These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
The season produced a large number of tropical storms but most of them were weak, and sources from American typhoon warning agencies often grossly overestimated the maximum wind speed of many systems which could not properly match with their respective central pressure observations.
The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line.
Tropical Storms formed in the entire west Pacific basin were assigned a name by the Fleet Weather Center on Guam.
Forming in an area full of islands, Wilda moved up into the open ocean where it reached typhoon strength.
Soon enough, Wilda had weakened under typhoon strength and dissipated on March 29.Anita formed as a tropical depression on April 17.
It entered a phase of favorable environments and was soon upgraded into a tropical storm and named Fran.
On July 21 of noon, Fran weakened to a tropical depression, and soon encountered with strong wind shear and dissipated.
Wind shear quickly decreased and sea surface temperatures began to rise and Louise rapidly intensified into a category 5 super typhoon.
Patsy reached its peak intensity before undergoing an eyewall replacement cycle and started to weaken.
