Notable storms include Typhoon Joan, which killed 7,000 people in Vietnam; Typhoon Louise, which killed 400 people in the Philippines, Typhoons Sally and Opal, which had some of the highest winds of any cyclone ever recorded at 195 mph, Typhoons Flossie and Betty, which both struck the city of Shanghai, China, and Typhoon Ruby, which hit Hong Kong as a powerful 140 mph Category 4 storm, killing over 700 and becoming the second worst typhoon to affect Hong Kong.

In September, tropical cyclone activity was high across the Northern Hemisphere in both the Atlantic and Pacific. Subtropical ridging in the Pacific was extended zonally throughout the month, resulting in strong easterly winds in the subtropical latitudes and providing conducive conditions for storm development. The extensive ridging also prevented most of September's storms from taking curved paths into the

. On July 6, it organized into a tropical depression southwest of Guam, prompting the JTWC to initiate warnings. Intensification was rapid upon developing, with Cora becoming a typhoon by the end of July 6. Two days later, Cora attained sustained winds of 260 km/h (160 mph) as it approached the central Philippines on a westward heading, according to the JTWC; this classified Cora as a super typhoon. The eye spanned 6 mi (9 km) across at this juncture. Two consecutive airborne reconnaissance missions into the storm estimated that winds near the surface were around 325 km/h (200 mph). However, this value was discordant with the 130 km/h (80 mph) winds occurring at

and southern Luzon on July 9, its forward motion slowed and its winds unexpectedly diminished and fell below the typhoon threshold. Storm warnings were issued in southeastern Luzon with Cora 100 km (60 mi) east of Samar, with forecasts projecting stormy conditions in the region and in other islands in the east-central Philippines. However, the cyclone's winds continued to lessen before the system reached the islands. By July 10, Cora had weakened to a tropical depression. It tracked across southeastern Luzon and dissipated in the South China Sea the next day.


Typhoon Doris (Isang)

The initial system that led to Typhoon Doris began between Pohnpei and Chuuk State on July 9. Tracking towards the west-northwest, it passed near Chuuk and became a tropical depression on July 11 while 480 km (300 mi) south of Guam. Doris became a tropical storm by 12:00 UTC that day as it began to track northwest across the Philippine Sea. Early on July 13, Doris strengthened into a typhoon while approximately 800 km (500 mi) east of Luzon. The next day, Doris attained one-minute sustained winds of 150 km/h (90 mph).

Elsie intensified on approach to the Philippines, with the JTWC assessing it as a typhoon on July 16. At 04:00 UTC the next day, an aerial reconnaissance mission into Elsie estimated that the storm's winds reached 185 km/h (115 mph). The JTWC determined that this was Elsie's peak intensity. Storm warnings were posted for Luzon on July 17 ahead of the storm's approach. The typhoon then weakened rapidly from this peak; upon its landfall on the eastern coast of southern Luzon on July 17, it was a 140-km/h (85 mph) typhoon, with its intensity lowering to tropical storm stauts over the island shortly afterwards. Rainy squalls associated with Elsie caused extensive flooding in Manila and the northern Philippines, inundating buildings and streets. Elsie continued to weaken after emerging into the South China Sea and dissipated on July 19.


Typhoon Flossie (Nitang)

The initial vortex that became Typhoon Flossie was detected east of Luzon on July 24, embedded within an area of low pressure. It moved towards the northeast across the Philippine Sea and became a tropical depression on July 25. It became a tropical storm the next day as it curved northwest, passing south of Okinawa and intensifying into a typhoon shortly afterwards in the East China Sea. On July 28, Flossie continued to curve towards the north, passing just offshore the eastern coast of China near

, which resulted in the development of a tropical disturbance south of Chuuk State on August 1. The disturbance became a tropical depression roughly (300 mi) southeast of Guam on August 2 and strengthened into a tropical storm later that day. Tracking towards the west-northwest, Ida reached typhoon intensity on August 4. According to the JTWC, Ida reached its peak intensity with maximum winds of 250 km/h (155 mph) and a central pressure of 925 hPa (mbar; 27.31 inHg). Between August 6–7, Ida moved across northern Luzon with these winds. The storm weakened over the island but restrengthened over the South China Sea on approach to Hong Kong. The center of the storm passed 65 km (40 mi) southwest of Hong Kong and made its final landfall on Guangdong Province China on August 8 as a typhoon with winds of 150 km/h (90 mph) as estimated by Royal Observatory Hong Kong. As it tracked farther inland, Ida weakened and later dissipated on August 12. Eleven deaths in Luzon were attributed to Ida according to data from the

