1955 Pacific typhoon season

The 1955 Pacific typhoon season has no official bounds; it ran year-round in 1955, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1955 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Fleet Weather Center on Guam.

The rest of the storms, such as unnumbered and unnamed tropical depressions and storms, are only classified by the CMA while the JMA is sometimes rare before the 1960s - 1970s.

Anita encountered on a phase of cool waters, and as a result, it gradually weakened. Anita but re-intensified into a category 1 typhoon on April 20. However, it weakened again on April 22 but again re-intensified to a category 1 and even a category 2 typhoon later. Anita reached its peak intensity as a category 3 typhoon.

Intensification occurred and Fran intensified from a category 1 to 4 typhoon and reached its peak intensity. After peaking in intensity, unfavorable environments made Fran to start a weakening trend. On July 20, Fran weakened to a category 2 typhoon and later weakened to a category 1 typhoon and even as a strong tropical storm. On July 21 of noon, Fran weakened to a tropical depression, and soon encountered with strong wind shear and dissipated.

Louise formed on September 20 as a weak tropical depression. It intensified into a tropical storm and even a typhoon later.
