The PAGASA warning system issues a storm signal no higher than Number 2. The depression quickly strengthened into Tropical Storm Kate the same day. Definition. [12] Streets in Manila were flooded to waist-height from heavy rains and hgh waves. The names not retired from this list will be used again in the 1968 season. The extensive ridging also prevented most of September's storms from taking curved paths into the westerlies; while approximately half of September typhoons curve into the westerlies on average, only one typhoon, Wilda, took such a trajectory in 1964. [6]:134 The disturbance became a tropical depression roughly (300mi) southeast of Guam on August2 and strengthened into a tropical storm later that day. PMC [13] 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. The cyclone weakened inland and rapidly dissipated over Thailand on October8. [167]:136 Precipitation totals were enhanced by orographic effects on southwest-facing slopes in southwestern Laos near the Thailand border. 2017;43:184194. [62] On June27, Alice made its closest approach to Guam, passing 95km (60mi) southwest of the island. It then recurved creating a loop and finally exited to South China Sea. So, The intensity and size represents different aspect of a typhoon. Two days later, Kathy's winds were estimated by the JTWC to be around 215km/h (130mph) near Minamidaitjima. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Bethesda, MD 20894, Web Policies [70][71] By July10, Cora had weakened to a tropical depression. The typhoon still dumped more rains and threw its tempest by early morning of December 11 at Northern Palawan. Its intense cyclonic eddy circulations often cause serious damage to coastal areas. [18] The first half of June marked a reversal of this pattern as a large area of low pressure became established over the mid-Pacific. By comparison, the Ohio subs, America's largest, displaces a 'mere' 19,000 tons, slightly over a third of the Typhoon's mass. [213], The deadliest storm of the 1964 season, Tropical Storm Joan brought heavy flooding that killed 7,000 people in Vietnam. [79] A third ship, the USS Weiss, ran aground at Buckner Bay after the storm separated the ship from its anchorage. Opal also had the largest wind circulation of any typhoon in 1964, with a total span of 2,100km (1,300mi). [89] In the city of Kagoshima, 16homes were razed and 36others were damaged. 2 - tropical . Data classification is a method for defining and categorizing files and other critical business information. [117] During this period, an airplane investigating the storm identified multiple wind circulations at the center of Kathy and the storm's clouds were asymmetric. Typhoon is determined by intensity and size. [19] July1964 featured more tropical cyclones than any other July on record, though this was superseded by the 1971 Pacific typhoon season. The nascent cyclone did not organize further, with aircraft reconnaissance unable to locate the storm's central vortex. [12][160] The resulting floods killed at least 211people and injured 317others. [113] Four people were killed after a mudslide pushed into a refugee camp and razed three houses Kwun Tong, with the 20,000m3 (700,000ft3) surge of mud placing areas under 7.5m (25ft) of debris. Strong typhoon: the maximum average wind speed near the bottom center is 41.5-50.9 m/s, or level 14 to 15. In this report, we propose a deep learning technique for high-accuracy estimation of the intensity class of a typhoon from a single satellite image, by incorporating meteorological domain knowledge. A new framework of deep learning neural network, Graph Convolutional-Long Short-Term Memory Network (GC-LSTM), is proposed, which is based on the data of satellite cloud . [134][25][24][6]:155 Two days later, it became a typhoon and subsequently reached its peak intensity with winds estimated by the JTWC at 130km/h (80mph) and a central pressure estimated by the JMA of 980hPa (mbar; 28.94inHg). [87][12]:75 The nexr day, the center of Helen moved over Jeju-do with winds of 150km/h (90mph) as estimated by the JTWC. [218] This initial tropical cyclone was named Louise by the JTWC. The 1964 Pacific typhoon season was the most active tropical cyclone season recorded globally, with a total of 40 tropical storms forming. The system continued to decay as it moved north and dissipated over the Yellow Sea on July17. [240] Data from the JTWC indicated that Opal's winds, along with Sally earlier in the year, were the highest of any typhoon in 1964. View the histogram for maximum wind. The next day, the disturbance developed into a tropical depression and gradually took on a more westward course. The system eventually weakened to a tropical depression on November9 before dissipating over Laos.