Tropical Storm June (Toyang)

Tropical Storm June began south of Guam as a disturbance on August 9. Traveling west-northwest, it became a tropical depression by the time aircraft reconnaissance first reached the system on August 10. Later that day, June attained a tropical storm and reached its peak intensity with winds of 75 km/h (45 mph). The storm held this intensity for a day before weakening as it neared Luzon contrary to forecasts projecting June to become a typhoon. The JTWC issued their last warning on the system on August 11 and considered the system to have dissipated two days later when it was north of Luzon and east of

Tropical Storm Lorna

Lorna began west of the Mariana Islands on August 10 and took a northeastward path throughout its duration. Its precursor disturbance developed from a trough of low pressure and became a tropical depression by August 12; the next day, Lorna became a tropical storm, prompting JTWC warnings. According to the JTWC, Lorna's winds topped out at low-end tropical storm speeds, 65 km/h (40 mph), for less than a day before it began to weaken. Lorna dissipated on August 14 north of

in the upper troposphere over the Philippine Sea led to the environmental conditions that resulted in the formation of Typhoon Marie. The initial disturbance formed on August 12 and tracked towards the north and then curved east, becoming a tropical depression the next day. Marie intensified into a tropical storm by August 15 and then curved north as it interacted with nearby Typhoon Kathy. Two days later, it became a typhoon and subsequently reached its peak intensity with winds estimated by the JTWC at 130 km/h (80 mph) and a central pressure estimated by the JMA of 980 hPa (mbar; 28.94 inHg). The storm then weakened and curved towards the west; the JTWC determine Marie to have been absorbed by Typhoon Kathy approximately 240 km (150 mi) north of Okinawa on August 18. However, the CMA and JMA assessed Marie to have remained intact, continuing on a curved path towards the south and then east, bringing it around Okinawa as a tropical cyclone until its dissipation on August 20.

, an atmospheric feature that was farther north than average in mid-August 1964. Ship observations suggested that the system became a tropical depression August 17 and became a tropical storm a day later. Nancy maintained low-end tropical storm intensity at peak strength before being downgraded to a tropical depression the next day approximately 480 km (300 mi) northeast of Iowa Jima, after which it dissipated.


Tropical Storm Olga

Olga remained within the Gulf of Tonkin for the entirety of its existence, taking a southward trajectory. The CMA determined that the cyclone formed on August 21, and became a tropical storm by August 24. The JTWC assessed that Olga lasted more briefly, beginning as a tropical depression on August 23 and peaking as a tropical storm the next day with one-minute sustained winds of 85 km/h (50 mph). It maintained this intensity and remained quasi-stationary over the gulf. Olga weakened to a tropical depression on August 25 and degenerated into a non-circulating cluster of thunderstorms later that day.

Sally inflicted around $115,000 in damage in Guam, mostly to crops, after bringing gusts of 130 km/h (80 mph) to the island and unroofing homes and felling trees. The damage remained limited to the southern half of Guam where the storm struck; there were no casualties. Sally produced strong winds and heavy rains to the Philippines north of Manila, causing considerable damage. Over 10,000 people were evacuated out of vulnerable areas in Hong Kong as the storm was feared to strike with a severity comparable to Typhoon Ruby a week prior.

