[73][6]:50 Rainy squalls associated with Elsie caused extensive flooding in Manila and the northern Philippines, inundating buildings and streets. 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. [115][22] Later that day, June attained a tropical storm and reached its peak intensity with winds of 75km/h (45mph). [197][6]:205 Aircraft reconnaissance first encountered the system on October6, finding a developing tropical storm 160km (100mi) southwest of Yap. Track of Tropical Storm Uring (Thelma) in November 1991, the deadliest tropical storm in Philippine history. [208][12]:77 Hope continued to track west before curving north on October25 towards an eventually northeastward track. [72][12]:75 The next day, Doris attained one-minute sustained winds of 150km/h (90mph). [12]:75 Betty's winds subsequently began to diminish precipitously while the storm curved towards the north and then north-northeast, briefly paralleling the coast of Zhejiang before entering the Yellow Sea. [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 terms "hurricane" and "typhoon" are regionally specific names for a strong "tropical cyclone".A tropical cyclone is the generic term for a non-frontal synoptic scale low-pressure system over tropical or sub-tropical waters with organized convection (i.e. Classification. 1639, June 27 - destructive typhoon over Manila Bay; great . Weather Bureau called LouiseMarge one of the most destructive storms ever documented in the central Philippines. [34][12]:74 The storm weakened over mainland China and dissipated on May30. Sensors (Basel). [173] The JTWC recognized the storm as a tropical cyclone on September19 when it was located roughly 370km (230mi) northwest of Saipan, and assessed Wilda to have strengthened into a typhoon later that day. Ferry services were suspended in the territory. Olga weakened to a tropical depression on August25 and degenerated into a non-circulating cluster of thunderstorms later that day. Classification and intensity values will be based on estimations conducted by the JMA. [124] Kathy's effects flooded almost 1,700homes and destroyed 8others in Amami shima; winds there reached 138km/h (86mph). [7], A recommendation was made at the 20th session of the United Nations Economic Commission for Asia and the Far East (now known as the UN Economic and Social Commission for Asia and the Pacific [ESCAP]) in March1964 for the United Nations Secretariat and World Meteorological Organization to investigate the feasibility of a multinational program for monitoring typhoons. [12]:77, Tropical Storm Anita formed just west of Luzon on September23. [142] The strong winds and heavy rain caused widespread damage in Hong Kong, destroying thousands of homes and damaging thousands of others. Schematic diagram of Graph Convolutional Network (GCN) structure. 5 were introduced back in 2015, taking into account the death and destruction caused by Super Typhoon Yolanda (Haiyan) in 2013. 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. [62] According to the agency, Alice was the smallest typhoon of 1964, with a radius of 320km (200mi). The Philippines is prone to tropical cyclones due to its geographical location which generally produce heavy rains and flooding of large areas and also strong winds which result in . Wilda made a final landfall on the western coast of northern Honshu on September25 as a tropical storm, thereafter departing Japan and quickly moving towards the central Aleutian Islands as a powerful extratropical cyclone. That is, we could have a strong but not large typhoon, and also a large but not strong typhoon. How does the new classification affect the Tropical Cyclone Warning System in Hong Kong? [9] Prior to the inception of the Typhoon Committee, the United States Indo-Pacific Command had designated the U.S. Fleet Weather Central in Guam as the JTWC in May1959. [30]:46 The JTWC assessed Alice to have briefly attained typhoon status on June27 with sustained winds of 120km/h (75mph). 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". [72][6][12]:75 Doris became a tropical storm by 12:00UTC that day as it began to track northwest across the Philippine Sea. The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. [164] On September16, the center of Tilda passed 95km/h (60mi) south of Hong Kong. Its center passed between Alamagan and Guguan on May20 while maximum sustained winds in the typhoon were 140km/h (85mph). [6] Tracking towards the west-northwest, it passed near Chuuk and became a tropical depression on July11 while 480km (300mi) south of Guam. [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. GCLSTM model; deep learning; prediction system; satellite image; typhoon. [29], Tess tracked towards the northeast after reaching typhoon intensity. [127] As Kathy moved across southern and central Kyushu, damage was reported in Kagoshima, Kumamoto, Miyazaki, and Oita prefectures. 