[215]. Timeline of tropical activity in 1964 Pacific typhoon season, The 1964typhoon season was the most active Pacific typhoon season on record. 10. 9 at the height of the storm. [218] This storm tracked across Luzon and eventually dissipated in the South China Sea by November26. [46][12]:74 The air traffic control tower at Manila International Airport was put out of commission following wind damage. The Observatory does not anticipate that the introduction of typhoon classification will affect the existing contingency plans for tropical cyclones.. To point out the important characteristics of the data at a flash. Super typhoons are the equivalent of a at least a high-end Category 4 hurricane on the . [173][12]:77 The storm was last identified on September27. [30][148] On September7, Sally reached its peak intensity over the Philippine Sea with winds of 315km/h (195mph) and a central pressure of 895hPa (mbar; 26.43inHg). [62][6]:92 Tracking towards the west-northwest, Alice's intensity fluctuated in its initial stages. Rev. Ferry services were suspended in the territory. [12]:77[167]:76 Storm surge at Lng C reached 1.7m (5.6ft). [22] Nancy maintained low-end tropical storm intensity at peak strength before being downgraded to a tropical depression the next day approximately 480km (300mi) northeast of Iowa Jima, after which it dissipated. Tropical cyclone classification varies between Typhoon Committee Members. The super typhoon had gusts of as strong as 315 km/h. [6] eCollection 2022. However, a few days after Iris moved through the country, Tropical Storm Joan worsened the situation significantly. [34], The Royal Observatory Hong Kong issued typhoon signal No. Performance comparison results of different, Performance comparison results of different models (Note: M1 is the ANN model, M2, Feature extraction effect of different number of convolution kernels (Note: Q1 (1 . [62] According to the agency, Alice was the smallest typhoon of 1964, with a radius of 320km (200mi). An analysis of the historical tropical cyclone record for the West Pacific published in the Monthly Weather Review concluded that there was "sufficient evidence" that the winds in storms like Cora were "likely overestimated. The storm then began to take an erratic path that continued for the next three days. tropical cyclone, also called typhoon or hurricane, an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain. -, Chen L.L., Tseng C.H., Shih Y.H. [53] Thousands of trees were uprooted and basic utilities were brought down by the storm;[56] Manila was without power or water for at least 36hours. Winnie reached tropical storm strength on June27 and then typhoon strength on June28 as it rapidly intensified en route to southern Luzon. The area is very likely to be hit directly by the eye of the typhoon. It initially tracked towards the southwest and attained tropical storm intensity in the central South China Sea on September25 according to data from the JTWC. [107], In Hong Kong, the Royal Observatory advised ships to seek shelter in port and issued typhoon signal no. [62][12]:75, The disturbance that led to Typhoon Betty was first detected in the Philippine Sea on July1 by the JTWC, having developed from a segment of a polar trough within an area of conducive winds in the upper-troposphere. Stud. Later that day, Opal made landfall on central Luzon with one-minute sustained winds of 140km/h (85mph). [139][12][6], Ruby was the first of two typhoons in 1964 for which the Royal Observatory in Hong Kong raised tropical cyclone signal no. [6]:96 The next day, the disturbance quickly developed into a tropical cyclone and strengthened into a typhoon by the end of July2. As the typhoon exited it slowed down and remained quasi-stationary for 2 days at the Spratly Islands dumping heavy rains at Northern Palawan. [6]:129 Helen moved across the northern Ryukyu Islands and southern Kyushu on August1 and entered the Yellow Sea as a weakened typhoon. [124] Kathy's effects flooded almost 1,700homes and destroyed 8others in Amami shima; winds there reached 138km/h (86mph). The typhoon track classification using tri-plots and Markov chain. [10] Ten of the year's tropical cyclonesGrace, Helen, Nancy, Pamela, Ruby, Fran, Georgia, Iris, Kate, Louise, and Opalwere first detected using meteorological satellites. It had 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. [142] The strong winds and heavy rain caused widespread damage