Moving west and distancing from Japan

Typhoon No. 11 is expected to slowly develop and reach strong powers by Thursday, September 5. After moving north over the sea east of the Philippines, it will change its course to the west following Tuesday, September 3, heading towards the South China Sea and the Chinese mainland. Since it will be moving away from the Japanese archipelago, direct impacts are considered minimal.

Reference: Numerical simulation results of the course calculated by meteorological agencies around the world.

This figure shows the results of numerical simulations calculated by meteorological agencies worldwide, represented by each thin line. It is published to convey the range of possible routes obtained through the method of ensemble forecasting (members).
Comparing these members, while there is a general tendency to move north off the east of Japan, there is variation in forecasting between turning northeast after that and heading towards Honshu. If the course is to the west, there may be rain and wind impacts around the three-day weekend, so it’s necessary to pay attention to forecast changes. As time goes on, the errors are expected to decrease, so please keep an eye on future information.
