1990 Pacific typhoon season

The 1990 Pacific typhoon season was another active season. It has no official bounds; it ran year-round in 1990, 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 1990 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.

On January 12, both the JMA and the JTWC identified a tropical depression in the northwest Pacific Ocean. The depression intensified over the period of a day to become a tropical storm on January 13, when it received the name Koryn from the JTWC. According to them, but not the JMA, Koryn reached hurricane-equivalent strength on January 15, when it peaked in intensity. The storm then weakened quite rapidly until it became extratropical on January 17, at 0000 UTC.

A tropical disturbance trekked across the Philippines in mid June, upon entering the South China Sea a depression formed. The depression was upgraded to Tropical Storm Nathan on June 16. Tropical Storm Nathan reached peak intensity of 65 mph (100 km/h) shortly before striking Hainan Island. In the South China Sea the Chinese ship Tien Fu sank killing 4 people. In southern China torrential rains caused flooding in Guangdong Province killing 10 people, two people drowned in Macau due to high waves. Tropical Storm Nathan then continued northwestwards making a final landfall near the Vietnam/China border.[2]

Winona 1990 track
DurationAugust 4 – August 11
Peak intensity110 km/h (70 mph) (10-min)  975 hPa (mbar)

The origins of Winona can be traced back to Severe Tropical Storm Tasha. On August 2, the remnant low of Tasha, as a patch of thunderstorms over northeastern China, was pushed to the east by a weather front from the west. By August 4, Tasha entered the Yellow Sea, before being pushed south by an anticyclone off northeastern Korea, into the East China Sea. Although the same system, Tasha was named Winona, as it started to strengthen into a tropical storm by August 7. It reached peak intensity with an eye-like feature on August 8, before landfalling over Japan the next day. Later, the remnants became extratropical.

Zola90
 
Zola 1990 track
DurationAugust 15 – August 23
Peak intensity140 km/h (85 mph) (10-min)  960 hPa (mbar)

On August 15, a large area of convection associated with the inflow of developing Typhoon Yancy was cut off, as Yancy was moving too fast to the west for the convection in the east to be absorbed into Yancy. By August 16, the convection developed a mid to low level circulation, and developed into tropical storm by August 18. Zola intensified into a typhoon by the next day, before reaching peak intensity on August 21. By the next day, Zola made landfall over Japan, before dissipating north of Japan. High winds and heavy rains produced by the storm killed three people and injured 22 others in Japan.

Typhoon Abe (Iliang)

Typhoon (JMA)
Category 2 typhoon (SSHWS)
Abe aug 30 1990 0545Z
 
Abe 1990 track
DurationAugust 23 – September 2
Peak intensity140 km/h (85 mph) (10-min)  955 hPa (mbar)

Forming on August 23 from a tropical disturbance, the depression which would eventually develop into Typhoon Abe initially tracked in a steady west-northwestward direction. As a result of an intense monsoon surge, the system's trajectory briefly changed to an eastward then northward path before returning to its original track. Abe only intensified by a small amount between 0000 UTC August 24 and 0600 UTC August 27 due to the disruptive effects of the surge, and on August 30, Abe peaked in intensity as a Category 2-equivalent typhoon on the Saffir–Simpson hurricane wind scale. After peaking in intensity, Abe crossed the Ryukyu Islands and the East China Sea, making landfall in China where it affected the provinces of Zhejiang and Jiangsu before entering the Yellow Sea, crossing South Korea, and finally transitioning into an extratropical cyclone.[6][7]

Typhoon Abe killed 108–195 people after it caused flooding and landslides in the Philippines and Taiwan, ravaged coastal areas of China, and brought high waves to Japan.[6][8][9] Abe, which is responsible for killing 108 in China, affected half of Zhejiang's land area and a fourth of its population, leaving thousands homeless and causing ¥3.5 billion yuan (RMB, $741.5–743 million USD) to be lost in damages.[7][9][10][11] Additional damage and one fatality occurred in Okinawa Prefecture in Japan, where at least ¥890 million yen (JPY, US$6 million) in damage was caused.[8][12][13]

Storm names

During the season 30 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list which started on mid-1989.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration 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 10 of which are published each year before the season starts. Names not retired from this list will be used again in the 1994 season. This is the same list used for the 1986 season. 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.

