1964 Pacific typhoon season
Encyclopedia
The 1964 Pacific typhoon season has no official bounds; it ran year-round in 1964, 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 1964 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.
The 1964 Pacific typhoon season was the most active season in recorded history with 39 storms. Notable storms include 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 Hong Kong's worst named typhoon in history.
Five typhoons performed cyclonic loops this season; only two or three happen on average yearly. Kathy did a rare move by executing a second minor loop while undergoing the first loop. Another unusual phenomenon that occurred during the 1964 season was rapid degeneration of typhoons. Notable ones include Alice, Elsie and Cora which degenerated into tropical lows within hours. No apparent reason has been found to this rapid degeneration event.
(JTWC) on May 9 near Woleai Atol. Tracking steadily west-northwestward, the system gradually organized. Early on May 14, the system had become sufficiently organized for the JTWC to classify it as a tropical depression. Over the following four days, the depression moved erratically, executing two loops, and fluctuated between tropical storm and tropical depression status. During the morning of May 15, the system had intensified into a tropical storm and was given the name Tess. The developing storm eventually retained a east-northeastward track by May 18. The following day, reconnaissance aircraft recording data on the storm discovered that it had developed two eyes
. The first and innermost eye was unusually small, measuring 6 mi (9.7 km) across while the second was asymmetrical, measuring roughly 14 mi (22.5 km) by 9 mi (14.5 km). Upon finding this feature, Tess was estimated to have attained typhoon status. Gradual intensification took place over the following few days as the storm turned more northeasterly. On May 22, Tess attained its peak intensity with winds of 155 km/h (100 mph) and a barometric pressure of 965 mbar
(hPa
). However, by this point the typhoon was moving over higher latitudes and into a less favorable environment. The following day, Tess had significantly weakened to a tropical storm and the center of the storm became exposed. Later on May 23 the typhoon became extratropical
as it moved over the north Pacific.
on May 16 and moved to the northeast dissipating within 18 hours. Only four advisories were released on Tropical Depression 2W.
. The depression became Tropical Storm Viola the same day, and then Typhoon Viola on the 27th. Viola peaked at 80 mph (129 km/h) winds with a pressure of 980 mbar. The typhoon made landfall in Hong Kong on May 28, dissipating soon after.
Striking near Hong Kong as a tropical storm, Viola brought heavy rains and strong winds to the region, ending a two year drought
. Business was nearly brought to a standstill as roads were blocked off and transportation suspended. Several fishing vessels ran aground and 28 people were injured. Additionally, thousands of people living in "junk" houses were left homeless.
A total of 100 people were killed and over 500,000 were left homeless throughout the Philippines due to the typhoon. Thousands of poorly constructed homes were destroyed and the capital city of Manila
, home to over 2.5 million people, was paralyzed by the storm. The entire city suffered a blackout from Winnie, and officials reported that it would take days to begin restoring power. High winds downed large billboards and tore roofs off many structures as well as uprooting trees. Thousands of residents were left homeless by the storm. Torrential rains triggered widespread flooding throughout the affected region, isolating several communities. Sea and airports were closed for several days due to the system. Damage from the storm were estimated to be in the tens of millions, making Winnie the worst storm to strike the country in roughly 30 years.
on the 27th and also reached its peak intensity of 75 mph (121 km/h) with a pressure of 990 mbar. Alice was absorbed by Typhoon Winnie on June 28 near Yap
.
on July 2. The depression moved west and strengthened into a storm the same day. Betty moved west, peaking at 125 mph (201 km/h) winds the next day. After passing Shanghai, China on July 6, rapid weakening occurred and Betty dissipated.
as a tropical storm on July 10. Cora dissipated the same day over water.
. Elsie weakened and dissipated over water on the 18th.
, without making landfall.
In Okinawa, rough seas from the storm led to the collision of two U.S. Navy vessels and another to run aground. Damage sustained by the ships was reported to be minor. In South Korea, two fishermen drowned and a third was listed as missing after the typhoon brushed northern portions of the country. Offshore, 15 fishing boats were destroyed.
. Strengthening occurred and 13W was given the name Grace. Grace strengthened into a 60 mph (97 km/h) tropical storm. Grace made a curve on the 29th and dissipated the next day. Strengthening re-occurred and Grace reached tropical storm status on August 3. Grace finally dissipated the next day. (see below)
. The depression strengthened quickly, reaching tropical storm status that same day and receiving the name Helen. Rapid strengthening occurred which caused Helen to become a typhoon on the 29th. By July 30, Helen was a Category 4 super typhoon just south of Iwo Jima
. That same day, Helen just passed by Iwo Jima. Rapid weakening occurred and Helen made landfall in China as a 50 mph (80 km/h) tropical storm on August 3. Helen dissipated over land the same day.
at that intensity that night. After weakening over the island, Ida turned to the northwest and hit southeastern China near Hong Kong on August 8 as a 100 mph (160 km/h) typhoon. The storm killed 75 people, and caused moderate to heavy damage on its path.
.
on August 12. Strengthening occurred slowly, reaching tropical storm status, receiving the name Lorna and dissipating the next day at a 40 mph (64 km/h) tropical storm peak.
on the 17th. Marie made landfall in Japan on the 18th and was absorbed by Typhoon Kathy the same day.

