Typhoon Cora (1966)

{{Storm path|Cora 1966 track.png}}

At 18:00 UTC on 28 August, a tropical depression formed just to the east of the Northern Mariana Islands. Although initially drifting southeast, the depression began curving to the southwest early the next day. During the late night of 29 August, it passed over the south tip of Guam and over the Cocos Lagoon.{{cite web|title=RSMC Best Track Data – 1960–1969|url=http://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/Besttracks/bst6069.txt|publisher=Japan Meteorological Organization|accessdate=9 August 2013|format=TXT|date=1 June 1989}} Early in the day on 30 August, the depression slowed its course and began a gentle turn to the west-northwest. By 00:00 UTC on 31 August, the depression attained tropical storm intensity and started moving northwest. Steadily strengthening as it did so, Tropical Storm Cora attained typhoon intensity by 00:00 UTC on 1 September. At that time, Typhoon Cora began a period of rapid deepening: its central pressure dropped {{convert|45|mb|inHg|lk=on}} in 24 hours, from {{convert|970|to|925|mb|inHg|sigfig=3|abbr=on}}. In the same period, between 00:00 UTC on 1–2 September, Typhoon Cora increased its maximum sustained wind speed from {{convert|85|to|145|mi/h|km/h|abbr=on}}.{{cite web|title=Best track – Western Pacific 07 Storm – 1966|url=http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1966/1966s-bwp/bwp171966.txt|archive-url=https://web.archive.org/web/20120916181743/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1966/1966s-bwp/bwp171966.txt|url-status=dead|archive-date=16 September 2012|publisher=Joint Typhoon Warning Center|accessdate=9 August 2013|format=TXT}} Having intensified significantly, Typhoon Cora progressively decreased its forward speed and bent back to the west-northwest over the next 36 hours. During this period, Typhoon Cora attained peak winds equal to those of a minimal Super Typhoon on the Joint Typhoon Warning Center's classification scale. At 12:00 UTC on 3 September, it turned to the west and maintained its wind speed of {{convert|150|mi/h|km/h|abbr=on}} for another 24 hours. On the night of 4 September, Typhoon Cora began yet another turn to the west-northwest and intensified into what is equivalent of a Category 5 super typhoon on the Saffir-Simpson Hurricane Scale; however, the classification did not exist until the scale was first devised in the 1970s and then used retroactively to rate past storms. Just before midnight UTC on 5 September, Typhoon Cora passed only {{convert|5|mi|km}} southwest of Miyako-jima Island, its northern eyewall impacting the island for several hours. During this pass, the central pressure in Typhoon Cora dropped to {{convert|918|mb|inHg|abbr=on}}, the lowest observed in its life span. However, Typhoon Cora did not reach its maximum wind speed of {{convert|175|mi/h|km/h|abbr=on}} for another 12 hours, until 12:00 UTC on 5 September.

After peaking at this intensity, Typhoon Cora continued moving west-northwest toward mainland China; around midnight UTC on 6 September, its eye passed {{convert|20|mi|km|abbr=on}} southwest of the Senkaku Islands. Between 12:00 UTC on 5 September and 00:00 UTC on 6 September, Typhoon Cora briefly fluctuated in intensity, its winds alternating between {{convert|160|–|175|mi/h|km/h|abbr=on}}; however, it generally maintained its intensity and remained at Category 5 intensity for one more day, until 00:00 UTC on 7 September, after a total of 42 hours spent at that level. Sometime before 00:00 UTC on 7 September, Typhoon Cora made landfall on Fujian, China, with estimated sustained winds of {{convert|160|mi/h|km/h|abbr=on}}, making it one of only two Category 5 typhoons to make landfall in the People's Republic of China.{{cite web|title=JTWC Western North Pacific Best Track Data|url=http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/wpindex.html|archive-url=https://web.archive.org/web/20100120054915/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/wpindex.html|url-status=dead|archive-date=20 January 2010|publisher=Joint Typhoon Warning Center|accessdate=9 August 2013|date=25 April 2013}} After making landfall, Typhoon Cora quickly lost typhoon intensity and curved to the northeast. It passed near Jinhua, Hangzhou, and Suzhou; by the time it was nearest Suzhou, it was already a remnant low. On 8 September, the remnant low turned to the northeast, over the East China Sea, and approached the Korean Peninsula. Shortly after 06:00 UTC on 9 September, it struck South Chungcheong Province in the Republic of Korea. Dissipation took place inland, six hours later.

As the typhoon approached Okinawa Island, flights to the island were cancelled for five days, stranding about 1,000 U.S. Marines in South Vietnam. The Marines were due to arrive on Okinawa, their staging area, but instead were sent to a camp in Da Nang, part of South Vietnamese territory in 1966.{{cite news|title=Storms Strand Marines Due to Leave Vietnam|newspaper=New York Times|date=5 September 1966|agency=The Associated Press}}

