Pacific high pressure system guides Tropical Depression TD09 west for next five days

A powerful Pacific high-pressure system, stretching thousands of kilometers from the central Pacific to the northern South China Sea, is currently dictating the movement of Tropical Depression TD09. Weather forecasters indicate that TD09 will continue its stable westward trajectory along the southern periphery of this extensive high-pressure ridge for the next five days.

The weather fan page "Taiwan Typhoon Forum | Weather Express" shared satellite imagery showing the vast expanse of the Pacific high-pressure system, highlighting areas with no clouds as its domain. This strong system is guiding TD09.

Forecasters anticipate that TD09's path could become more variable once it nears the waters south of Japan's Ryukyu Islands. At this point, the Pacific high-pressure system is projected to gradually weaken, consequently altering the steering currents that influence the typhoon's direction. The evolution of the high-pressure system in the coming week is considered the most critical factor to monitor.

Meanwhile, Tropical Depression TD10 is also developing, with the Meteorological Administration predicting that both systems have the potential to intensify into light typhoons.
