Truk. A second area of disturbed weather subsequently developed east of the Marshall Islands. The two areas consolidated into one on June 25, even though further development was initially slow to occur due to strong wind shear created by a tropical upper tropospheric trough near Wake Island. On June 25, the storm began to show signs of organization while tracking northwest; however, the JMA did not upgrade the system into a tropical depression until 00:00 UTC on June 26. On the next day, both the JTWC and JMA classified the system as Tropical Storm Sperry after the low-level center became better defined and the storm developed a central dense overcast – a large mass of deep convection. Later on June 28, Sperry was upgraded into a severe tropical storm by the JMA. On the next day, both agencies upgraded Sperry into a typhoon, the second of the season, based on reports from hurricane hunters. At noon on June 28, the JTWC and JMA reported that Sperry peaked in strength; the agencies estimated winds of respectively at this time. By June 29, Sperry began to approach a break in the ridge as well as a cold front, causing the storm to recurve to the northeast, becoming the first storm of the season to interact with mid-latitude westerlies. Thunderstorm activity quickly became displaced from the center due to increased wind shear, and the JMA downgraded Sperry into a severe tropical storm at 00:00 UTC on June 30. On the next day, both the JTWC and JMA declared Sperry an extratropical cyclone, although its remains later merged with a frontal zone. Typhoon Thelma (Katring) Thelma was first designated by the JMA as a tropical depression on July 7. After moving north, Thelma turned west, while remaining poorly organized. It finally attained typhoon status on July 9, soon after developing an eye, and began to intensify at a brisker clip, and on July 10, the JTWC upgraded Thelma into the first super typhoon of the season. During the evening of July 10, Thelma attained maximum intensity while well to the east of the Philippines. It also turned sharply northward in response to a trough while also slowly weakening. On July 15, Typhoon Thelma, now greatly reduced in intensity, struck the south coast of South Korea. The next day, Thelma rapidly dissipated, shortly after emerging into the Sea of Japan. 138 people were killed by