In the southern Ryukyu Islands, Typhoon Cora was considered the most destructive typhoon in at least 75 years. There, the powerful winds and waves of the storm destroyed 520 homes on the islands of Miyako-jima and Ishigaki. The worst damage occurred on Miyako-jima; the storm also damaged 1,400 homes, leaving 2,363 people homeless.{{cite news|title=Ryukyus Typhoon Leaves 2,363 Homeless on Island|newspaper=The New York Times|date=7 September 1966|agency=Special to the New York Times}} The majority of these were wooden structures whose structures were compromised once their roof was torn off. Steel structures also sustained considerable damage while reinforced concrete buildings fared the best. On the island, a Japanese weather observatory recorded sustained winds of {{convert|118|kn|mi/h|lk=on}} ({{convert|60.8|m/s|km/h|abbr=on}}), with a peak gust of {{convert|166|kn|mi/h|abbr=on}} ({{convert|85.3|m/s|km/h|abbr=on}}).{{cite web|title=第２宮古島台風 昭和41年（1966年） ９月４日～９月６日|url=http://www.data.jma.go.jp/obd/stats/data/bosai/report/1966/19660904/19660904.html|publisher=Japanese Meteorological Organization|accessdate=9 August 2013|language=Japanese}} The peak gust is still the official highest wind speed ever recorded in Japan. The lowest pressure on Miyako-jima island, {{convert|928.9|mb|inHg|abbr=on}}, was recorded at 10:01 a.m. local time on 5 September.{{cite web|title=月日時分|url=http://www.data.jma.go.jp/obd/stats/data/bosai/report/1966/19660904/19660904_b2.html|publisher=Japanese Meteorological Organization|accessdate=9 August 2013|language=Japanese}} In all, {{convert|296.1|mm|in}} of rain fell during Typhoon Cora.{{cite web|title=降水量表|url=http://www.data.jma.go.jp/obd/stats/data/bosai/report/1966/19660904/19660904_b1.html|publisher=Japanese Meteorological Organization|accessdate=9 August 2013|language=Japanese}} Additionally, up to five five-ton ships were destroyed and four others reported damaged. The powerful storm, while at peak intensity near Miyako-jima, also destroyed one of two radar bases there, and significant damage to crops was reported;{{cite news|title=Typhoon Knocks Out Radar Post|url=http://news.google.com/newspapers?id=Z51RAAAAIBAJ&sjid=dWwDAAAAIBAJ&dq=typhoon%20ryukyu&pg=2657%2C1254284|accessdate=5 August 2013|newspaper=Pittsburgh Post-Gazette|date=6 September 1966|agency=The Associated Press|location=Pittsburgh, Pennsylvania}} later estimates indicated 70% of the sugar cane on the island was destroyed. Total losses on Miyako-jima and Ishigaki reached $30 million (1966 USD).{{cite news|title=Typhoon Damage|url=http://news.google.com/newspapers?id=IsVOAAAAIBAJ&sjid=dAEEAAAAIBAJ&pg=1633,7071&dq=cora&hl=en|accessdate=5 August 2013|newspaper=Toledo Blade|date=8 September 1966|agency=The Associated Press|location=Toledo, Ohio}} Only five injuries were reported after Cora.

Slowly moving by the southern Ryukyu Islands, Cora battered the region for more than 30 hours. The resulting effects rendered 6,000 residents homeless. The scale of damage varied across the island with Ueno-mura suffering the most extensive losses. Of the community's 821 homes, 90.1 percent was severely damaged or destroyed. A United States Air Force radar station was destroyed on the island. On nearby Ishigaki Island, where wind gusts reached {{convert|162|km/h|mph|abbr=on}}, 71 homes were destroyed while a further 139 were severely damaged.

On nearby Taiwan (then called Formosa), Typhoon Cora produced strong winds along the north coast of the island. Peak winds in Taipei reached {{convert|70|mi/h|km/h|abbr=on}}.{{cite news|title=Typhoon's Winds Destroy Two Radar Stations|url=http://news.google.com/newspapers?id=FP0rAAAAIBAJ&sjid=B8gEAAAAIBAJ&dq=cora&pg=3372%2C737482|accessdate=5 August 2013|newspaper=Florence Times Daily|date=6 September 1966|agency=The Associated Press|location=Florence, Alabama}} Wind gusts up to {{convert|130|km/h|mph|abbr=on}} caused notable damage in Taiwan, with 17 homes destroyed and 42 more damaged. A smaller island closer to the storm reported a peak gust of {{convert|226|km/h|mph|abbr=on}}. Heavy rains were generally confined to northern areas of the island, peaking at {{convert|405|mm|in|abbr=on}}. Three people were killed during Cora's passage while seventeen others sustained injury. Additionally, 5,000 persons were evacuated. Damage amounted to NT$4.2 million. Striking Fujian Province, China, on the heels of Typhoon Alice, Cora exacerbated damage in the region. Property damage was extreme with more than 21,000 homes destroyed and nearly 63,000 more damage. An estimated 265,000 people were severely affected by the storm. A total of 269 people perished during the storm while a further 2,918 were injured; 52 people were also listed missing. Tremendous flooding occurred as a result of the rains from Alice and Cora, damaging {{convert|190000|ha|acre|abbr=off}} of crops which resulted in a loss of {{convert|195000|kg|lb|abbr=on}} in food production.

The JMA in Japan named the typhoon 2nd Miyako-jima Typhoon.

• Typhoon Sarah (1959) – the JMA named it Miyakojima Typhoon
• Typhoon Della (1968) – the JMA named it 3rd Miyakojima Typhoon
