Pacific typhoon seasons
1969, 1970, 1971, 1972, 1973

The 1971 Pacific typhoon season was an extremely active season that featured the second highest typhoon count on record. It 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.

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 1971 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.

Note: Data begins at the year 1955 due to earlier data being increasingly unreliable. Totals for tropical storms and typhoons after 1964 are from the Japan Meteorological Agency, and totals for the unofficial super typhoon category are from the Joint Typhoon Warning Center.

According to the United States Joint Typhoon Warning Center, the 1971 season was the most active season since 1967, with a total of 35 tropical storms being monitored by them during the year.[1] In addition to the 35 tropical storms, the Japan Meteorological Agency considered Tropical Depression 25W to be an additional tropical storm, which was only classified as a tropical depression by the JTWC.[2]

Systems

Severe Tropical Storm Sarah

Severe tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationJanuary 8 – January 11
Peak intensity95 km/h (60 mph) (1-min);
990 hPa (mbar)

During January 8, the JMA started to monitor a tropical depression that had developed, about 500 km (310 mi) to the east of Ngerulmud, Palau.[3] Over the next day the system gradually developed further as it moved north-westwards, before it was classified as a tropical storm and named Sarah by the JTWC, after a US Navy plane had found an organised system.[3][4] The system subsequently recurved north-eastwards, before it was classified as a Severe Tropical Storm by the JMA during January 10.[5] During that day, the JTWC reported that the system had peaked, with 1-minute sustained wind-speeds of 95 km/h (60 mph).[4] Over the next day, the system quickly weakened and became an extratropical cyclone during January 11.[4] Sarah's extratropical remnants were subsequently tracked as they moved north-eastwards, until it made landfall on Canada and broke up over the mountains of British Columbia during January 17.[4]

Tropical Storm Thelma (Bebeng)

Tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationMarch 16 – March 21
Peak intensity85 km/h (50 mph) (1-min);
994 hPa (mbar)

On March 16, a tropical depression formed to the south of Guam. It immediately entered the Philippine Area of Responsibility, earning the local name Bebeng. It executed a small loop to the east of Mindanao before it traveled to the northwest. It exited the Area of Responsibility as a tropical storm before transitioning to an extratropical storm, southwest of Minami-Tori-shima. The extratropical storm weakened and dissipated on March 21, to the south-southeast of Japan.

Typhoon Vera (Karing)

Typhoon (JMA)
Category 2-equivalent typhoon (SSHWS)
 
DurationApril 6 – April 19
Peak intensity165 km/h (105 mph) (1-min);
965 hPa (mbar)

Typhoon Wanda (Diding)

Typhoon (JMA)
Category 1-equivalent typhoon (SSHWS)
 
DurationApril 22 – May 5
Peak intensity140 km/h (85 mph) (1-min);
980 hPa (mbar)

On April 23 Tropical Storm Wanda began its life to the east of the Philippines. It tracked over the archipelago, and emerged into the South China Sea on the 25th. It turned to the northwest, and became a typhoon on May 1 just off the coast of South Vietnam. 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 14 missing) and $700,000 in damage (1971 USD) from the heavy flooding across the Philippines.[6] While Wanda brushed the coast of Vietnam, the United States Army grounded most aircraft in northern areas and skirmishes related to the Vietnam War temporarily decreased until the storm passed by.[7] In Quảng Ngãi Province, 23 people were killed.[8]

Typhoon Amy

Typhoon (JMA)
Category 5-equivalent super typhoon (SSHWS)
 
DurationApril 27 – May 7
Peak intensity280 km/h (175 mph) (1-min);
890 hPa (mbar)

According to the JTWC best track, Amy was first noted as a tropical depression early on April 29. Amy reached tropical storm status shortly afterwards, and became a typhoon by early on May 1. The cyclone then rapidly intensified into a Category 5 super typhoon with 1-minute sustained winds of 280 km/h (175 mph) on May 2, with the JMA estimating a minimum central pressure of 890 mb (hPa; 26.28 inHg),[9] although the JTWC estimated a slightly higher pressure of 895 mbar (hPa; 26.43 inHg), while noting a compact eye 10 nautical miles across.[10] Although Amy weakened to a Category 4 super typhoon on May 3, it regained Category 5 intensity later that day, with 1-minute sustained winds of 260 km/h (160 mph) and a central pressure of 900 mb (hPa; 26.58 inHg). The storm began to weaken by May 4 and was last noted as producing tropical-storm force winds on May 7,[11] after which Amy was absorbed by a frontal system.[10]

In deepening to 890 mb, Amy became the most intense typhoon on record in May.[12][13] On Truk Atoll, now known as Chuuk Atoll, one person was killed after a coconut tree fell on him.[14] On May 18, the Federated States of Micronesia was declared a disaster area by the Federal Emergency Management Agency.[15] The weather station and over 2,250 homes were destroyed on Namonuito Atoll.[10]

Across the Philippines, Harriet was responsible for one fatality.[16]