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. Flooding broke through river embankments in 37locations and washed away 18bridges. [211] On November4, Iris intensified into a minimal typhoon, attaining winds of 120km/h (75mph)[212] and featured a circular 18mi (29km) wide eye. Tropical depressions in this basin have the "W" suffix added to their number. This can often result in the same storm having two names. Tropical cyclones are classified in accordance with the World Meteorological Organization's recommendation by their maximum sustained wind speeds near the centre. In Hong Kong, the classification is defined in terms of wind speeds averaged over 10 minutes. With effect from 2009, a new classification is used and consists of 6 categories as follows:, The former classification consists of only 4 categories. Typhoon timeline of 1964. [6]:104 Intensification was rapid upon developing, with Cora becoming a typhoon by the end of July6. First, we used the locally constrained fuzzy c-means (FCM) clustering method to identify typhoon-dominant cloud systems. [80][12]:75 The USS Tawasa was dispatched to tow the stricken Weiss out to sea, but was itself grounded on an unforeseen pinnacle upon dislodging the Weiss. Ocean. [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. Tracking towards the west-northwest, Ida reached typhoon intensity on August4. [73] At 04:00UTC the next day, an aerial reconnaissance mission into Elsie estimated that the storm's winds reached 185km/h (115mph). The JTWC was tasked with warning U.S. government agencies on tropical cyclones in the northwestern Pacific, in addition to researching and orchestrating aircraft reconnaissance into such storms. On August4, the storm weakened and dissipated west of Kyushu. Sci. [26] In September, tropical cyclone activity was high across the Northern Hemisphere in both the Atlantic and Pacific. It then crossed into the South China Sea where intensification continued as the Georgia's one-minute sustained winds reached 85km/h (50mph). For mor. Two days later, Cora attained sustained winds of 260km/h (160mph) as it approached the central Philippines on a westward heading, according to the JTWC;[12]:75 this classified Cora as a super typhoon. [88] On August3, Helen weakened to a tropical storm and made landfall near Dalian in Liaoning. [166], On September19, the JTWC determined that Tilda reintensified into a typhoon after the storm began to move west. On August23, Kathy made landfall on Kagoshima Prefecture with winds of 130km/h (80mph) and weakened to a tropical storm as it crossed the Seto Inland Sea and southern Honshu. [211], Tropical Storm Iris brought significant rainfall to parts of Vietnam, resulting in significant flooding. [98][12], Eleven deaths in Luzon were attributed to Ida according to data from the Office of Foreign Disaster Assistance, in addition to flooding and crop damage throughout the island. Super Typhoon Haiyan, also known as Super Typhoon Yolanda, made landfall in the Philippines on Nov. 8, 2013, as a Category 5 storm. As the eye of the typhoon approaches, the weather will worsen continuously, with winds increasing to its strongest coming generally from the north. [6]:81 Viola reached tropical storm strength on May25 and then curved northwest, strengthening further into a typhoon on May27 and peaking in strength with winds of 130km/h (80mph). Thirteen fishermen were overcome by the 7.6-9.1 m (25-30 ft) swells off the coast of Weizhou Island. 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. 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 pictures of the Himawari-8 satellite in 2010-2019. Its intense cyclonic eddy circulations often cause serious damage to coastal areas. Set the target area : South North West East. [172][12]:77, The storm generated rainfall totals in excess of 190mm (7.5in) between September1417,[167]:76 punctuated by a maximum measured value of 245mm (9.6in). [209][6]:2125 Though winds as high as 240km/h (150mph) were estimated by aircraft reconnaissance investigating the typhoon during this period,[12]:78[6]:214 Hope's one-minute sustained winds in the JTWC's tracking data peaked at 140km/h (85mph). [6]:14 The initial vortex that became Tilda formed by September12 and organized into a tropical depression by September13. [144]:1 Numerous ships sank or ran aground at the Hong Kong Harbor. How often will Hong Kong have a direct hit of a super typhoon or severe typhoon? 2020 Dec;50(12):4946-4957. doi: 10.1109/TCYB.2019.2920268. 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. The depression quickly strengthened into Tropical Storm Kate the same day. 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. 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. [46] Approximately 500,000people were rendered homeless in the Manila area and in the central provinces of Luzon following the razing of thousands of homes;[54][12]:74 most of these homes were nipa huts and "makeshift dwellings". [173] The storm passed over Shikoku and southern Honshu before emerging into the Sea of Japan and curving northeast. [10] Ten of the year's tropical cyclonesGrace, Helen, Nancy, Pamela, Ruby, Fran, Georgia, Iris, Kate, Louise, and Opalwere first detected using meteorological satellites. Super typhoons are the equivalent of a at least a high-end Category 4 hurricane on the . [118][119] The typhoon's winds peaked at 165km/h (105mph) on August14 before tapering as the storm curved towards the west-southwest. Definition. Fig. [117][12]:76 On August25, Kathy transitioned into an extratropical cyclone and continued northeast towards the Aleutian Islands before it was last in the Bering Strait on September1. In summary, the results can provide a theoretical basis for the related research of typhoon level classification. 