on September 2. The depression moved north and dissipated on September 3, without making landfall.
as a 30 mph (48 km/h) depression. 27W quickly strengthened and was given the name Sally the same day. Rapid strengthening occurred as Sally moved west, reaching typhoon status by September 4, super typhoon status by the 6th and its peak intensity of 894 mbar with 195 mph (314 km/h) winds, becoming the strongest typhoon of the season on the 7th. Sally made landfall in Philippines
on the 9th as a Category 4 typhoon. Weakening occurred and made landfall in China as a 115 mph (185 km/h) typhoon on the 10th, dissipating over land the same day.

on the 23rd. The depression dissipated on October 24.
late on October 23. The depression gained strength and was given the name Hope within six hours. Strengthening occurred slowly and Hope reached typhoon intensity on October 27. The storm peaked at 85 mph (137 km/h) winds on the 28th near Chichi Jima. The storm weakened over water and became extratropical on the 30th near Japan.
Typhoon Iris brought significant rainfall to parts of Vietnam, resulting in significant flooding. However, a few days after Iris moved through the country, Typhoon Joan worsened the situation significatnly.
.
Due to the rapid succession of Typhoons Iris and Joan, widespread flooding and catastrophic flooding was reported across central 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. As a result of the catastrophic floods, over 7,000 people were killed in the country.

or PAGASA. This can often result in the same storm having two names.
The 1964 Pacific typhoon season was the most active season in recorded history with 39 storms. Notable storms include 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 Hong Kong's worst named typhoon in history.
Seasonal activity
52 numbered tropical waves formed this year in the Western Pacific, of which 39 became tropical storms. 26 storms reached typhoon intensity, of which 7 reached super typhoon strength. The season's 39 tropical storms is the most recorded tropical storms to form in the basin. The South China Sea saw higher than normal activity in 1964 – between the years 1959-1963, the average was 3.2 typhoons to travel the area, compared to the 10 typhoons in the 1964 season. Two of the super typhoons, Sally and Opal, set seasonal records - Sally was strongest storm of the season, reaching a pressure of 894 mbar while Opal was the largest system of the season.Five typhoons performed cyclonic loops this season; only two or three happen on average yearly. Kathy did a rare move by executing a second minor loop while undergoing the first loop. Another unusual phenomenon that occurred during the 1964 season was rapid degeneration of typhoons. Notable ones include Alice, Elsie and Cora which degenerated into tropical lows within hours. No apparent reason has been found to this rapid degeneration event.

(JTWC) on May 9 near Woleai Atol. Tracking steadily west-northwestward, the system gradually organized. Early on May 14, the system had become sufficiently organized for the JTWC to classify it as a tropical depression. Over the following four days, the depression moved erratically, executing two loops, and fluctuated between tropical storm and tropical depression status. During the morning of May 15, the system had intensified into a tropical storm and was given the name Tess. The developing storm eventually retained a east-northeastward track by May 18. The following day, reconnaissance aircraft recording data on the storm discovered that it had developed two eyes
Eye (cyclone)

. The first and innermost eye was unusually small, measuring 6 mi (9.7 km) across while the second was asymmetrical, measuring roughly 14 mi (22.5 km) by 9 mi (14.5 km). Upon finding this feature, Tess was estimated to have attained typhoon status. Gradual intensification took place over the following few days as the storm turned more northeasterly. On May 22, Tess attained its peak intensity with winds of 155 km/h (100 mph) and a barometric pressure of 965 mbar

Tropical Depression 42W
Tropical Depression 42W formed on October 30 and lasted for several days over water. 42W dissipated on November 4, never reaching tropical storm status. The location of this depression is unknown.Typhoon 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 994 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 18 mi (29 km) wide eye. Several hours later, the storm made landfall in central Vietnam at this strength. Rapid weakening took place shortly thereafter, with the storm dissipating late on November 4 over the high terrain of Vietnam.Typhoon Iris brought significant rainfall to parts of Vietnam, resulting in significant flooding. However, a few days after Iris moved through the country, Typhoon Joan worsened the situation significatnly.
Typhoon Joan
Similar to the formation of Typhoon Iris, Typhoon 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 999 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. Typhoon 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 LaosLaos

or PAGASA. This can often result in the same storm having two names.
The 1964 Pacific typhoon season was the most active season in recorded history with 39 storms. Notable storms include 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 Hong Kong's worst named typhoon in history.
Seasonal activity
52 numbered tropical waves formed this year in the Western Pacific, of which 39 became tropical storms. 26 storms reached typhoon intensity, of which 7 reached super typhoon strength. The season's 39 tropical storms is the most recorded tropical storms to form in the basin. The South China Sea saw higher than normal activity in 1964 – between the years 1959-1963, the average was 3.2 typhoons to travel the area, compared to the 10 typhoons in the 1964 season. Two of the super typhoons, Sally and Opal, set seasonal records - Sally was strongest storm of the season, reaching a pressure of 894 mbar while Opal was the largest system of the season.Five typhoons performed cyclonic loops this season; only two or three happen on average yearly. Kathy did a rare move by executing a second minor loop while undergoing the first loop. Another unusual phenomenon that occurred during the 1964 season was rapid degeneration of typhoons. Notable ones include Alice, Elsie and Cora which degenerated into tropical lows within hours. No apparent reason has been found to this rapid degeneration event.