in Hong Kong, destroying thousands of homes and damaging thousands of others. In extreme cases . [164] Tilda made landfall on the coast of Vietnam on September22 roughly 95km (60mi) northwest of Hu, Vietnam, and 200km (125mi) north of where Typhoon Violet struck a week prior. A typhoon cyclone, often known as a tropical cyclone or hurricane, is a powerful circular storm that forms over warm tropical waters and is distinguished by low air pressure, strong winds, and heavy rain. The COVID-19 pandemic continues to bring up various topics discussed or debated on social media. [6]:47 It rapidly weakened after reaching its peak strength. [117][12]:76, According to the publication Climatological Data, Kathy caused at least 13deaths and "numerous" injuries, with landslides and flooding being the principal cause of the casualties; as much as 700mm (28in) of rain was documented in the mountainous regions of Kyushu, though cities averaged 100m (4in) in rainfall accumulations. [173] The storm passed over Shikoku and southern Honshu before emerging into the Sea of Japan and curving northeast. 91730304/National Natural Science Foundation of China, Uson M.A.M. It weakened as it curved north towards the southern Ryukyu Islands, becoming a tropical storm on July14 and then a tropical depression on July15 while passing near Tarama, Okinawa. [13] A record gust of 211km/h (131mph) was measured in Taipa, Macau. [249][250] Opal caused significant property damage in Luzon and disrupted communications. [231][235][236] In June1966, the Congress of the Philippines authorized 3.4million to be distributed annually through fiscal year 1969-70 for the province and its municipalities. TYPHOON (TY) - a tropical cyclone with maximum wind speed of 118 to 220 kph. Eng. Early the next day, a reconnaissance plane recorded a pressure of 1000mbar (hPa), the lowest in relation to Joan; however, this was measured while the system was a minimal tropical storm. [29][12]:74 On May19, a reconnaissance flight investigating Tess observed two eyes: the first and innermost eye measured 9.7km (6mi) across while the second was asymmetrical, with axes roughly 23km (14mi) and 14km (9mi) across. Its intense cyclonic eddy circulations often cause serious damage to coastal areas. Int. [12]:78[251] Rice crops were damaged by heavy rainfall, and together with coconut crops, sustained losses estimated in the millions of U.S. The Typhoon class was developed under Project 941 as the Russian ''Akula'' class (), meaning shark. [154][155][156][157] Gusts peaked at 154km/h (96mph) at Tate's Cairn and rainfall accumulations reached as high as 354.4mm (13.95in), triggering landslides that killed nine people. Bille emerged into the South China Sea thereafter, where its winds topped out at 110km/h (70mph). [11], The active typhoon season was also impactful. Feature extraction result of some convolution kernels. [66], As Cora neared northern Samar and southern Luzon on July9, its forward motion slowed and its winds unexpectedly diminished and fell below the typhoon threshold. [64] There, sustained winds reached 138km/h (86mph), punctuated by a maximum gust of 201km/h (125mph). [27] The strong substropical ridging continued into October, leading to similar storm paths. Please add explanation of subfigures in caption. It then transitioned into an extratropical cyclone on July7 and dissipated over open waters just off the coast of northwestern South Korea. [73], The initial vortex that became Typhoon Flossie was detected east of Luzon on July24,[6]:121 embedded within an area of low pressure. [6]:72 On May14, it organized further into a tropical depression and took an erratic track over the next four days, including a looping course. The primary objectives of data classification are: To consolidate the volume of data in such a way that similarities and differences can be quickly understood. The Manila area also experienced widespread floods. sharing sensitive information, make sure youre on a federal Flossie reached its peak strength during this time with winds of 150km/h (90mph). When underwater, the Typhoon-class displaces 48,000 tons. Its center passed over the Bataan Islands the same day before moving west into the South China Sea. The first of the six members of the class to be commissioned was Dmitry Donskoy (TK 208) in 1981, followed by TK 202 in 1983, Simbirsk (TK 12) in 1984, TK 13 in . [164] On September16, the center of Tilda passed 95km/h (60mi) south of Hong Kong. [253] The Philippine government designated 54provinces and cities disaster areas. [169]:159, According to data from the JMA, Wilda