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. [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. It then recurved creating a loop and finally exited to South China Sea. Tropical Cyclone Formation and Activity Calendar of 1964. [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. Try Speed Dating! Gusts may be much higher than the mean wind speed and can exceed 220 km/h. [227] Widespread destruction occurred in Surigao City, where the storm killed 312people and caused US$12.5million in damage. The following day, the system quickly organized as it moved in a general eastward direction. Accessibility duration, name, areas affected, deaths, missing persons (in parentheses), and damage totals. +61 (07) 3215 8888 | enquiries@vmlearning.com.au. [180] Damage was widespread in the northern Ryukyu Islands. [34] This system initially moved towards the north before curving sharply east. The Session will also cover the new Strategic Plan 2022-2026 and development issues. It's a simple strategy to use, and I'll walk you through it here in about one minute. [192][191]:53, Sixteen people were killed by floods triggered by Billie's rains in Camarines Sur. [29] A seabee stationed on the island was presumed to have drowned after being swept away by the rough seas generated by the storm; two landing crafts were also destroyed by the rough seas. 2017;43:184194. [135][22], Olga remained within the Gulf of Tonkin for the entirety of its existence, taking a southward trajectory. Tropical Cyclone Classification. official website and that any information you provide is encrypted However, a few days after Iris moved through the country, Tropical Storm Joan worsened the situation significantly. [98] Between August67, Ida moved across northern Luzon with these winds. [91] One death and 16injuries were reported in the two prefectures. [6] It became a tropical storm over the central Philippine Sea on September1 and took a slightly south of west heading, strengthening into a typhoon on September2 and passing over the Babuyan Islands of the Philippines the following day; one-minute sustained winds at the time were estimated to be 140km/h (85mph). [6]:141 This system developed into a tropical storm the next day east of Iwo Jima based on ship observations. In Hong Kong, such sustained wind speeds are rare over land and are usually experienced during the close passage of a mature typhoon. [6]:i Boeing B-47 Stratojets were deployed from the 54th Weather Reconnaissance Squadron to carry out airborne reconnaissance. doi: 10.7717/peerj-cs.953. [168] Tilda continued inland and weakened before dissipating by September25. [6]:115 Storm warnings were posted for Luzon on July17 ahead of the storm's approach. What is a category 5 super typhoon? [12] More storms passed near Hong Kong in 1964 than in any prior year. At the time, it was located southeast of Wake Island. [158] The remnants of Sally led to the heaviest rainfall in the Seoul area in 22years, producing 125200mm (58in) of rain in the area on the morning of September13. [70][71] By July10, Cora had weakened to a tropical depression. Dot then curved towards the west and made landfall on northern Luzon the following day with one-minute sustained winds of 130km/h (80mph). [213], Similar to the formation of Tropical Storm Iris, Tropical Storm Joan originated from a tropical disturbance over the western South China Sea on November5. doi: 10.1038/s41598-019-42339-y. doi: 10.2112/SI75-216.1. 1866, June 5-9 - severe typhoon in provinces of Cagayan, La Union, Ilocos, and Abra . [213], The deadliest storm of the 1964 season, Tropical Storm Joan brought heavy flooding that killed 7,000 people in Vietnam. i) Tropical Depression: Maximum wind speed at the center reaches 34 to 48 knots (17 m/s ~ 25m/s) . [12] At least 576people were killed, though the Philippine Red Cross recorded 631fatalities, along with 157missing people and 376,235people displaced by the typhoon. 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). [6]:98 The storm's winds continued to increase, and on July3 its winds reached 185km/h (115mph) before the rate of intensification stalled. The Royal Observatory Hong Kong issued tropical cyclone warning signals 42times for ten different storms; these warnings were in effect for 570hours. Thereafter, the storm began to take on extratropical characteristics, with its center of circulation enlarging and becoming irregular. Use tab to navigate through the menu items. Thelma began as a tropical disturbance over the Eastern Caroline Islands (Western Pacific region). [128][130] One landslide in Kagoshima killed 11people. [12]:75 An aircraft reconnaissance mission observed two concentric eyewalls spanning 11km (7mi) and 80km (50mi) across. Feature extraction result of some convolution kernels. [20] A strong high pressure area south of Japan caused most storms during July to take slow and westward paths. Proudly created with Wix.com. [193] Flooding