/ref> Gusts peaked at 154 km/h (96 mph) at Tate's Cairn and rainfall accumulations reached as high as , triggering landslides that killed nine people. However, Sally's impacts on the Crown territory were less than initially feared; much of Hong Kong's vulnerable agriculture was already badly damaged during Ruby's passage. The remnants of Sally led to the heaviest rainfall in the Seoul area in 22 years, producing 125–200 mm (5–8 in) of rain in the area on the morning of September 13. The resulting floods killed at least 211 people and injured 317 others.

satellite. The initial vortex that became Tilda formed by September 12 and organized into a tropical depression by September 13. Tilda's winds reached typhoon intensity on September 14. Its center passed over the Bataan Islands the same day before moving west into the South China Sea. According to the JTWC, Tilda's one-minute maximum sustained winds crested at 165 km/h (105 mph) before their speeds began to decrease. On September 16, the center of Tilda passed 95 km/h (60 mi) south of Hong Kong. Tilda's close pass of Hong Kong prompted the hoisting of storm signals to warn ships and small craft, with the Royal Observatory escalating its warnings to typhoon signal no. 3. The typhoon then became stationary for nearly two days over the South China Sea with its winds concurrently falling to tropical storm intensity according to the JTWC. Tilda's meandering path disrupted shipping and led to the Royal Observatory keeping storm signals active for a record 161 hours. On September 19, the JTWC determined that Tilda reintensified into a typhoon after the storm began to move west. The typhoon's one-minue sustained winds were estimated by the agency at 205 km/h (120 mph) on September 20 before weakening ensued. Tilda made landfall on the coast of

Typhoon Violet

The CMA determined that Violet formed in the South China Sea on September 12, while the JTWC assessed tropical cyclogenesis on the following day. The system quickly strengthened and reached tropical storm and later typhoon intensity on September 14. Violet's one-minute sustained winds topped out at 140 km/h (85 mph) just prior to moving ashore Vietnam. Violet made landfall on Vietnam on the morning of September 15. It weakened quickly over land with the JTWC issuing its last advisory on the system on September 15 and the CMA considering the system to have dissipated on September 16. The storm generated rainfall totals in excess of between September 14–17, punctuated by a maximum measured value of . Ninety percent of homes were destroyed in Quảng Bình Province according to early reports. U.S. Marine Corps helicopters were deployed to evacuate those affected by the storm in Tam Kỳ, Vietnam. Light damage was wrought to facilities associated with U.S. Marine Corps support operations in Vietnam.


Typhoon Wilda

According to data from the JMA, Wilda began as a tropical storm east-southeast of Guam on September 16, marked by a large mass of clouds and associated rainbands. The system tracked northwest over the Northern Mariana Islands and into the Philippine Sea two days later. The JTWC recognized the storm as a tropical cyclone on September 19 when it was located roughly 370 km (230 mi) northwest of

, and assessed Wilda to have strengthened into a typhoon later that day. An eye emerged on Nimbus satellite imagery on September 20, and on September 21, Wilda reached its peak intensity over the Philippine Sea with one-minute maximum sustained winds of 280 km/h (175 mph) as estimated by the JTWC and a minimum central pressure of 895 hPa (mbar; 26.43 inHg). Based on data from the JMA, this was tied for lowest central pressure of any typhoon in 1964, along with Typhoon Sally. Wilda slightly weakened following peak strength before curving northward and making landfall on Kagoshima on September 24; one-minute sustained winds three hours prior to landfall were estimated to be 185 km/h (100 mph). The storm passed over Shikoku and southern Honshu before emerging into the Sea of Japan and curving northeast. Wilda made a final landfall on the western coast of northern Honshu on September 25 as a tropical storm, thereafter departing Japan and quickly moving towards the central

Wilda was one of the strongest typhoons to ever strike Japan as measured by atmospheric pressure, reaching Cape Sata in Kagoshima with a central pressure of 940 hPa (mbar; 27.76 inHg). The typhoon caused 47 fatalities and 530 injuries in Japan. Over 70,000 homes were destroyed and nearly 45,000 were inundated by the typhoon across the country, leaving thousands of people homeless.

Tropical Storm Anita

Tropical Storm Anita formed just west of Luzon on September 23. It initially tracked towards the southwest and attained tropical storm intensity in the central South China Sea on September 25 according to data from the JTWC. Its intensity oscillated as curved west and neared central Vietnam, peaking in strength with winds of 95 km/h (60 mph) on September 26; these winds were inferred from maritime observations near the storm. The following day, Anita made landfall near Da Nang, Vietnam, and later weakened over land; the storm dissipated on September 28.