began as a tropical storm east-southeast of Guam on September16, marked by a large mass of clouds and associated rainbands. [34] These winds diminished to 110km/h (70mph)just under typhoon intensityas Viola made landfall approximately 160km (100mi) west of Hong Kong at 03:00UTC on May28. The site is secure. [118][119] The typhoon's winds peaked at 165km/h (105mph) on August14 before tapering as the storm curved towards the west-southwest. Tropical cyclone is defined as a non-frontal, synoptic-scale cyclone developing over tropical and sub-tropical waters at any level and having a definitely organized circulation. Tsiouris , Pezoulas VC, Zervakis M, Konitsiotis S, Koutsouris DD, Fotiadis DI. [12][230][231][232] A state of calamity was declared for Surigao del Norte,[233][234] prompting an intense relief effort amid an ongoing cholera epidemic and unrelated flooding. damage. 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 October3. Prediction of a typhoon track using a generative adversarial network and satellite images.

[93][94] Rough surf from Helen reached the Tokyo area, drowning 13people. As the eye of the typhoon approaches, the weather will worsen continuously, with winds increasing to its strongest coming generally from the north. [citation needed]. Accurate classification or prediction for typhoon intensity is crucial to disaster warning and mitigation management. SSBN Typhoon or Akula (Shark) class submarine is a Soviet/Russian nuclear ballistic missile submarine. Weather Bureau called LouiseMarge one of the most destructive storms ever documented in the central Philippines. . Can. Tropical cyclones with maximum sustained surface . [253] A freighter was driven ashore by the typhoon at Jose Panganiban. [87] The typhoon passed within 160km (100mi) of Iwo Jima around noon that day. [124] Over 4,000people were rendered homeless. [34][12]:74 The storm weakened over mainland China and dissipated on May30. Kathy's winds razed 44houses and damaged 80houses, with another 5,500 flooded by swollen rivers. 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). [149][153][99] Over 10,000people 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. Fran began its development northwest of the Marshall Islands around October13. [206][205] Fran continued north before curving east after October20, eventually transitioning into an extratropical system by October21 and dissipating on October23 over the open Pacific. This paper presents an algorithm based on YOLO V5 for tropical cyclone measurement. [218] Louise was unusually close to the equator for a storm of its intensity; persisting at a strength equivalent to a Category5 hurricane on the SaffirSimpson scale at 7.3N, closer to the equator than any other Northern Hemisphere tropical cyclone of such intensity. A sudden improvement of the weather with light winds will be experienced, which means the area is under the eye of the typhoon. May limang (5) classification ang mga bagyo sa Pilipinas, ang una at pinakamahinang bagyo ay TROPICAL DEPRESSION na may lakas ng hangin na umaabot hanggang 61kph malapit sa gitna, samantala ang TROPICAL STORM ay bagyong may hanging 62 kph hanggang 88 kph. [35][110] Another seven people were killed in Korea following rains associated with Ida. [12]:77 U.S. Marine Corps helicopters were deployed to evacuate those affected by the storm in Tam K, Vietnam. All damage figures will be in 1964USD. Clipboard, Search History, and several other advanced features are temporarily unavailable. Abstract A tropical cyclone, also known as a typhoon, is one of the most destructive weather phenomena. [134][12]:76[6]:155 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 August20. [12]:77 An eye emerged on Nimbus satellite imagery on September20,[174]:159 and on September21, Wilda reached its peak intensity over the Philippine Sea with one-minute maximum sustained winds of 280km/h (175mph) as estimated by the JTWC and a minimum central pressure of 895hPa (mbar; 26.43inHg). [65], After passing the Ryukyu Islands and entering the East China Sea, Betty continued to intensify further, with its sustained winds reaching 205km/h (125mph) on July5. Pamela moved towards the west-northwest and subsequently weakened; on August26, the system weakened to a tropical depression and dissipated after a center of circulation could not be identified by aircraft reconnaissance. . [197][6]:205 Aircraft reconnaissance first encountered the system on October6, finding a developing tropical storm 160km (100mi) southwest of Yap. [40] Viola generated a 0.94-meter-high (3.08ft) storm surge at Quarry