Typhoon Cecil (1982)

Typhoon Cecil, known in the Philippines as Typhoon Loleng, was a mid-season tropical cyclone that affected Japan and South Korea during August 1982. An area of disturbed weather formed to the north of Truk on July 31 and tracked westward over the next several days. Following an increase in shower activity and a decrease in wind shear, a tropical depression developed on August 4. Two days later, the depression strengthened into a tropical storm. After turning northwestward and then northward, Cecil intensified into a typhoon on August 7, and then began to deepen at a rapid clip. On August 8, Cecil attained its maximum intensity as it brushed Taiwan. There, 19 people were killed, including 4 in Wugu District, where 2,800 families sought shelter. After pulling away from Taiwan, Typhoon Cecil moved northwestward, and then on August 10, turned to the north-northeast. Colder air, cooler waters, and higher shear contributed to a weakening trend, and Cecil was downgraded to a tropical storm on August 11. Although Cecil passed east of Japan, it came close enough to the country to drop heavy rains. Nation-wide, three people were killed and two were injured. A total of 2,100 households lost power in Hinokage. On August 14, Cecil turned east and struck South Korea as a minimal tropical storm before dissipating over the Sea of Japan. Throughout South Korea, 35 people were killed, 28 went missing, and 28 others sustained injuries. Almost 1,300 houses were flooded, which resulted in 6,200 people becoming homeless. Damage was estimated at US$30 million.

Meteorological history

The tropical disturbance that would later become Typhoon Cecil was first distinguishable as a low-level circulation about north of Truk on July 31. Over the next four days, the disturbance tracked westward and remained embedded in the monsoon trough, maintaining a closed surface circulation and an area of enhanced convective activity on satellite imagery. Initially, a Tropical Cyclone Formation Alert (TCFA) was not issued because strong easterly wind shear was expected to inhibit development. On August 4, following an increase in convective activity, a decrease in wind shear, and ship reports in the area measuring central pressures of , the Joint Typhoon Warning Center (JTWC) issued a TCFA. Meanwhile, the Japan Meteorological Agency (JMA) upgraded the system into a tropical depression. The JTWC upgraded the system into a tropical depression at 06:00 UTC on August 5 after a Hurricane Hunter aircraft mission observed sustained winds of .

The depression continued to track westward under the influence of easterly steering currents along the southern periphery of a subtropical ridge. On August 6, both the JTWC and the JMA classified the depression as Tropical Storm Cecil. Cecil briefly turned southward, slowed down, and then curved northwestward. At 00:00  UTC on August 7, the JTWC upgraded Cecil into a typhoon, with the JMA following suit several hours later. Over the ensuing 24 hours, Cecil entered a period of rapid deepening, and by 00:00 UTC on August 8, the JTWC had raised the intensity to . Midday on August 8, the JMA reported that Cecil attained its peak intensity of and a minimum barometric pressure of . The JTWC estimated that Cecil attained a peak intensity of at 18:00 UTC while located east of Taiwan.

As Cecil approached Taiwan from the southeast, it turned sharply northward until reaching the 25th parallel north when Cecil once again assumed a more northwestward track. On August 10, Cecil turned toward the north-northeast and the combined effects of colder ocean temperatures, vertical wind shear, and colder air aloft began to take their toll. On August 11, the JTWC downgraded Cecil to a tropical storm as it tracked northward under the influence of a subtropical ridge. That same day, the JMA briefly downgraded Cecil to a severe tropical storm, although data from the agency suggested that Cecil reached a secondary peak intensity of that evening. At 00:00 UTC on August 12, the JMA downgraded Cecil back to a severe tropical storm for the final time. The next day, Cecil was downgraded to a tropical storm by the JMA. By August 14, Cecil had passed to the east of Japan was beyond the northward influence of the subtropical ridge and began to track eastward, striking South Korea as a minimal tropical storm. Cecil's circulation was unable to reorganize after crossing the Korean peninsula and dissipated in the Sea of Japan on August 15, with the JMA ceasing to track the system at 06:00 UTC.

Impact

Although Cecil never approached closer than to Taiwan, the outer rainbands of the typhoon lashed Taiwan with heavy rains, where fell in the capital of Taipei during a 32-hour time span. A landslide killed 18 people in the Wugu District, where 4 people were rendered missing and 2,800 families were stranded. Flash flooding claimed one life and resulted in four others missing in Taoyuan. Overall, 19 people perished in the country. After passing Taiwan, rough seas caused by the storm near the Ryukyu Islands left the ''World Cosmos'' and ''Marvie'' ships in distress. The storm dropped heavy rainfall across much of Japan. A peak rainfall total of occurred at Nakagoya Station, including a record in 24 hours. Within an hour, fell in Nishimera. Moreover, a wind gust of was recorded in Tshigaki. Nation-wide, three people were killed and two others were wounded in Miyazaki Prefecture and Oita Prefecture. In Hinokage, 2,100 homes lost electricity and 500 residents were evacuated from their homes.

Because Cecil, at the time of landfall, was only a minimal tropical storm, the primary threat associated with the storm across South Korea was heavy rainfall. The storm dumped of rain in some places, including in Sancheong County. These rains resulted in landslides in 10 provinces. Nationwide, 35 people were killed, 28 were missing, and 28 were hurt. Nearly 1,300 houses were flooded, leaving 6,200 people homeless. Sancheong County along with the city of Changwon were the hardest hit by the storm, where three mudslides killed nine people and left six missing. In all, damage in the country amounted to US$30 million.