(JTWC) on May 9 near Woleai Atol. Tracking steadily west-northwestward, the system gradually organized. Early on May 14, the system had become sufficiently organized for the JTWC to classify it as a tropical depression. Over the following four days, the depression moved erratically, executing two loops, and fluctuated between tropical storm and tropical depression status. During the morning of May 15, the system had intensified into a tropical storm and was given the name Tess. The developing storm eventually retained a east-northeastward track by May 18. The following day, reconnaissance aircraft recording data on the storm discovered that it had developed two eyes
Eye (cyclone)

. The first and innermost eye was unusually small, measuring 6 mi (9.7 km) across while the second was asymmetrical, measuring roughly 14 mi (22.5 km) by 9 mi (14.5 km). Upon finding this feature, Tess was estimated to have attained typhoon status. Gradual intensification took place over the following few days as the storm turned more northeasterly. On May 22, Tess attained its peak intensity with winds of 155 km/h (100 mph) and a barometric pressure of 965 mbar

Tropical Depression 42W
Tropical Depression 42W formed on October 30 and lasted for several days over water. 42W dissipated on November 4, never reaching tropical storm status. The location of this depression is unknown.Typhoon 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 994 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 18 mi (29 km) wide eye. Several hours later, the storm made landfall in central Vietnam at this strength. Rapid weakening took place shortly thereafter, with the storm dissipating late on November 4 over the high terrain of Vietnam.Typhoon Iris brought significant rainfall to parts of Vietnam, resulting in significant flooding. However, a few days after Iris moved through the country, Typhoon Joan worsened the situation significatnly.
Typhoon Joan
Similar to the formation of Typhoon Iris, Typhoon 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 999 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. Typhoon Joan made landfall in nearly the same location as Typhoon Iris in central Vietnam before rapidly weakening over land.

or PAGASA. This can often result in the same storm having two names.
The 1964 Pacific typhoon season was the most active season in recorded history with 39 storms. Notable storms include 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 Hong Kong's worst named typhoon in history.
Seasonal activity
52 numbered tropical waves formed this year in the Western Pacific, of which 39 became tropical storms. 26 storms reached typhoon intensity, of which 7 reached super typhoon strength. The season's 39 tropical storms is the most recorded tropical storms to form in the basin. The South China Sea saw higher than normal activity in 1964 – between the years 1959-1963, the average was 3.2 typhoons to travel the area, compared to the 10 typhoons in the 1964 season. Two of the super typhoons, Sally and Opal, set seasonal records - Sally was strongest storm of the season, reaching a pressure of 894 mbar while Opal was the largest system of the season.Five typhoons performed cyclonic loops this season; only two or three happen on average yearly. Kathy did a rare move by executing a second minor loop while undergoing the first loop. Another unusual phenomenon that occurred during the 1964 season was rapid degeneration of typhoons. Notable ones include Alice, Elsie and Cora which degenerated into tropical lows within hours. No apparent reason has been found to this rapid degeneration event.

(JTWC) on May 9 near Woleai Atol. Tracking steadily west-northwestward, the system gradually organized. Early on May 14, the system had become sufficiently organized for the JTWC to classify it as a tropical depression. Over the following four days, the depression moved erratically, executing two loops, and fluctuated between tropical storm and tropical depression status. During the morning of May 15, the system had intensified into a tropical storm and was given the name Tess. The developing storm eventually retained a east-northeastward track by May 18. The following day, reconnaissance aircraft recording data on the storm discovered that it had developed two eyes
Eye (cyclone)

. The first and innermost eye was unusually small, measuring 6 mi (9.7 km) across while the second was asymmetrical, measuring roughly 14 mi (22.5 km) by 9 mi (14.5 km). Upon finding this feature, Tess was estimated to have attained typhoon status. Gradual intensification took place over the following few days as the storm turned more northeasterly. On May 22, Tess attained its peak intensity with winds of 155 km/h (100 mph) and a barometric pressure of 965 mbar

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 994 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 18 mi (29 km) wide eye. Several hours later, the storm made landfall in central Vietnam at this strength. Rapid weakening took place shortly thereafter, with the storm dissipating late on November 4 over the high terrain of Vietnam.Typhoon Iris brought significant rainfall to parts of Vietnam, resulting in significant flooding. However, a few days after Iris moved through the country, Typhoon Joan worsened the situation significatnly.