Retirement

Due to the severity of damage and loss of life caused by Mike, the name was retired and was replaced with Manny and was first used in the 1993 season. PAGASA also retired the name Ruping for similar reasons and was replaced with Ritang for the 1994 season.

1990 Atlantic hurricane season

The 1990 Atlantic hurricane season was the most active Atlantic hurricane season since 1969. It officially began on June 1, 1990, and lasted until November 30, 1990. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. One tropical depression did form before the season officially started, however.

Though very active, the season featured relatively weak systems, most of which stayed at sea. The 1990 season was unusual in that no tropical cyclone of at least tropical storm strength made landfall in the United States, although Tropical Storm Marco weakened to a depression just before landfall. 1962 was the last season prior to this one when no storm of at least tropical storm strength made landfall in the US. There have been a total of 6 such seasons in which no storms have made landfall in the United States at at least tropical storm strength; these were the 1853, 1862, 1864, 1922, 1962, and 1990 seasons.

Two of the season's hurricanes were notable. Hurricane Diana killed an estimated 139 in the Mexican states of Veracruz and Hidalgo; property damage estimates are unavailable, but damage was widespread. Hurricane Klaus brought flooding to Martinique, and caused torrential rainfall across the southeastern United States after combining with Tropical Storm Marco and a frontal boundary. As a result of effects from Diana and Klaus, both names were retired following the season.

1990 North Indian Ocean cyclone season

The 1990 North Indian Ocean cyclone season featured a below average total of twelve cyclonic disturbances and one of the most intense tropical cyclones in the basin on record. During the season the systems were primarily monitored by the India Meteorological Department, while other warning centres such as the United States Joint Typhoon Warning Center also monitored the area. During the season, there were at least 1,577 deaths, while the systems caused over US$693 million in damages. The most significant system was the 1990 Andhra Pradesh cyclone, which was the most intense, damaging, and the deadliest system of the season.

1990 Pacific hurricane season

The 1990 Pacific hurricane season was a very active season which observed 21 named storms within the basin. The season also produced the fourth highest ACE index value on record. The season was officially started on May 15 in the eastern Pacific, and on June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeastern Pacific Ocean. However, these bounds were slightly exceeded when Hurricane Alma formed on May 12.Hurricane Alma became the third earliest tropical cyclone in the Eastern Pacific basin since the satellite era began in 1966, while Trudy is the third strongest October eastern Pacific hurricane on record. Overall, the impact of this season was minimal. Tropical Storm Rachel made two landfalls in Mexico and brought rain to the United States. Hurricane Boris brought light showers to California.

Tropical Storm Winona (1990)

Tropical Storm Winona struck Japan during August 1990. An area of disturbed weather developed within the monsoon trough, located over the East China Sea, on August 4. Despite the presence of strong wind shear, a tropical depression developed later that day. The depression initially tracked northeast, bypassing the southern tip of Kyushu. Thereafter, the depression turned southeast, and on August 6, was believed to have obtained tropical storm intensity. In response to a building subtropical ridge to its southeast, Winona veered north while gradually intensifying. On August 9, Winona peaked in intensity, and while near peak intensity, made landfall in Shizuoka Prefecture early the following morning. Winona transitioned into an extratropical cyclone on August 11, and was last observed on August 14.

The tropical storm lashed the Japanese archipelago with heavy rains, strong winds, and waves up to 7.9 m (26 ft) high. More than 60 scheduled domestic air flights between Tokyo and western Japan were delayed or cancelled. Inter-island ferry service was suspended due to the storm. A total of 110 trains were cancelled or delayed, which led to 250,000 stranded passengers. Thirteen people suffered injuries, including three seriously. Seven reservoirs in Tokyo received more than 20,000,000 short tons (18,143,695 t) of water, which allowed authorities to lift restrictions on water use. Nearby, in Shizuoka Prefecture, 55 dwellings were flooded, resulting in 211 people homeless. Nationwide, over 400 roads were damaged and 43 landslides were reported. A total of 686 houses sustained flooding. In all, one fatality was attributed to the storm and damage was estimated at 8.74 billion yen or $60.3 million (1991 USD).