swept away a bridge along a railroad of the Philippine National Railways, causing a passenger car to derail; one person was injured. Over 70,000homes were destroyed and nearly 45,000were inundated by the typhoon across the country,[177] leaving thousands of people homeless. The Graph Convolutional Network (GCN) is used to process the irregular spatial structure of satellite cloud pictures effectively, and the Long Short-Term Memory (LSTM) network is utilized to learn the characteristics of satellite cloud pictures over time. [4][5][6]:47 There were more named storms in the northwestern Pacific in 1964 than in any other year or in any other basin. [121][12]:76 United Press International reported as many as 24fatalities and 8missing persons associated with the typhoon,[122][123] with the Associated Press documenting 28injuries. On September5, Ruby attained maximum one-minute sustained winds of 220km/h (140mph) as it made landfall near Hong Kong and Macau. [237], Nora began within the Sulu Sea near the Cagayan Islands sometime around November2627, and became a tropical storm shortly after it was first detected. [101] Most communications were disrupted across northern Luzon. Violet's one-minute sustained winds topped out at 140km/h (85mph) just prior to moving ashore Vietnam. On Peleliu, 97percent of structures were destroyed, while 90percent of homes on Anguar were destroyed. Tracking eastward, the system quickly organized and was immediately declared a tropical storm on November6. Ellen dissipated on October 10 near Ponape. Early on July13, Doris strengthened into a typhoon while approximately 800km (500mi) east of Luzon. 1700 - 1800. The Session is being convened by the Typhoon Committee, under the auspices of the Economic and Social Commission for Asia and the Pacific (ESCAP) and the World Meteorological Organization (WMO), and hosted online by Macao Meteorological and Geophysical Bureau (SMG) of Macao, China. The typhoon still dumped more rains and threw its tempest by early morning of December 11 at Northern Palawan. (Dading) June 24 - July 4: Typhoon: 185 km/h (115 mph) 968 hPa (28.58 inHg . [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. [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. With the new typhoon classification, what will be the frequency of occurrence of different categories of typhoons? Keywords: So, The intensity and size represents different aspect of a typhoon. "[67] The Royal Observatory Hong Kong analyzed a substantially lower pressure of 920hPa (mbar; 27.17inHg) at the time of Cora's peak strength. The model can accurately identify the levels of different typhoons according to the satellite cloud pictures. "[17] Gradual weakening followed,[12]:74 with winds diminishing below typhoon intensity on May22. The rainfall brought an end to an over two-year-long drought that had prompted a year-long water rationing in the territory. [12]:78[251] Rice crops were damaged by heavy rainfall, and together with coconut crops, sustained losses estimated in the millions of U.S. [97], The origins of Typhoon Ida were associated with the interaction between a polar trough and a tropical wave, which resulted in the development of a tropical disturbance south of Chuuk State on August1. The system then began to curve east as it transitioned into an extratropical cyclone by May24, and was last noted three days later. The Typhoon-class has 19 different compartments to house 160 sailors. [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. Typhoon Haiyan (Yolanda)- 2013 ; Typhoon Yolanda is one of the strongest tropical cyclones that hit the Philippines on November 8, 2013. Schematic diagram of the Long Short-Term Memory (LSTM) model structure. [208] On October24, when it was west of Guam, the JTWC upgraded the system to tropical storm status based on aerial observations of the system. [6][17] Shower activity in the tropics west of Hawaii was above average between May1020. [29], According to data from the Japan Meteorological Agency (JMA), the progenitor to Typhoon Viola emerged in the South China Sea just east of Vietnam on May21. The authors declare no conflict of interest. The storm weakened over land, passing over southeastern Manchuria and Siberia, and was last monitored over Sakhalin. [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. Model accuracy under different convolution, Model accuracy under different convolution kernels. With the introduction of Starfleet's command battlecruiser via the games official Delta Rising expansion . Typhoon is classificated by size. [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). [139][140] After reaching the South China Sea, Ruby turned towards the northwest and intensified further. TYPHOON naman ang tawag sa bagyo na umaabot ang dalang hangin sa pagitan ng 118 kph . The new public storm warning signal system, signed last May 18, is as follows: PSWS No. [citation needed]. Tsiouris , Pezoulas VC, Zervakis M, Konitsiotis S, Koutsouris DD, Fotiadis DI. [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). During the afternoon, the JTWC issued their first advisory on the system, immediately declaring it Tropical Storm Iris. The names were drawn sequentially from a