed along with the struts.

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. Complete typhoon countermeasures before the morning of Monday morning 31st.

Typhoon 9 will pass near Okinawa early in the week and head to the East China Sea. After that, the course will most likely change to the northeast and continue north to Kyushu, and it may pass near western Japan, like Kyushu.

Since the forecast circle is relatively small over the next three days, it can be said that the width of the possible course is narrow, that is, the certainty of the expected 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.
