Pacific typhoon seasons
1991, 1992, 1993, 1994, 1995

The 1993 Pacific typhoon season has 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.

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 1993 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 Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.

Category 4 typhoon (SSHS)
Duration August 1 – August 10
Intensity 155 km/h (100 mph) (10-min),  922 mbar (hPa)

The near equatorial trough spawned a tropical depression on July 30 over the open Western Pacific waters. It tracked to the west-northwest, becoming a tropical storm on the 2nd and a typhoon on the 4th. Robyn turned more to the northwest, where it reached a peak intensity of 140 mph (230 km/h) winds on the 7th. It weakened to a 100 mph (200 km/h) typhoon before hitting southwestern Japan on the 9th, and became extratropical on the 11th over the Sea of Japan. Robyn caused 45 fatalities, 39 of which were from traffic related accidents, and $68 million in damage (1993 USD).

Typhoon Steve (Pining)

Severe tropical storm (JMA)

Intensity 165 km/h (105 mph) (10-min),  944 mbar (hPa)

Keoni formed southeast of the Big Island of Hawaii on August 9, and was later classified as a named system south of the island chain. 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.

Typhoon Vernon

Typhoon (JMA)
Category 1 typhoon (SSHS)
Duration August 21 – August 28

The monsoon trough formed a tropical depression on August 27. It headed generally westward, reaching tropical storm strength on the 30th and typhoon strength on the 31st. Yancy turned to the northeast, where it rapidly intensified to a 150 mph (240 km/h) super typhoon on the 2nd. The storm weakened to a 135 mph (217 km/h) typhoon before making landfall on southwestern Japan on the 3rd, and dissipated 2 days later over the Sea of Japan. Yancy brought strong winds to Japan, amounting to 42 casualties and widespread damage.

Typhoon Kyle (Luring)

Typhoon (JMA)
Category 2 typhoon (SSHS)
Duration November 19 – November 24
Intensity 130 km/h (80 mph) (10-min),  949 mbar (hPa)

Typhoon Lola (Monang)

Typhoon (JMA)
Category 3 typhoon (SSHS)
Duration December 1 – December 9
Intensity 150 km/h (90 mph) (10-min),  938 mbar (hPa)

The near equatorial trough spawned a tropical depression on November 27. It moved westward without significant development until December 2, when it became a tropical storm. Lola became a typhoon 2 days later, and hit the Philippines on the 5th. It weakened to a tropical storm after crossing the islands, but restrengthened to a 120 mph (190 km/h) typhoon before hitting southern Vietnam on the 8th. Lola quickly dissipated, not after causing 308 fatalities, 230 of which were in the Philippines from the heavy rains.

Typhoon Manny (Naning)

Typhoon (JMA)
Category 4 typhoon (SSHS)
Duration December 3 – December 16
Intensity 140 km/h (85 mph) (10-min),  922 mbar (hPa)

Manny, like Lola, developed from the near equatorial trough on December 1. It headed westward, slowly strengthening to a tropical storm on the 4th. Due to a ridge to the north, it looped on the 7th and 8th and became a typhoon on the way. While heading southwestward towards the Philippines, Manny rapidly intensified to a 140 mph (230 km/h) typhoon before hitting the Philippines late on the 9th. 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. However, it has a near perfect analog; Typhoon Pamela in the 1982 Pacific typhoon season took a nearly identical track within days of Manny (though Pamela was much weaker than Manny).

Tropical Depression Oning

This system was not recognised by the JTWC.

Typhoon Nell (Puring)

Severe tropical storm (JMA)
Category 1 typhoon (SSHS)
Duration December 20 – December 28
Intensity 110 km/h (70 mph) (10-min),  976 mbar (hPa)

One central Pacific storm, Hurricane Keoni, crossed into this basin. It became Typhoon Keoni, keeping its original name and "C" suffix.

Philippines

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) used its own naming scheme for tropical cyclones within its area of responsibility. Lists were recycled every four years. This was the list set for 1993.[4]

  • Atring
  • Bining
  • Kuring
  • Daling
  • Elang
  • Goring
  • Huling
  • Ibiang
  • Luming
  • Miling
  • Narsing
  • Openg
  • Pining
  • Rubing
  • Saling
  • Tasing
  • Unsing
  • Walding
  • Yeyeng
  • Anding
  • Binang
  • Kadiang 26W
  • Dinang
  • Epang
  • Gundang

Because the season exhausted the seasonal names, they used the following names. This was the first time since 1971 that extra names were needed in the Philippine region.

  • Husing
  • Indang
  • Luring
  • Monang 36W
  • Naning 37W
  • Oning
  • Puring
