Early Preparedness for Typhoon in Okinawa

Typhoon No. 14 is expected to follow the path of Typhoon No. 13, moving northwest near Japan and passing close to Okinawa on Wednesday, the 18th, heading towards the East China Sea.

No significant development is anticipated, and it is forecasted that the storm area will not accompany its peak, but there is a risk of strong winds, high waves, and heavy rain for Okinawa and Amami, which are close to its path. Therefore, please pay attention to future path information. It is advisable to prepare for the typhoon early for peace of mind.

Additionally, the classification of “large” indicates a wide diameter of the storm area and does not relate to intensity.

Reference: Numerical simulation results computed by meteorological agencies worldwide

The thin lines in this diagram represent the results of numerical simulations calculated by meteorological agencies from around the world. They are part of an ensemble forecast method, displayed to visualize the considerable range of expected paths.

Comparing these members shows that while there is a general tendency for them to head north off the east coast of Japan, there is variation in the predictions that diverge to the northeast beyond that point or head toward Honshu. If the path is more westward, there is a potential for wind and rain impacts around the long weekend, so careful monitoring of forecast changes is essential. The error is expected to diminish as time progresses, so please stay tuned for future information.

Probability of Entering the Typhoon’s Storm Area

For the forecast areas where the probability of entering the typhoon’s storm area within the next five days is over 3%, they are as follows. (Japan Meteorological Agency)
　Amami Region　　　2 %
　Okinawa Main Island Region　13 %
　Miyako Island Region　　54 %
　Yaeyama Region　　72 %

New Typhoon is Expected to Form

Moreover, the Japan Meteorological Agency announced at 9 AM today, September 16 (Monday), regarding the tropical depression east of the Philippines, that “it is expected to develop into a typhoon within the next 24 hours.”

If it becomes a typhoon, it will be referred to as “Typhoon No. 15.”

This tropical depression is anticipated to move westward towards the South China Sea, so it is not expected to directly impact Japan.