Striking near the demilitarized zone between North and South Vietnam as a powerful typhoon, Harriet caused significant disruptions to the Vietnam War. Military operations on both sides were temporarily halted, with all United States helicopters grounded. Ground movement was severely limited as well. Despite the intensity of the storm, damage was relatively light, with Camp Eagle reporting some roofs blown off from 120 km/h (75 mph) winds.[17] In Đà Nẵng, between 8 and 10 in (200 and 250 mm) of rain fell and strong winds knocked out power to the area.[18] A 24‑hour maximum rainfall of 10.16 in (258 mm) was measured in Camp Evans. Throughout Vietnam, four people were killed and fourteen others were reported missing. Thừa Thiên Province sustained the most significant damage, with 2,500 homes damaged or destroyed.[16]

DurationJuly 13 – July 24
Peak intensity240 km/h (150 mph) (1-min);
910 hPa (mbar)

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 (100 kn) at Basco in Batanes. Heavy rains caused by the strong onshore flow led to heavy rains, which peaked at 379.5 millimetres (14.94 in) at Baguio City within 24 hours. The heavy rains led to severe flooding and landslides in north-central sections of the Philippines.[20]

Typhoon Mary

900 hPa (mbar)

Typhoon Nadine, which formed on July 20, rapidly intensified to a peak of 175 mph (282 km/h) on the 24th. It weakened slightly as it continued its northwest movement, and struck eastern Taiwan on the 25th with winds of over 100 mph (200 km/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.[citation needed]

960 hPa (mbar)
Main article: Typhoon Rose (1971)

A small circulation near Chuuk organized into Tropical Storm Rose on August 10. An extremely small cyclone with a wind field of 150 nautical miles (280 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 Palanan, Isabela with winds of 130 mph (210 km/h). It weakened to a minimal typhoon over the mountainous terrain, but after reemerging in the South China Sea, Rose rapidly intensified, and peaked at 140 mph (230 km/h) winds on the 16th. As it approached the coast of Hong Kong, the inflow became disrupted, but Rose still hit as a 100 mph (200 km/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 Shirley

Typhoon (JMA)

DurationAugust 19 – September 1
Peak intensity185 km/h (115 mph) (1-min);
915 hPa (mbar)

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 mph (185 km/h) winds on the 28th. Trix recurved, and struck southwestern Japan on the 29th as a 95 mph (153 km/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 (1,100 mm) of rain. Trix caused 44 deaths, with heavy crop damage amounting to $50.6 million.

Tropical Storm 25W

905 hPa (mbar)

Super Typhoon Bess, having peaked at 160 mph (260 km/h) on July 5, tracked west-northwestward. The typhoon weakened as it continued its movement, and struck eastern Taiwan on the 22nd as a 130 mph (210 km/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.[citation needed]

Severe tropical storm (JMA)
Category 1-equivalent typhoon (SSHWS)
 
DurationOctober 4 – October 15
Peak intensity120 km/h (75 mph) (1-min);
985 hPa (mbar)

A tropical disturbance east of the Marianas Islands developed into Tropical Storm Faye on October 4. After peaking at 75 mph (121 km/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 Philippines. 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.[6]

Typhoon Hester (Goying)

Typhoon (JMA)
Category 2-equivalent typhoon (SSHWS)
 
DurationOctober 18 – October 24
Peak intensity165 km/h (105 mph) (1-min);
970 hPa (mbar)
Main article: Typhoon Hester (1971)

Developing as a tropical depression on October 18 near Palau Island, Hester gradually intensified as it moved westward towards the Philippines.[21][22] Across the Philippines, Hester was responsible for six deaths and ₱5 million in damage.[6] After passing over Mindanao and the Visayas as a tropical storm between October 20 and 21, the storm intensified into a typhoon before striking Palawan. Once over the South China Sea, Hester further strengthened and ultimately attained peak winds of 165 km/h (105 mph). On October 23, the storm made landfall near Huế, South Vietnam. Once onshore, Hester rapidly weakened and dissipated on October 24 over Laos.[21][22]

The most significant impact from Typhoon Hester was felt in South Vietnam were winds in excess of 155 km/h (100 mph) caused extensive damage to several United States Army bases. The hardest hit base was in Chu Lai where three Americans were killed. At least 75 percent of the structures in the base sustained damage and 123 aircraft were damaged or destroyed.[21] Newspaper reports indicated that 100 Vietnamese lost their lives due to the storm, including 33 following a plane crash near Quy Nhơn.[23][24] In the wake of the storm, the South Vietnamese government provided the hardest hit areas with relief funds and supplies.[24]

The strongest typhoon of the season, Irma, reached a peak intensity of 180 mph (290 km/h) on November 11. It remained at sea, affecting only shipping and causing minor damage to the islands of the West Pacific. At the time, the typhoon held the record for the fastest intensification in a 24‑hour period, deepening from 980 mbar to 884 mbar but it was beaten by Typhoon Forrest of 1983.[25]