Bay and grounded four ships, including three freighters at Hong Kong. The combined effects of Iris and Joan killed as many as 7,000people and led to the worst floods in six decades. The following day, the a pressure of 1000mbar (hPa) was recorded in the center of the storm; however, this reading was not taken at the storm's highest intensity. The CMA and HKO estimated a central pressure of 960hPa (mbar; 28.35inHg) during Ruby's landfall. Due to the rapid succession of tropical storms Iris and Joan, widespread flooding and catastrophic flooding was reported across central South Vietnam. The most important use of data classification is to understand the . [46][58] Manila was placed under a state of emergency following Winnie, with government agencies deploying medical and rescue teams to affected areas amid widespread power outages. Tent homes in Angaur and Peleliu were inundated by storm surge. Gusts may be much higher than the mean wind speed and can exceed 220 km/h. 10 from the Royal Observatory and forced the suspension of public transportation and incoming flights. The 1964 Pacific typhoon season was the most active tropical cyclone season recorded globally, with a total of 39 tropical storms forming. The following day, Anita made landfall near Da Nang, Vietnam, and later weakened over land; the storm dissipated on September28. Natural disasters and land grabs:The politics of their intersection in the Philippines following super typhoon Haiyan. [146] Widespreading flooding and damage occurred in Guangdong Province, leading to the deaths of over 700people; some 300people died when a school dormitory collapsed. The first three categories, namely TD, TS and STS, remain the same as before. -, Corcione V., Nunziata F., Migliaccio M. Megi typhoon monitoring by X-band synthetic aperture radar measurements. A new type of the ships have been developed, as a reac. [52] Catholic Relief Services aided in disaster relief with funding from USAID. [12]:77 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. At around 06:00UTC on October21, 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 65km/h (40mph). Tropical cyclones with an organized system of clouds and thunderstorms with a defined circulation, and maximum sustained winds of 38 mph (61 km/h) or less are called "tropical depressions". The Typhoon-class has 19 different compartments to house 160 sailors. [52][46][55] Several aircraft were damaged, including 15C-47 Skytrains at Nichols Field. The lowest classification used by the Typhoon Committee is a tropical depression, which has 10-minute sustained winds of less than 34 kn (17 m/s; 39 mph; 63 km/h). [85], Helen began within a region of sparse weather observations east of the Northern Mariana Islands on July27, starting with a northward track that curved towards the northwest. [223] The U.S. A tropical cyclone generates winds that surpass 119 km (74 miles) per hour by drawing energy from the sea surface and sustaining its strength . [133][23][6]:63 According to the JTWC, Lorna's winds topped out at low-end tropical storm speeds, 65km/h (40mph), for less than a day before it began to weaken. At the time, it was located southeast of Wake Island. This initial disturbance traveled west-northwest, passing near Ulithi and Yap. With a displacement of 48,000 tons while submerged, the Typhoon is a true behemoth in scale. [12]:77 The JTWC assessed the system to have reached tropical storm status on October2. [256][257][258], 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 season. [84], Tropical Storm Grace was the first of ten tropical cyclones in the 1964typhoon season discovered by meteorological satellites. [198][12]:77 The storm then quickly weakened inland, transitioning into an extratropical cyclone on October15 and curving northeast back into the Pacific before it was last noted off Japan on October19. Firstly, the GridSat data set and the satellite of China Meteorological Administration were used to analyze the tropical cyclone scale data, and the typhoon data set was established. [158][154] However, Sally's impacts on the Crown territory were less than initially feared;[159] much of Hong Kong's vulnerable agriculture was already badly damaged during Ruby's passage. Bookshelf But typhoon intensity-related feature extraction is a challenging task as it requires . 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.). Wilda brought 6-meter (20-foot) waves to southern Kyushu. 