1971 Pacific typhoon season
Encyclopedia
The 1971 Pacific typhoon season has no official bounds; it ran year-round in 1971, 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.

It briefly weakened to a tropical storm on the 11th, but restrengthened to a typhoon as it continued westward. On August 13, Typhoon Rose made landfall on northeastern Luzon
with winds of 130 mi/h. It weakened to a minimal typhoon over the mountainous terrain, but in the South China Sea, Rose rapidly intensified, and peaked at 140 mi/h winds on the 16th. As it approached the coast of Hong Kong, the inflow became disrupted, but Rose still hit as a 100 mi/h typhoon on the 16th. The typhoon dissipated the next day, after causing 130 deaths in Hong Kong and leaving 5,600 people homeless. A Macao ferry was capsized, resulting in the loss of its 88 person crew.

Super Typhoon Lucy (Rosing)
The strongest typhoon to strike the Philippines that year, this cyclone moved towards the region from the Marianas as a slow pace. Gusty southwest winds impacted western portions of Visayas and Luzon, including Manila, as the cyclone passed by on the 21st. The highest winds recorded were 190 kilometres per hour (96.9 kn) at Basco in Batanes. Heavy rains caused by the strong onshore flow led to heavy rains, which peaked at 379.5 millimetres (14.9 in) at Baguio City within 24 hours. The heavy rains led to severe flooding and landslides in north-central sections of the Philippines.Super Typhoon Nadine (Sisang)
Typhoon Nadine, which formed on July 20, quickly strengthened to a peak of 175 mi/h on the 24th. It weakened slightly as it continued its northwest movement, and struck eastern TaiwanTaiwan
Taiwan , also known, especially in the past, as Formosa , is the largest island of the same-named island group of East Asia in the western Pacific Ocean and located off the southeastern coast of mainland China. The island forms over 99% of the current territory of the Republic of China following...

The typhoon dissipated the next day, after causing 130 deaths in Hong Kong and leaving 5,600 people homeless. A Macao ferry was capsized, resulting in the loss of its 88 person crew.
Typhoon Trix
An upper level low contributed to the birth of Tropical Storm Trix on August 20. After drifting northward, the storm turned to the west in response to the building of the subtropical ridge. Trix slowly strengthened after becoming a typhoon on the 21st, and reached a peak of 115 mi/h winds on the 28th. Trix recurved, and struck southwestern Japan on the 29th as a 95 mi/h typhoon. It accelerated to the northeast, and became extratropical on the 30th. Just weeks after Typhoon Olive, Trix dropped more heavy rain to the country, in one case as much as 43 inches (1,092.2 mm) of rain. Trix caused 44 deaths, with heavy crop damage amounting to $50.6 million.Typhoon Virginia
Within one month of Typhoons Trix and Olive, Typhoon Virginia came up the Japanese coast with winds of 80 mi/h. It became extratropical on September 7 just east of Japan, after dropping more heavy rain causing 56 casualties from numerous landslides.Super Typhoon Bess (Yayang)
Super Typhoon Bess, having peaked at 160 mi/h on July 5, tracked west-northwestward. The typhoon weakened as it continued its movement, and struck eastern TaiwanTaiwan

Typhoon Faye (Dadang)
A tropical disturbance east of the Marianas Islands developed into Tropical Storm Faye on October 4. After peaking at 75 mi/h on the 5th, Faye became very disorganized, and weakened to a tropical depression on the 7th. At this time, there were several circulations, so it is possible that Faye was absorbed by another disturbance to its south. Regardless, the storm re-organized as it approached the PhilippinesPhilippines

The 1971 Pacific typhoon season has no official bounds; it ran year-round in 1971, 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.

or PAGASA. This can often result in the same storm having two names.
Storms
38 tropical depressions formed this year in the Western Pacific, of which 35 became tropical storms. 24 storms reached typhoon intensity, of which 6 reached super typhoon strength. The season had an extremely active start, with 11 storms forming before July 1 and 19 storms before August 1. According to the JMA, three named storms formed in April and eight in July. Those totals are records for any season. Also, four named storms formed in May, a record tied with the 1980 season1980 Pacific typhoon season