Tropical Storm Billie (Kayang)

Tropical Storm Billie began southwest of Guam on September 24. The JTWC detected the system based on surface observations the next day while the system was centered 480 km (300 mi) southwest of Guam. Billie reached tropical storm intensity on September 27 as it moved west. While the system may have degenerated into an open trough of low-pressure on September 28 amid strong easterly winds, it quickly reorganized and strengthened further before tracking across southern Luzon from Catanduanes to just south of Manila with winds of 85 km/h (50 mph). Bille emerged into the South China Sea thereafter, where its winds topped out at 110 km/h (70 mph). The center of the tropical storm passed south of Hainan on September 30 and made landfall on Vietnam on October 1. Billie had already begun to weaken on approach to land but diminished further once over Southeast Asia; the storm and its remnants continued tracking west into Myanmar before dissipating on October 3. Sixteen people were killed by floods triggered by Billie's rains in Camarines Sur. The torrents destroyed homes and left 10,000 families homeless. Flooding swept away a bridge along a railroad of the Philippine National Railways, causing a passenger car to derail; one person was injured. The Manila area also experienced widespread floods. Property damage from the tropical storm totaled US$3 million.


Typhoon Clara (Dorang)

Clara formed southwest of Guam on October 1 from a separating portion of a trough and initially moved towards the northwest. Weather observations near the storm at the time of its formation were sparse. The JTWC assessed the system to have reached tropical storm status on October 2. Continuing to intensify, Clara curved west over the central Philippine Sea on October 3 and strengthened into a typhoon the next day according to data from the JTWC. Clara's winds topped out at 150 km/h (90 mph) as it made landfall on the coast of Aurora (province), Aurora at Dilasac Bay on October 5. Warnings were raised for Clara across parts of eight Filipino provinces ahead of the storm's approach. Clara weakened over Luzon but remained a typhoon upon emerging into the South China Sea, where it eventually reattained one-minute sustained winds of 150 km/h (90 mph). Tracing a path similar to Tropical Storm Billie a week prior, the center of Clara passed south of Hainan on October 7. The storm weakened within the Gulf of Tonkin and struck Vietnam north of Đồng Hới on October 8 with one-minute sustained winds estimated at 85 km/h (45 mph) by the JTWC. The cyclone weakened inland and rapidly dissipated over Thailand on October 8.


Typhoon Dot (Enang)

Dot originated from the interaction of a trough of low-pressure and a tropical wave west of Pohnpei in early October. Aircraft reconnaissance first encountered the system on October 6, finding a developing tropical storm 160 km (100 mi) southwest of Yap. Dot traveled on a west-northwestward heading and curved gradually towards the northwest, becoming a typhoon on October 9. Dot then curved towards the west and made landfall on northern Luzon the following day with one-minute sustained winds of 130 km/h (80 mph). The storm continued to strengthen once it emerged into the South China Sea, and reached its peak intensity with one-minute sustained winds of approximately 165 km/h (105 mph) on October 11. Dot then curved slowly northward and moved ashore China just east of Hong Kong on October 13 at largely the same intensity. The storm then quickly weakened inland, transitioning into an extratropical cyclone on October 15 and curving northeast back into the Pacific before it was last noted off Japan on October 19. Dot was the fifth typhoon in 1964 to hit Hong Kong. Its proximity to the Crown colony led to the issuance of tropical cyclone signal no. 10 from the Royal Observatory and forced the suspension of public transportation and incoming flights. The Royal Observatory recorded of rain and gales for eight consecutive hours. At Tate's Cairn, a maximum wind gust of 220 km/h (137 mph) was measured. Numerous rain-triggered landslides destroyed homes and blocked roads, resulting in most of the casualties associated with the typhoon. The official death toll from the storm in Hong Kong enumerated 26 fatalities and 85 injuries with 10 unaccounted for, though press reports at the time indicated a higher death toll. Total property damage was estimated to be in the millions of U.S. dollars.


Tropical Depression Ellen

Tropical Depression 37W formed west of Kawalein on October 8, peaking at a 50 mph (80 km/h) tropical storm and was given the name ''Ellen''. Ellen dissipated on October 10 near Pohnpei, Ponape.