Typhoon Abe (1990)

Typhoon Abe, known as Typhoon Iliang in the Philippines, was the fourteenth named storm of 1990 Pacific typhoon season. Forming on August 23 from a tropical disturbance, the depression which would eventually develop into Typhoon Abe initially tracked in a steady west-northwestward direction. As a result of an intense monsoon surge, Abe's trajectory briefly changed to an eastward then northward path before returning to its original track. Abe only intensified by a small amount between 00:00 UTC August 24 and 06:00 UTC August 27 due to the disruptive effects of the surge, and on August 30, Abe peaked in intensity as a Category 2-equivalent typhoon on the Saffir–Simpson hurricane wind scale. After peaking in intensity, Abe crossed the Ryukyu Islands and the East China Sea, making landfall in China where it affected the provinces of Zhejiang and Jiangsu before entering the Yellow Sea, crossing South Korea, and finally transitioning into an extratropical cyclone.Typhoon Abe killed 108–195 people after it caused flooding and landslides in the Philippines and Taiwan, ravaged coastal areas of China, and brought high waves to Japan. Abe, which is responsible for killing 108 in China, affected half of Zhejiang's land area and a fourth of its population, leaving thousands homeless and causing ¥3.5 billion yuan (RMB, $741.5–743 million USD) to be lost in damages. Additional damage and one fatality occurred in Okinawa Prefecture in Japan, where at least ¥890 million yen (JPY, $6 million USD) in damage was caused.

Typhoon Flo (1990)

Typhoon Flo, known in the Philippines as Typhoon Norming, was a long-lived typhoon that brought destruction to much of Japan during September 1990. Flo originated from an area of convection that first formed to the southeast of the Marshall Islands on September 7. Five days later, the disturbance obtained tropical depression status, and on September 13, intensified into a tropical storm. Tracking west-northwest as it rounded a subtropical ridge, Flo slowly deepened, and on September 15, became a typhoon. After developing an eye, Flo began to rapidly intensify, and on September 17, Flo attained peak intensity. Shortly thereafter, the typhoon began to recurve to the northeast towards Honshu in response to deepening troughs to the northwest and north of the system, which resulted in a weakening trend due to increased vertical wind shear despite remaining over warm water. On September 19, Flo made landfall on southern Honshu, becoming the first typhoon to hit the Kii Peninsula in 11 years, and thereafter started to transition into an extratropical cyclone. The extratropical remnants of Flo were last noted on the morning of September 22.

Typhoon Flo was the strongest system to affect Japan since 1959. For a period of three days, the typhoon dropped heavy rainfall across much of the Japanese archipelago, which inflicted damage in 44 of 47 prefectures. The typhoon also passed just east of Okinawa, coming close enough to drop heavy rainfall. There, four people were killed, four were hurt, and five vessels sunk. On the northeastern side of Shikoku Island, in Kagawa Prefecture, two people were killed, 1,748 homes were damaged, and another 116 homes were destroyed. Across the Amami Islands, 13 people were killed, 29 others were hurt, 917 homes were damaged, and an additional 446 houses were destroyed, resulting in 2,327 homeless individuals. In Okayama Prefecture on the main Japanese island of Honshu, ten people perished and nine others were injured. There, 2,810 homes were demolished, 4,675 others were damaged, and Flo was the worst typhoon to strike the prefecture since 1964. While damage in Tokyo was slight, 260,000 passengers were stranded after 117 trains along the Tōkaidō Shinkansen line were disrupted. Due to a prolonged period of heavy rain, partially caused by Flo, rainfall was 300% of normal in some locations on the island as of mid-September 1990 while sunshine time was a mere 64% of average in Hokkaido Prefecture. Overall, 40 fatalities were reported and 131 others sustained injuries. A total 16,541 houses were destroyed while 18,183 others were flooded. Additionally, 413 ships sunk and 10,365 acres (4,195 ha) of farmland were damaged. The typhoon flooded or cut roads at 418 locations and railroads at 31 spots while there were also greater than 450 landslides. A total of 337 flights were canceled by Japan's four major airlines (Japan Airlines, All Nippon Airways, Japan Air System, and Air Nippon) affecting around 33,000 passengers. Moreover, 245 trains were halted, leaving almost 300,000 stranded. Monetary damage amounted to ¥132 billion or US$918 million across the country.

