OVERVIEW OF THE WESTERN PACIFIC BASIN:

Western North Pacific More tropical cyclones form in the tropical North Pacific than anywhere else in the world. More than 25 (tropical storms and typhoons) develop each year, and about 18 become typhoons. These typhoons are the largest and most intense in the world. Each year an average of five generated maximum winds over 130 knots (150 mph); circulations covering more than 600 miles in diameter are not uncommon. Most of storms form east of the Phillippines, and move across the Pacific towards the Phillippines, Japan, and China; a few storms form in the South China Sea. The season extends from April through December. However, tropical cyclones are more common in off-season months in this area than anywhere else. The peak of the season is July through October, when nearly 70 % of all typhoons develop. There is a noticeable season shift in storm tracks in this region. From July through September, storms move north of the Philippines and recurve, while early and last-season typhoons move on a more westernly track through the Phillippines before recurving.