Tropical Storm Fran

Fran began its development northwest of the

around October 13. Aircraft reconnaissance reached the system on October 15, encountering as a westward-moving tropical storm. Fran then took a more northward heading, and only October 17 attained peak one-minute sustained winds of 95 km/h (60 mph) approximately 650 km (400 mi) west of Wake Island according to the JTWC. Thereafter, the storm began to take on extratropical characteristics, with its center of circulation enlarging and becoming irregular. Fran continued north before curving east after October 20, eventually transitioning into an extratropical system by October 21 and dissipating on October 23 over the open Pacific.


Tropical Storm Georgia (Grasing)

Tropical Storm Georgia was first observed as a tropical depression 360 km (225 mi) south-southwest of Guam on October 17. The nascent cyclone did not organize further, with aircraft reconnaissance unable to locate the storm's central vortex. However, the system became more pronounced on October 20 as it tracked towards the west-northwest, and became a tropical storm on October 21 near the Philippines. At around 06:00 UTC on October 21, Georgia made landfall on Luzon at Lamon Bay and passed north of Manila; one-minute sustained winds associated with the storm at the time were around 65 km/h (40 mph). It then crossed into the South China Sea where intensification continued as the Georgia's one-minute sustained winds reached 85 km/h (50 mph). The tropical storm passed south of Hainan and made landfall on Vietnam near Vinh on October 23, after which it dissipated.


Typhoon Hope (Hobing)

Typhoon Hope originated around October 21 near the island of Pohnpei, tracking west at tropical depression intensity for three days. On October 24, when it was west of Guam, the JTWC upgraded the system to tropical storm status based on aerial observations of the system. Hope continued to track west before curving north on October 25 towards an eventually northeastward track. On October 27, Hope became a typhoon northwest of the Bonin Islands as it accelerated northeast. This intensification was attributed to the instrusion of colder air into the typhoon's circulation, causing a surge of winds in the lower levels of the atmosphere during a relatively short timeframe. Though winds as high as 240 km/h (150 mph) were estimated by aircraft reconnaissance investigating the typhoon during this period, Hope's one-minute sustained winds in the JTWC's tracking data peaked at 140 km/h (85 mph). The typhoon gradually weakened thereafter, but continued to produce strong winds and waves 8.2 m (27 ft) high. On October 29, the storm weakened to tropical storm strength and later transitioned into an extratropical cyclone. The extratropical cyclone intensified on approach to the central

and later became part of a broader cyclonic system within the Bering Sea.


Tropical Storm Iris

On November 1, the JTWC began monitoring a tropical disturbance over the South China Sea, near the western Philippines. The following day, the system quickly organized as it moved in a general eastward direction. During the afternoon, the JTWC issued their first advisory on the system, immediately declaring it Tropical Storm Iris. After briefly taking a northeasterly track, Iris turned towards the southeast and reconnaissance planes recorded a developing eyewall. The following day, the a pressure of 1000 mbar (hPa) was recorded in the center of the storm; however, this reading was not taken at the storm's highest intensity. On November 4, Iris intensified into a minimal typhoon, attaining winds of 120 km/h (75 mph) and featured a circular wide eye. Several hours later, the storm made landfall in central South Vietnam at this strength. Rapid weakening took place shortly thereafter, with the storm dissipating late on November 4 over the high terrain of Vietnam. Tropical Storm Iris brought significant rainfall to parts of Vietnam, resulting in significant flooding. However, a few days after Iris moved through the country, Tropical Storm Joan worsened the situation significantly.


Tropical Storm Joan

The deadliest storm of the 1964 season, Tropical Storm Joan brought heavy flooding that killed 7,000 people in
Vietnam Vietnam or Viet Nam ( vi, Việt Nam, ), officially the Socialist Republic of Vietnam,., group="n" is a country in Southeast Asia, at the eastern edge of mainland Southeast Asia, with an area of and population of 96 million, making i ...
. Similar to the formation of Tropical Storm Iris, Tropical Storm Joan originated from a tropical disturbance over the western South China Sea on November 5. Tracking eastward, the system quickly organized and was immediately declared a tropical storm on November 6. Early the next day, a reconnaissance plane recorded a pressure of 1000 mbar (hPa), the lowest in relation to Joan; however, this was measured while the system was a minimal tropical storm. Continued development took place over the following day as a well-defined wall cloud developed within the system. Joan attained typhoon intensity during the afternoon of November 8 and reached its peak intensity with winds of 130 km/h (80 mph) shortly thereafter. Tropical Storm Joan made landfall in nearly the same location as Typhoon Iris in central Vietnam before rapidly weakening over land. The system eventually weakened to a tropical depression on November 9 before dissipating over

. Due to the rapid succession of tropical storms Iris and Joan, widespread flooding and catastrophic flooding was reported across central South Vietnam. Roughly 90% of structures in three provinces were damaged by the storms and nearly one million were estimated to have been left homeless. Military operations during the Vietnam War were suspended by the typhoons.