Typhoon Gene

Typhoon Gene, known in the Philippines as Typhoon Oyang, struck Japan during late September 1990. An area of disturbed weather formed several hundred kilometers south-southeast of Okinawa on September 18. Gradual development occurred as it tracked generally westward, and on September 22, the disturbance developed into a tropical depression. The depression intensified into a tropical storm the next day. Continuing to steadily intensify, Gene turned northwest and became a severe tropical storm on September 25. In the evening, Gene was declared a typhoon, and on September 26, attained its maximum intensity. Gene leveled off in intensity while recurving towards Japan. After brushing Kyushu and Shikoku on September 29 and Honshu on September 20, Gene weakened back to a tropical storm. On September 30, Gene transitioned into an extratropical cyclone, which was last noted on October 1.

The typhoon hit the Japanese archipelago ten days after Typhoon Flo, which killed 40 people. The southwestern portion of the country suffered the worst damage from the typhoon. Nationwide, six fatalities were reported and twenty others sustained injuries. In Miyazaki Prefecture, three people were killed and ten others were wounded. Throughout the prefecture, 4,688 houses were damaged and ninety-two others were destroyed, which led to 18,449 homeless. A total 210 houses were destroyed while 13,318 others were flooded. Elsewhere, 229 houses were damaged in Kagoshima Prefecture and seventy more were destroyed; consequently, 194 people lost their homes. There, almost 30,000 homes lost power. Overall, there were 340 landslides and roads were damaged at 182 locations. All Nippon Airways cancelled ninety domestic flights and Japan Airlines cancelled ten flights. Over 200,000 people were affected by cancellation of flights and train services. Thirty-one ships and 10,560 acres (4,273 ha) of farmland were damaged. Monetary damage estimates reached ¥22.9 billion yen or $158 million USD in 1990 values.

Typhoon Hattie (1990)

Typhoon Hattie, known in the Philippines as Typhoon Pasing, was the fifth tropical cyclone of a record-six to hit Japan during the 1990 Pacific typhoon season. Hattie originated from an area of disturbed weather that developed within the Western Pacific monsoon trough towards the end of September. Tracking westward, the disturbance initially was slow to develop, although on September 30, the system was classified as a tropical depression. Following an improvement of its convective structure and an increased in associated convection, the depression was upgraded into Tropical Storm Hattie on October 1. Following the development of an eye, Hattie attained typhoon intensity on October 2. The typhoon continued to slowly deepen as its forward speed slowed down. Despite a decrease in cloud top temperatures around the eye, Hattie was estimated to have attained peak intensity on October 5. After recurving to the north and then northeast, Hattie began to slowly weaken due to increased wind shear. On October 7, Hattie lost typhoon intensity, and after tracking directly over Tokyo, transitioned into an extratropical cyclone on the next day.

Although the inner core of Typhoon Hattie stayed offshore Japan, torrential rains were accountable for 68 landslides through the country. A total of 1,100 homes were flooded. Three people were killed, one was reported missing and nineteen others were injured, including six in Kyoto. Elsewhere, power lines were downed in 1,035 spots in Okinawa, mostly from sugar cane, vegetables, and flowers. Nationwide, damage was estimated at $9.9 million (1990 USD).

Typhoon Mike

Typhoon Mike, known in the Philippines as Typhoon Ruping, of 1990 was the strongest typhoon to hit the Philippines since Typhoon Irma in 1981. Forming from an area of persistent convection over the Caroline Islands, Mike was first designated on November 6, 1990 and moved generally westward. Later that day, the depression strengthened to Tropical Storm Mike near Yap. Mike became a typhoon early on November 9, and subsequently entered a period of rapid deepening. Late on November 10, the typhoon reached its maximum intensity of 115 mph (185 km/h), as estimated by the Japanese Meteorological Agency. After weakening slightly, Mike made landfall in the central Philippines, after weakening slightly. The storm weakened considerably due to land interaction, only to briefly re-intensify on November 14. Typhoon Mike turned west-northwest and later north-northwest, avoiding land interaction with Vietnam. Vertical wind shear increased, and on November 15, Mike weakened below typhoon intensity. Early the next day, the storm passed over western Hainan Island, and degraded to a tropical depression that night. After briefly emerging into the Gulf of Tonkin, Mike passed over southern China, where it dissipated on November 18.

