The 1989 Pacific typhoon season has no official bounds; it ran year-round in 1989, 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.
[edit] Overview
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 1989 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.
[edit] Storms
35 tropical cyclones formed this year in the Western Pacific, of which 31 became tropical storms. 21 storms reached typhoon intensity, of which 6 reached super typhoon strength.

[edit] Super Typhoon Andy
[edit] Typhoon Brenda
A tropical depression which formed in the monsoon trough on May 14 became a tropical storm on the 16th and struck Samar Island and souther Luzon in the Philippines that day. At least 4 ships sand and 50 people were killed in the Philippines. Brenda became a typhoon and reached a peak of 85 mph (137 km/h) winds before hitting southern China on the 20th. The storm brought torrential flooding, resulting in at least 84 casualties and widespread damage in China. In Hong Kong six people were killed and one was missing due to landslides and flooding.[3]
[edit] Typhoon Cecil
The day after Brenda dissipated another tropical depression formed in the South China Sea from the monsoon trough. It became a tropical storm later on the 22nd, and reached typhoon strength on the 24th. Cecil initially tracked to the northwest, but ridging to the north forced the typhoon westward where it hit central Vietnam on the 24th. Cecil rapidly dissipated, but not after bringing heavy flooding that killed 52 and left over 100,000 homeless.[4]
[edit] Typhoon Dot
Forming south of the central Caroline Islands, Dot moved steadily west-northwest across the Philippines through the South China Sea across southern Hainan island into northern Vietnam.[5]
[edit] Tropical Storm Ellis
Developing as a disturbance in the Philippine Sea on June 18, the system moved westward initially and became a tropical depression late on June 20 and weakened on June 21. Early on June 23, the large system with gales well removed from its center became a tropical depression once more. A trough to its northwest had deepened, which was accelerating the cyclone northward. It became a minimal tropical storm during this accleration. Late that day, it became a frontal wave before moving through Japan into the Sea of Japan.[6]
[edit] Tropical Storm Faye
[edit] Super Typhoon Gordon/Goring
A single Cumulonimbus cloud beneath the Tropical Upper Tropospheric Trough developed into a weak tropical depression on July 9. It tracked westward with a cold core upper level low aloft, a very unusual circumstance. Initially forecasted to remain weak due to the lack of upper level outflow, it was able to strengthen into a tropical storm on the 12th. The cold low quickly warmed, and Gordon became a typhoon on the 13th. It rapidly intensified on the 14th and 15th to a 160 mph (260 km/h) super typhoon, and hit northern Luzon later that day at that intensity. It steadily weakened as hit moved westward, and made landfall on southern China, 100 miles (160 km) southwest of Hong Kong, as a 70 mph (110 km/h) tropical storm on the 18th. Gordon caused 97 casualties[7] and left 120,000 homeless.[8]
[edit] Tropical Storm Hope
A tropical depression formed in the wake of Super Typhoon Gordon on the 16th of July. The depression moved towards the northwest and strengthened into Tropical Storm Hope. Hope moved approximately 100 miles (160 km) south of Okinawa and then strengthened to a peak of 65 mph (105 km/h) while nearing the China coastline. Hope made landfall on the east China coastline on July 21st. Heavy rains caused widespread flooding and landslides resulting in 24 casualties.[9]
[edit] Tropical Storm Irving
Tropical Storm Irving formed in the South China Sea west of the Philippines on July 21st. Although hampered by northerly sheer Irving intensified to a peak of 65 mph (105 km/h) just before landfall in northern Vietnam. In Vietnam 102 people were killed due to Tropical Storm Irving's passage.[10]
[edit] Typhoon Judy
[edit] Tropical Storm Ken-Lola
The monsoon trough spawned a tropical depression on July 29. Poorly organized, it moved quickly northeastward and became a tropical storm on the 30th. Operationally, Tropical Storm Ken continued northeastward with the rest of the convection, with Tropical Storm Lola forming further westward, but the ill-defined circulation actually continued westward, leading to one storm with two names. Ken-Lola turned to the southwest, stalling before heading northwest again. Ken-Lola reached a peak of 60 mph (97 km/h) winds before hitting eastern China on the 3rd, causing little damage as it slowly dissipated until the 7th.[11] Ken-Lola shows the troubles of tracking poorly organized systems. A more recent example is Tropical Depression 32W/33W in 1995.