Typhoon Kate

A tropical wave was spotted off

on November 12. The wave became Tropical Depression ''45W'' on the 13th. The depression quickly strengthened into Tropical Storm ''Kate'' the same day. Kate made a curve to the west as a 60 mph (97 km/h) tropical storm. Kate strengthened into a typhoon on the 15th and a peak at 90 mph (145 km/h) winds the next day. Kate made landfall over South Vietnam on the 17th, dissipating over land.


Typhoon Louise–Marge (Ining–Liling)

Louise–Marge began as a cyclonic vortex associated with a tropical wave near Yap State on November 12. Two days later, the system became a tropical depression, and reached tropical storm intensity on November 15. This initial tropical cyclone was named ''Louise'' by the JTWC. Louise became a typhoon the next day and passed south of Angaur with one-minute sustained winds estimated at approximately 185 km/h (100 mph). Louise continued to intensify after passing the island, and attained its peak intensity on November 18 with one-minute sustained winds of 305 km/h (190 mph) and a central air pressure of 915 hPa (mbar; 27.09 inHg). Louise was unusually close to the equator for a storm of its intensity; persisting at a strength equivalent to a Category 5 hurricane on the Saffir–Simpson scale at 7.3°N, closer to the equator than any other Northern Hemisphere tropical cyclone of such intensity. On November 19, Louise made landfall on Lanuza, Surigao del Sur, Lanzua Bay in Surigao del Sur, Surigao del Sur, Philippines, with winds of approximately 260 km/h (160 mph). Meteorological agencies disagree on the evolution of Louise after landfall, with the JTWC and JMA determining that it dissipated on November 21. The two agencies determined that a second distinct tropical cyclone east of the Philippines, named ''Marge'' by the JTWC, formed concurrently. The CMA lists the Marge as a continuation of Louise. This storm tracked across Luzon and eventually dissipated in the South China Sea by November 26. Anguar and Peleliu suffered widespread damage with the toll ranging between US$50,000–US$500,000. On Peleliu, 97 percent of structures were destroyed, while 90 percent of homes on Anguar were destroyed. The loss of homes on the two islands displaced 178 families. One person was killed and four people were injured. The U.S. Weather Bureau called Louise—Marge one of the most destructive storms ever documented in the central Philippines. At least 576 people were killed, though the Philippine Red Cross recorded 631 fatalities, along with 157 missing people and 376,235 people displaced by the typhoon. Nineteen Philippine provinces were impacted by the storm. Widespread destruction occurred in Surigao City, where the storm killed 312 people and caused US$12.5 million in damage.; Several ships sank during the storm, contributing in part to the death toll. A state of calamity (Philippines), state of calamity was declared for Surigao del Norte, prompting an intense relief effort amid an ongoing cholera epidemic and unrelated flooding. In June 1966, the Congress of the Philippines authorized Philippine Peso, ₱3.4 million to be distributed annually through fiscal year 1969-70 for the province and its municipalities.


Tropical Storm Nora (Moning)

Nora began within the Sulu Sea near the Cagayan Islands sometime around November 26–27, and became a tropical storm shortly after it was first detected. The storm tracked towards the northeast and reached its peak strength on November 27 with one-minute sustained winds estimated by the JTWC at 100 km/h (65 mph). Nora then curved northwest before moving ashore Mindoro in the Philippines on November 28. The storm then weakened to a tropical depression and strengthened no further, though data from tracking agencies disagree on Nora's demise, with the HKO and JTWC analyzing the storm to have dissipated in the direction of the South China Sea while the CMA and JMA indicating that the system continued northeast across the Philippines before dissipating over the Philippine Sea. Rough waters kicked up by the storm led to the sinking of a cargo ship near Zamboanga City, causing the presumed drownings of 18 people; another 37 crewmembers were rescued.