2016;75:10771081. [185][186] Gale-force winds from Wilda reached the Tokyo area, damaging roofs at the Tokyo Olympic Village and uprooting trees two weeks before the start of the 1964 Summer Olympics. [6]:47 Ten of these occurred in the South China Sea, compared to the annual average of 3.2 in the five years preceding 1964. [161] Local authorities reported the inundation of 9,152homes and the displacement of 36,665people;[162] total property damage amounted to $750,000. [13] No year prior to 1964 featured more than two typhoons affecting Hong Kong on record. The system moved west- northwest and was identified as Tropical Depression 27W on November 1, 1991. [34] This system initially moved towards the north before curving sharply east. Typhoon Haiyan (Yolanda)- 2013 ; Typhoon Yolanda is one of the strongest tropical cyclones that hit the Philippines on November 8, 2013. HHS Vulnerability Disclosure, Help doi: 10.1109/JOE.2017.2700558. [176] The typhoon caused 47fatalities and 530injuries in Japan. 1866, June 5-9 - severe typhoon in provinces of Cagayan, La Union, Ilocos, and Abra . [147], Sally's precursor arose from a tropical wave near the Marshall Islands on September2. [219][218][12]:78 Louise continued to intensify after passing the island, and attained its peak intensity on November18 with one-minute sustained winds of 305km/h (190mph) and a central air pressure of 915hPa (mbar; 27.09inHg). Typhoons are some of the most serious natural disasters, and the key to disaster prevention and mitigation is typhoon level classification. Typhoon classification is introduced to facilitate the public in recognizing more intense typhoons, prompting people to be extra vigilant with the approach of more intense tropical cyclones. [12] The effects of typhoons in 1964 led to a 3.1percent decrease in rice output from the Philippines. [169] At least three people went missing in Thailand following the flooding from Tilda. +61 (07) 3215 8888 | enquiries@vmlearning.com.au. That is, we could have a strong but not large typhoon, and also a large but not strong typhoon. In order to explore the impact of pandemics on people's lives, it is . The typhoon weakened further as it moved over Luzon. [6]:141 This system developed into a tropical storm the next day east of Iwo Jima based on ship observations. [68][12]:75 Storm warnings were issued in southeastern Luzon with Cora 100km (60mi) east of Samar, with forecasts projecting stormy conditions in the region and in other islands in the east-central Philippines. FOIA Fig. [6] Louise became a typhoon the next day and passed 22km (14mi) south of Angaur with one-minute sustained winds estimated at approximately 185km/h (100mph). [198][201] At Tate's Cairn, a maximum wind gust of 220km/h (137mph) was measured. [12][99] Newswires reported disparate death tolls, with the Associated Press reporting 14fatalities, the Philippine News Service reporting 23, and United Press International reporting 79. [248] Rough seas from Opal off Okinawa swept two people off a ship stranded on a reef during a rescue operation, leading to their deaths. Typhoons are the same weather phenomenon as hurricane s, and both . [61], On June26, a disturbance formed from an easterly tropical wave southeast of Guam and strengthened into a tropical depression later that day. LouiseMarge began as a cyclonic vortex associated with a tropical wave near Yap State on November12. The super typhoon category and Signal No. dollars.[204]. A Typhoon class submarine on the surface in 1985. Typhoons and hurricanes form in the exact same way, from warm tropical water. [6][12][148], Sally inflicted around $115,000 in damage in Guam, mostly to crops, after bringing gusts of 130km/h (80mph) to the island and unroofing homes and felling trees. Typhoon is classificated by size. "[67] The Royal Observatory Hong Kong analyzed a substantially lower pressure of 920hPa (mbar; 27.17inHg) at the time of Cora's peak strength. [22] Between August1019, a progression of cyclones in the upper troposphere triggered wind perturbations closer to the ocean surface, leading to the genesis of Tropical Storm June, Typhoon Kathy, Tropical Storm Lorna, and Tropical Storm Nancy. [112] At Quarry Bay, Ida produced a storm surge of 1.31m (4.3ft). Opal crossed northwestern Luzon and the Babuyan Islands on December16 and later became extratropical near Okinawa on December17; this phase of Opal's development dissipated the next day. Over 70,000homes were destroyed and nearly 45,000were inundated by the typhoon across the country,[177] leaving thousands of people homeless. The https:// ensures that you are connecting to the On September5, Ruby attained maximum one-minute sustained winds of 220km/h (140mph) as it made landfall near Hong Kong and Macau.
