A lull in tropical cyclone activity across the Western Pacific has come to an end early in September and another cyclone may form later this week.
Tropical Storm Fengshen (13W) missed mainland Japan early this week as it turned northeastward and raced into the open Pacific. To the south, Tropical Depression 14W brought heavy rain to southeastern China.
In the wake of these two cyclones, attention turns to an area of disturbed weather near Guam and the Northern Mariana Islands. This area of thunderstorms is in a favorable area for development and organization is possible through the end of the week.
A combination of low wind shear and warm water temperatures in the region make it conducive for development.
A sluggish westward track is expected, and the disturbance could strengthen into a tropical storm towards the end of the week or during the weekend.
By the end of the weekend or start of next week, signs point to the disturbance approaching the Philippines.
AccuWeather.com Senior Meteorologist Jason Nicholls explained, "The slow movement of this disturbance could bring persistent rounds of heavy rain to the Philippines. There could also be gusty winds although rain is the main concern."
If this system were to become an organized tropical cyclone, it would most likely stay south of Japan. Anyone with interests from the Philippines to Taiwan should continue to monitor the situation through the week.