[edit] Typhoon Mac
Moving around the northeast side of Ken-Lola, and then an upper tropospheric cyclone Mac moved along a wide northwest arc before settling on a north-northwest track into Japan as a typhoon on August 6, dissipating over Sakhalin Island on August 8.[12]
[edit] Typhoon Nancy
[edit] Typhoon Owen
[edit] Tropical Storm Peggy
[edit] Tropical Storm Roger
A tropical disturbance began to organize just to the north of Taiwan while moving eastwards. The disturbance consolidated to a depression on the 24th of August and was named Tropical Storm Roger the next day. Roger then abruptly turned towards the northeast and accelerated. Roger reached peak intensity of 60 mph (97 km/h) just before landfall at Cape Muroto on Shikoku Island. 19 inches of rain fell across Honshū Island as Tropical Storm Roger moved through, the resulting landslides and floods killed 3 people.[13]
[edit] Typhoon Sarah
On September 9, Typhoon Sarah, which formed on the 3rd, stalled east of the Philippines, bringing heavy rain and rare tornadic activity to the country. Sarah turned northward, where it rapidly intensified to a 145 mph typhoon on the 11th. The system had 2 main centers, causing it to loop while south of Taiwan before crossing the island on the 12th. Sarah continued northwestward, and dissipated over eastern China on the 14th. 44 casualties can be attributed to this system.[14]
[edit] Tropical Storm Tip
Tip formed along the eastern portion of the monsoon trough, and tracked northeast until the subtropical ridge blocked its motion in that direction. Rounding the western periphery of the ridge, Tip eventually recurved well offshore Japan and became an extratropical cyclone.[15]
[edit] Tropical Storm Vera
Tropical Storm Vera, which formed on September 11, hit eastern China on the 15th as a 45 mph (72 km/h) storm. Torrential rains and flooding caused more than 500 casualties and extensive crop damage.[16]
[edit] Typhoon Wayne
Typhoon Wayne formed from a depression on the 17th of September about 100 miles (160 km) southwest of Okinawa. Tropical Storm Wayne was named the next day and into a typhoon on the 19th. Wayne reached peak intensity of 75 mph (121 km/h) before beginning to accelerate toward the northeast. Typhoon Wayne skimmed the southeastern island of Japan while weakening into a tropical storm. Heavy rains fell throughout southern Japan and 7 people died from the resulting landslides and flooding.[17]
[edit] Super Typhoon Angela
When the small Super Typhoon Angela, which developed on September 28, hit northern Luzon on October 5, it caused 62 fatalities (with 50 missing) and massive damage from flooding and mudslides. Over the next 12 days, the Philippines would be hit by 2 more typhoons; Dan and Elsie.[18]
[edit] Typhoon Brian
While Super Typhoon Angela was forming in the Philippine Sea an area of convection formed about 390 miles (630 km) southeast of Hong Kong. As the area of convection became stationary in the South China Sea a tropical depression formed on the 28th of September. Tropical Storm Brian was named on the 29th as the storm moved towards the west-northwest, Brian strengthened to a typhoon the next day. Typhoon Brian reached peak intensity of 95 mph (153 km/h) just 20 miles (32 km) off the southeast coast of Hainan Island. Typhoon Brian dropped heavy rains heavy flooding occurred and 31 people were killed as well as heavy damage to rice crops. After leaving Hainan Island Brian continued westward making a second landfall near Vinh, Vietnam before dissipating in the mountains of northern Vietnam.[19]
[edit] Typhoon Colleen
[edit] Typhoon Dan
The 2nd of 3 typhoons to hit the Philippines in a 12 day period, Dan hit the central part of the country on October 10 as a 75 mph (121 km/h) typhoon. It continued westward to hit Vietnam on the 13th where it dissipated. Dan, though a weak system, killed 41 people as it crossed the archipelago and left 232,555 people homeless.[20]
[edit] Super Typhoon Elsie
17 casualties can be attributed to Super Typhoon Elsie hitting Luzon as a 160 mph (260 km/h) super typhoon on October 19, just weeks after Angela and Dan hit the same area.[21]
[edit] Typhoon Forrest
The last of the tropical cyclones in October and the 17th typhoon of the year, Forrest was slow to develop initially near the Marshall Islands as it was a large cyclone. Once it passed Guam by only 140 km/85 mi, it intensified into a typhoon, with maximum sustained winds peaking at 95 kt/110 mph. Tree limbs and power lines were downed as the system pulled away from Saipan. It then recurved, accelerating northeast to become of the strongest extratropical cyclones in the Pacific Ocean that year.[22]
[edit] Typhoon Gay
- Main article: Typhoon Gay (1989)
Typhoon Gay was a Western Pacific typhoon that crossed the Malay Peninsula in early November. It continued westward, reaching a peak of 160 mph (260 km/h) winds before hitting India and dissipating on the 10th. Gay killed over 1,000 people.[23]
[edit] Typhoon Hunt
A tropical disturbance began to organize and a tropical depression formed east of the Philippines on the 16th of November. As the depression moved towards the northwest it strengthened into Tropical Storm Hunt which rapidly intensified becoming a typhoon while moving towards the northwest. Typhoon Hunt reached peak intensity of 105 mph (169 km/h) just before turning due west towards the Philippines. Hunt maintained peak intensity until landfall on central Luzon Island. 7 people were killed and minor damage occurred to U.S. Military operations. After departing the Philippines Hunt was downgraded and dissipated in the South China Sea.[24]