. The westerlies brought Wanda to the north and northeast, where it weakened until dissipating on the 4th near Hainan Island. The storm caused 56 deaths (with 39 missing) and $700,000 in damage (1971 USD) from the heavy flooding.
Super Typhoon Lucy (Rosing)
The strongest typhoon to strike the Philippines that year, this cyclone moved towards the region from the Marianas as a slow pace. Gusty southwest winds impacted western portions of Visayas and Luzon, including Manila, as the cyclone passed by on the 21st. The highest winds recorded were 190 kilometres per hour (96.9 kn) at Basco in Batanes. Heavy rains caused by the strong onshore flow led to heavy rains, which peaked at 379.5 millimetres (14.9 in) at Baguio City within 24 hours. The heavy rains led to severe flooding and landslides in north-central sections of the Philippines.Super Typhoon Nadine (Sisang)
Typhoon Nadine, which formed on July 20, quickly strengthened to a peak of 175 mi/h on the 24th. It weakened slightly as it continued its northwest movement, and struck eastern TaiwanTaiwan
Taiwan , also known, especially in the past, as Formosa , is the largest island of the same-named island group of East Asia in the western Pacific Ocean and located off the southeastern coast of mainland China. The island forms over 99% of the current territory of the Republic of China following...
on the 25th with winds of over 100 mi/h. Nadine dissipated the next day over China, after causing 28 deaths (with 25 missing) and heavy damage on Taiwan from the flooding. Nadine also caused the crash of a Pan American cargo aircraft, killing all four people in the crew.
Typhoon Olive
85 mi/h Typhoon Olive, which developed on July 29 from the near equatorial trough, hit southwestern Japan on August 4. It continued northward, and became extratropical in the Sea of JapanSea of Japan

. Olive's heavy rains resulted in numerous mudslides, killing 69 people.
Typhoon Rose (Uring)

organized into Tropical Storm Rose on August 10. An extremely small cyclone with a wind field of 150 nautical miles (277.8 km) across, Rose quickly strengthened, and became a typhoon later that day. It briefly weakened to a tropical storm on the 11th, but restrengthened to a typhoon as it continued westward. On August 13, Typhoon Rose made landfall on northeastern Luzon

with winds of 130 mi/h. It weakened to a minimal typhoon over the mountainous terrain, but in the South China Sea, Rose rapidly intensified, and peaked at 140 mi/h winds on the 16th. As it approached the coast of Hong Kong, the inflow became disrupted, but Rose still hit as a 100 mi/h typhoon on the 16th. The typhoon dissipated the next day, after causing 130 deaths in Hong Kong and leaving 5,600 people homeless. A Macao ferry was capsized, resulting in the loss of its 88 person crew.
Typhoon Trix
An upper level low contributed to the birth of Tropical Storm Trix on August 20. After drifting northward, the storm turned to the west in response to the building of the subtropical ridge. Trix slowly strengthened after becoming a typhoon on the 21st, and reached a peak of 115 mi/h winds on the 28th. Trix recurved, and struck southwestern Japan on the 29th as a 95 mi/h typhoon. It accelerated to the northeast, and became extratropical on the 30th. Just weeks after Typhoon Olive, Trix dropped more heavy rain to the country, in one case as much as 43 inches (1,092.2 mm) of rain. Trix caused 44 deaths, with heavy crop damage amounting to $50.6 million.Typhoon Virginia
Within one month of Typhoons Trix and Olive, Typhoon Virginia came up the Japanese coast with winds of 80 mi/h. It became extratropical on September 7 just east of Japan, after dropping more heavy rain causing 56 casualties from numerous landslides.Super Typhoon Bess (Yayang)
Super Typhoon Bess, having peaked at 160 mi/h on July 5, tracked west-northwestward. The typhoon weakened as it continued its movement, and struck eastern TaiwanTaiwan
Taiwan , also known, especially in the past, as Formosa , is the largest island of the same-named island group of East Asia in the western Pacific Ocean and located off the southeastern coast of mainland China. The island forms over 99% of the current territory of the Republic of China following...
on the 9th as a 130 mi/h typhoon. It rapidly weakened over the country, and dissipated on the 10th over China. The typhoon caused heavy flooding, resulting in 32 deaths and moderate crop damage.
Typhoon Faye (Dadang)
A tropical disturbance east of the Marianas Islands developed into Tropical Storm Faye on October 4. After peaking at 75 mi/h on the 5th, Faye became very disorganized, and weakened to a tropical depression on the 7th. At this time, there were several circulations, so it is possible that Faye was absorbed by another disturbance to its south. Regardless, the storm re-organized as it approached the PhilippinesPhilippines
The Philippines , officially known as the Republic of the Philippines , is a country in Southeast Asia in the western Pacific Ocean. To its north across the Luzon Strait lies Taiwan. West across the South China Sea sits Vietnam...
. Faye crossed the islands on the 10th as a minimal tropical storm, and again became a typhoon in the South China Sea on the 11th. Steering currents became weak, and a northwest flow forced Faye southeastward back into the Philippines. Faye crossed the islands on the 12th, and dissipated on the 13th, after causing torrential rainfall killing 13 people with 80 missing. The death toll is combined with another Tropical Storm, Gloria, that hit the area days before Faye.
Typhoon Hester (Goying)
On October 19 and 20, Tropical Storm Hester developed and crossed the Southern Philippines. Upon moving northwestward through the South China Sea, Hester strengthened, reaching a peak of 100 mi/h winds just before striking central VietnamVietnam
