Pacific typhoon seasons
1966, 1967, 1968, 1969, 1970

The 1968 Pacific typhoon season has no official bounds; it ran year-round in 1968, 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 1968 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Weather Bureau, the predecessor of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). This can often result in the same storm having two names.

Systems

[edit]

31 tropical depressions formed this year in the Western Pacific, of which 27 became tropical storms. 20 storms reached typhoon intensity, of which 4 reached super typhoon strength. No storms this season caused significant damage or deaths.

The Philippine Weather Bureau (later renamed to the Philippine Atmospheric, Geophysical and Astronomical Services Administration in 1972) uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 6 of which are published each year before the season starts. Names not retired from this list will be used again in the 1972 season. This is the same list used for the 1964 season, except for Didang and Iniang, which replaced Dading and Isang; the latter would later be reintroduced in 1972 for reasons still unknown. The Philippine Weather Bureau and its successor PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in gray.


Season effects

[edit]

This table will list all the storms that developed in the northwestern Pacific Ocean west of the International Date Line and north of the equator during 1968. It will include their intensity, duration, name, areas affected, deaths, missing persons (in parentheses), and damage totals. Classification and intensity values will be based on estimations conducted by the JMA, however due to lack of information around this time sustained winds were recorded by the JTWC. All damage figures will be in 1968 USD. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical low.