Typhoon Opal (Naning)

Opal formed from a tropical wave moving through the Caroline Islands in early December, with an initial wind circulation developing by December 8. The newly formed system organized quickly; by the time a reconnaissance aircraft encountered the system 160 km (100 mi) southwest of Chuuk Lagoon on December 9, Opal was already a typhoon with an eye spanning 40 km (25 mi) across. Between December 10–12, Opal moved between

and Palau, passing 65 km (40 mi) north of Kayangel with one-minute sustained winds of 260 km/h (160 mph). On December 12, Opal reached its peak intensity with one-minute sustained winds of 315 km/h (195 mph) and a central pressure of 895 hPa (26.43 inHg). Data from the JTWC indicated that Opal's winds, along with Sally earlier in the year, were the highest of any typhoon in 1964. Opal also had the largest wind circulation of any typhoon in 1964, with a total span of 2,100 km (1,300 mi). On December 14, the typhoon passed north of Cataduanes and Polillo Island and its winds began to lessen. Later that day, Opal made landfall on central Luzon with one-minute sustained winds of 140 km/h (85 mph). The typhoon weakened further as it moved over Luzon. Its center then executed a small counterclockwise loop over western Luzon before curving north and briefly emerging into the Lingayen Gulf as a tropical storm. Opal crossed northwestern Luzon and the Babuyan Islands on December 16 and later became extratropical near Okinawa on December 17; this phase of Opal's development dissipated the next day. Opal inflicted minor damage to a few homes in Palau, where winds reached an estimated 140 km/h (85 mph). Tent homes in Angaur and Peleliu were inundated by storm surge. The Philippine Weather Bureau initially issued storm warnings for the eastern Visayas and Mindanao on December 13 in anticipation of Opal; these warnings were later extended to southern and central Luzon. Philippine Airlines cancelled all flights scheduled for the afternoon of December 14 and the U.S. military moved its Luzon-based aircraft to safety.

closed and railways were brought to a standstill. Some schools and offices in Manila were forced to close due to Opal's rains. The total cost of damage caused by Opal in the Philippines was estimated at US$25 million. Two people were killed and another three were injured in Virac, Catanduanes, after their house was razed by a landslide caused by torrential rainfall. Opal caused significant property damage in Luzon and disrupted communications. Rice crops were damaged by heavy rainfall, and together with coconut crops, sustained losses estimated in the millions of U.S. dollars. These crop losses were most severe in central and southeast Luzon. A washout led to the derailing of eight coaches on passenger train carrying 1,500 passengers in Quezon. Another train with 400–500 passengers collided with a goods wagon blown onto the tracks by Opal's winds, though no injuries were reported. A freighter was driven ashore by the typhoon at Jose Panganiban, Camarines Norte, Jose Panganiban. In total, 26 people were killed and thousands of others were left homeless in the wake of Opal in the Philippines. The Philippine government designated 54 provinces and cities disaster areas. Rough seas from Opal off Okinawa swept two people off a ship stranded on a reef during a rescue operation, leading to their deaths.


Storm names


International

During the season 39 named tropical cyclones developed in the Western Pacific according to the JTWC and named by the agency when it was determined that they had become tropical storms. The names were drawn sequentially from a set of four alphabetical naming lists and were all feminine. After the season JTWC announced that the name ''Tilda'' would be removed from the list and the name selected to replace it was ''Therese'' which was first used in the 1967 Pacific typhoon season, 1967 season.

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. 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.). Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 6 of which are published each year before the season starts (in this case, all of them are used up and more auxiliary names are given). All of the storm names here are used for the first time (and only, in case of Dading). The names not retired from this list will be used again in the 1968 Pacific typhoon season, 1968 season. After the season, PAGASA announced that the name ''Dading'' would be struck from their naming lists due to its impacts and was replaced by ''Didang'' which was first used during the 1968 Pacific typhoon season, 1968 season, this name was later retired by the Agency during the 1976 Pacific typhoon season and replaced with ''Ditang'' which was first used during the 1980 Pacific typhoon season, 1980 season.