set of four alphabetical naming lists and were all feminine. So, The intensity and size represents different aspect of a typhoon. Eng. With a displacement of 48,000 tons while submerged, the Typhoon is a true behemoth in scale. [63] Betty took a northwestward trajectory towards the southern Ryukyu Islands,[12]:75 bringing its eye across southern portions of Miyakojima on July4. [12][111] The Royal Observatory documented rainfall rates as high as 230mm (9in) per hour from Ida. It then transitioned into an extratropical cyclone on July7 and dissipated over open waters just off the coast of northwestern South Korea. Typhoon is classificated by intensity. Why is typhoon classification introduced? [12]:76 Tilda's close pass of Hong Kong prompted the hoisting of storm signals to warn ships and small craft,[165] with the Royal Observatory escalating its warnings to typhoon signal no. Bookshelf [220] On November19, Louise made landfall on Lanzua Bay in Surigao del Sur, Philippines, with winds of approximately 260km/h (160mph). [152] Sally produced strong winds and heavy rains to the Philippines north of Manila, causing considerable damage. [12]:76 The typhoon's one-minue sustained winds were estimated by the agency at 205km/h (120mph) on September20 before weakening ensued. [22][138], The tropical disturbance that organized into Ruby arose from a tropical wave west of Saipan on August29. What is a typhoon: Everything you need to know. [6] The anomalous strength of tropical waves observed during the latter-half of the year may have contributed to season's high activity. [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. [12]:78[219] On December12, Opal reached its peak intensity with one-minute sustained winds of 315km/h (195mph) and a central pressure of 895hPa (26.43inHg). [53] At least 10people were killed by flooding rivers near Manila and in Manila Bay. Two of these storms, Ruby and Dot, prompted the highest warning signal, signal no. [195][12]:77 Warnings were raised for Clara across parts of eight Filipino provinces ahead of the storm's approach. Can. When underwater, the Typhoon-class displaces 48,000 tons. The storm weakened within the Gulf of Tonkin and struck Vietnam north of ng Hi on October8 with one-minute sustained winds estimated at 85km/h (45mph) by the JTWC. Clipboard, Search History, and several other advanced features are temporarily unavailable. [115], According to the JTWC, Kathy was both the largest and longest-lived typhoon in 1964, with the agency issuing warnings for 13.5days and the storm's circulation reaching a diameter of 1575km (850mi). Naze lost power during the storm. [150][30] The damage remained limited to the southern half of Guam where the storm struck;[151] there were no casualties. 3. These dates conventionally delimit the period of each year when most tropical cyclones form in the . [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). [12]:76, Lorna began west of the Mariana Islands on August10 and took a northeastward path throughout its duration. Bethesda, MD 20894, Web Policies As it tracked farther inland, Ida weakened and later dissipated on August12. PeerJ Comput Sci. In 2005 the Dmitry Donskoi, the only remaining example of the class still in active service, successfully tested Russia's relatively new RSM-56 . Further weakening ensued as the system tracked across northern Vietnam and southwest China before dissipating on July4. Nearly a million people were affected by the storm; according to the U.S. Agency for International Development (USAID), there were 56fatalities and 163injuries as a result of Winnie in the Philippines, with a damage toll of US$8million. The size of a typhoon is classified by the radius of the area in which the wind speed exceeds 15 m/s. The wave became Tropical Depression 45W on the 13th. Please add explanation of subfigures in caption. [29] Farther southeast, in Guam, the passing storm produced 52mm (2.03in) of rain. IEEE J. [183] At Uwajima, Ehime, a peak wind gust of 259km/h (161mph) was observed;[179] this was the strongest wind recorded in connection with the Wilda in Japan. [166][202][200] The official death toll from the storm in Hong Kong enumerated 26fatalities and 85injuries with 10unaccounted for,[13]:74 though press reports at the time indicated a higher death toll. Fig. [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. [39] Vegetable crops were badly damaged. [52][46][55] Several aircraft were damaged, including 15C-47 Skytrains at Nichols Field. [13] A record gust of 211km/h (131mph) was measured in Taipa, Macau. [63][6]:96, Typhoon Cora developed from the interaction of a polar trough with an easterly tropical wave. 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. [93][94] Rough surf from Helen reached the Tokyo area, drowning 13people. [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). [62] On June27, Alice made its closest approach to Guam, passing 95km (60mi) southwest of the island. USS Takelma (ATF-113) is an Abnaki . [63] At the time, the typhoon was located approximately 320km (200mi) south of Shanghai. Tropical cyclone classification varies between Typhoon Committee Members. 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.
