The season had no official bounds; it ran year-round in 1993, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.

[1] These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center.

Typhoon Koryn, having developed well east of the Philippines on June 13, steadily strengthened as it moved westward, intensifying to a peak of 150 mph (240 km/h) winds on the 24th.

It crossed northern Luzon the next day as a slightly weaker 130 mph (210 km/h) typhoon, and continued west-northwestward until hitting southern China (90 nautical miles southwest of Hong Kong on the 27th).

Koryn slowly wound down, bringing heavy rain through China and northern Vietnam before dissipating on the 29th.

Koryn was responsible for the loss of 37 people, as well as $14.5 million (1993 USD) in damage over the northern Philippines.

[4] The near equatorial trough spawned a tropical depression on July 30 over the open Western Pacific waters.

Robyn caused 45 fatalities, 39 of which were from traffic related accidents, and $68 million in damage (1993 USD).

Keoni peaked as an intense Category 4 hurricane over open waters and lasted until the 29th, crossing the International Date Line and becoming a typhoon in the western Pacific, but never affected land.

Yancy brought strong winds to Japan, amounting to 42 casualties and widespread damage.

Abe brought strong winds and heavy rain to Taiwan as it passed south of the island.

Becky was clearly underestimated and the hurricane signal 10 should have been hoisted as it was justified (hurricane-force winds recorded at southwestern part of Hong Kong when Becky traversed at about 110 km south-southwest of the Royal Observatory).

Its maximum 10 minute sustained wind speed was estimated to be at around 150 km/h at its closet approach to Hong Kong.

Initially posing a direct hit to Hong Kong but it slowly moved north, striking the coast of western Guangdong.

It also wreaked havoc in Hong Kong, causing an aircraft to slide off the runway at Kai Tak Airport after landing in blind weather.

It weakened to a tropical storm after crossing the islands, but restrengthened to a 125 mph (200 km/h) typhoon before hitting southern Vietnam on the 8th.

It weakened over the islands, and upper level winds kept it from restrengthening much over the South China Sea.

Manny dissipated on the 16th over the Malay Peninsula, after causing 230 deaths, only one week after Lola hit the same area.

Manny's track was unusual, given its time of year with a loop and a strengthening period to the southwest.

It moved in a fairly fast westward direction as it gradually intensified into a weak tropical depression late on December 14.

The PAGASA issued warnings on the depression as it reached peak intensity late on December 15, making landfall over the islands of Visayas.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility.

This table summarizes all the systems that developed within or moved into the North Pacific Ocean, to the west of the International Date Line during 1993.