During its formative stages, Mike passed just north of Palau. There, one person was hurt and around 90% of the banana and coconut crops were leveled. A total of 1,035 houses and 10 businesses were damaged. Damage on the island totaled $2 million, including $1.3 million in property damage. After striking the Philippines, the typhoon brought widespread damage and was considered the worst typhoon to hit the country since Typhoon Ike in 1984. In Cebu City, 88 ships sunk, the most ships ever sunk at the Cebu City harbor during a tropical cyclone. Power and phone lines were downed and the city lost access to drinking water for two days. Approximately 60% of all buildings were demolished and 28 people perished in the city. Nationwide, 748 people were killed while 1,274 others suffered injuries. A total of 1,900,000 t (2,094,390 short tons) of sugar crops were destroyed. A total of 630,885 homes were damaged and 222,026 houses were demolished, resulting in 1,110,020 people displaced. Offshore, 159 vessels sunk and 28 others were washed aground and damaged. Monetary damage was estimated at $446 million (₱10.8 billion), including $46.1 million (₱1.12 billion) from crops, $350 million (₱8.52 billion) from public infrastructure, and $49.9 million (₱1.21 billion) from private infrastructure. At the time, Mike was the costliest tropical cyclone listed in the National Disaster Risk Reduction and Management Council's database, and as of 2014, is the seventh costliest typhoon to strike the country since independence in 1947. Elsewhere, 68 people were killed in Vietnam, but no damage was reported in China.

Typhoon Ofelia

Typhoon Ofelia, known as Typhoon Bising in the Philippines, was the first of two typhoons in 1990 to directly affect the Philippines within a week. Typhoon Ofelia originated from an area of disturbed weather embedded in the monsoon trough situated near the Caroline Islands. Slowly organizing, the disturbance tracked westward, and was designated a tropical depression on June 15. After an increase in convection, the depression was upgraded into a tropical storm on June 17. On June 19, Ofelia turned northwest and after development of a central dense overcast, Ofelia was upgraded into a typhoon late on June 20. After turning north, Ofelia obtained its maximum intensity following the development of an eye. The typhoon skirted past the northeastern tip of Luzon and near the east coast of Taiwan, commencing a rapid weakening trend. On the evening on June 23, Ofelia struck the southern portion of Zhejiang. The storm then began to track north, recurving towards the Korean Peninsula. The storm tracked through the province of Jiangsu, and at 00:00 UTC on June 24, transitioned into an extratropical cyclone, only to merge with a frontal zone on June 25.

Although the inner core avoided the Philippines, the storm's large size resulted in inundation across the northern Philippines. The province of La Union was the hardest hit by the typhoon, where 22 people were killed and 90 homes were crushed. Three children perished and six others sustained injuries in Pasig. Overall, 56 people were killed and over 85,000 individuals were forced to flee their homes. Taiwan bore a direct landfall from Ofelia, dropping up to 460 mm (18 in) of rain. Hualien City was the hardest hit by the typhoon, where five people were killed. In all, Ofelia was the worst to hit eastern Taiwan in 30 years. More than 200 houses were destroyed or damaged and roughly 8,500 ha (21,005 acres) of rice paddies and vegetables were flooded. Roads and highways were blocked by landslides and floods. Agricultural losses exceeded NT$2.55 billion (US$94.7 million). Seventeen people died and twenty-three were missing due to flooding and mudslides. Although during a weakening phase at the time, the typhoon drenched central China. In Wenzhou, 12 people were killed and monetary damage was estimated at about 205 million RMB (US$42.8 million). In the province of Zhejiang, 15 fatalities were reported and 21 others were injured. In the neighboring province of Fujian, 15 people perished and 9,044 houses were demolished. About 91,000 ha (224,865 acres) of farmland were inundated and damage was estimated at 338 million RMB (US$70.5 million). Nationwide, 40 people were killed by Ofelia.

