While former Typhoon Kalmaegi is still bringing flooding rains and the potential for mudslides to northern Indochina and southern China, another threat is already brewing east of the Philippines.
An area of showers and thunderstorms several hundred miles east of the Philippines has become better organized in the past 24 hours and developed into Tropical Depression 16W.
This depression will track toward the northwest over the next 24-48 hours, taking the storm just east of Luzon.
While the storm may never make landfall in the Philippines, it will likely pass close enough to bring gusty winds and heavy rainfall to Luzon, including areas that were hit with flooding less than a week ago by former Typhoon Kalmaegi.
Strengthening is expected over the next 72 hours, and this tropical system will likely be at least a tropical storm as it passes the Philippines and continues northwest toward Taiwan.
Interaction with a trough moving into eastern China will be the key factor in the movement of this tropical system. As the system interacts with this trough, a turn to the north is expected.
At this time, it seems most likely that the center of the tropical system will pass east of Taiwan; however, the island could still be lashed by damaging winds and flooding rainfall.
Strengthening is expected through the weekend as the storm will likely turn northeastward impacting the Ryukyu Islands of Japan before a potential landfall in southern or eastern Japan early next week.
This tropical system has the potential to become a powerful typhoon which could bring widespread damaging winds, flooding and mudslides to areas in its path.
Areas from the northern Philippines through Taiwan and Japan could closely monitor this tropical system over the coming days.