Typhoon Page (1990)

Typhoon Page, known in the Philippines as Typhoon Tering, was the fourth tropical cyclone to strike Japan in three months and the sixth in 1990. An area of disturbed weather developed on November 5 near the International Date Line. For more than two weeks, the disturbance failed to develop appreciably while it tracked generally westward. The disturbance began to organize on November 17. Four days later, the disturbance was designated a tropical depression, and on November 22, the depression was classified as a tropical storm. After resuming a westward course, Page intensified into a typhoon on November 4. Page then entered a period of rapid deepening before plateauing in intensity early on November 26. Page turned northwest, north, and later northeast as it rounded a subtropical ridge. Because of the change in steering, Page began to encounter stronger wind shear, which resulted in a prolonged weakening trend. On November 30, Page, just offshore Honshu, weakened below typhoon intensity, and became an extratropical cyclone on the same day after making landfall in central Honshu.

Typhoon Page was the record sixth tropical cyclone to directly affect Japan that year. It also was the latest typhoon to hit the country, with the previous mark set by Typhoon Agnes of the 1948 Pacific typhoon season. In Tokyo, 61 homes were damaged and 16 were destroyed. Elsewhere, in Mie Prefecture, 276 homes were damaged and 9 other homes were destroyed. Overall, four fatalities were reported and twelve others suffered injuries. A total of 162 homes were destroyed while 1,544 other houses were flooded. Nearly 35 ha (85 acres) of farmland were damaged. Total damage was estimated at 4.8 billion yen ($33 million USD).

Typhoon Percy (1990)

Typhoon Percy was the third tropical cyclone to affect the Philippines in 1990. The tenth tropical cyclone, sixth tropical storm, and third typhoon of the 1990 Pacific typhoon season, Typhoon Percy originated from an area of disturbed weather spawned by the Western Pacific monsoon trough on June 20. That same day, the disturbance was classified as a tropical depression as it slowly organized and on June 21, the depression obtained tropical storm intensity. After initially tracking westward, Percy turned towards the southwest while slowly deepening. During this time, Percy affected several of the Carolina Islands. Thirty homes were damaged and airline services were halted in and out of Yap. Farther south-southwest, seven homes were destroyed on the Ngulu Atoll. Furthermore, one boy was killed on Koror, where numerous homes lost their roof and communication lines were downed. Percy then turned back to the west-northwest and became a typhoon on June 23. It then began to deepen at a faster clip, with Percy attaining maximum intensity on June 25. Two days later, increased wind shear began to induce a weakening trend and also on June 27, the typhoon brushed Luzon. There, eight people were killed and over 30,000 individuals lost their homes. Damage in the country was minor, however.

After tracking through the South China Sea, Percy made landfall southwest of Xiamen on June 29, and on the next day, dissipated inland. In the province of Quanzhou, four people were killed while 100,000 trees were damaged along with 1,000 power lines. One person was killed in Zhangzhou. In Dongshan, one individual died, four others suffered injuries, and a third of the trees were downed. Moreover, in the province of Shantou, 95 structures were destroyed and 201 were damaged. Sixteen people were killed throughout southeastern China and more than 100 others sustained injuries. Damage was estimated at US$28 million.

Typhoon Zola

Typhoon Zola struck Japan during August 1990. An area of disturbed weather developed during mid-August to the west of Guam. The disturbance developed into a tropical depression on August 16 while tracking eastward. Decreased wind shear aided in intensification, and it is estimated that the depression strengthened into a tropical storm on August 17. Continuing to intensify, Zola turned northwest in response to a subtropical ridge to its east before obtaining typhoon intensity on August 20. Typhoon Zola reached its peak intensity the next day. After weakening slightly, the storm moved ashore on Honshu. On August 23, the system transitioned into an extratropical cyclone over the Sea of Japan.

The typhoon dropped heavy rains across much of the Japanese archipelago. Near where the storm moved over ashore, in Kōchi Prefecture, three people were injured. Thirty-eight homes were damaged or destroyed. Further north, 7 people were injured in Hiroshima Prefecture, where 30 houses were damaged or destroyed, and 19 others were flooded. Power lines were cut in 84,000 locations and 2,100 ha (5,190 acres) of farmland were damaged in the prefecture. Nationwide, six people were killed while twenty-four others were hurt. A total 67 houses were destroyed while 420 others were flooded. A total of 16 ships and 4,560 acres (1,845 ha) of farmland were damaged. Over 250 flights were called off. In all, damage totaled ¥15.1 billion, equal to US$104 million.
