Typhoon Judy of July 1989 was a strong tropical cyclone that caused extensive damage and loss of life in Japan, South Korea and the eastern Soviet Union.

Originating from a monsoon trough on July 21, Judy began as a tropical depression west of the Northern Mariana Islands.

Striking Kyushu on July 27, interaction with the island's mountainous terrain caused Judy to quickly weaken as it neared South Korea.

The weakened storm struck the country west of Pusan the following day before losing its identity near the border with North Korea.

Flooding from the remnants of Judy affected the Soviet Far East, temporarily severing the Trans-Siberian Railway and killing 15 people.

Within hours of reaching this strength, the a weather buoy near the storm recorded a barometric pressure of 974 mb (hPa; 28.76 inHg) and winds of 105 km/h (65 mph).

Strengthening continued throughout the day and Judy soon attained its peak intensity as a Category 2 equivalent typhoon on the Saffir–Simpson hurricane scale, with maximum sustained winds estimated at 175 km/h (110 mph).

[2] Around this time, the Japan Meteorological Agency assessed the typhoon to have attained ten-minute sustained winds of 155 km/h (95 mph) and a pressure of 940 mbar (hPa; 27.76 inHg).

Less than a day after moving over Kyushu, the system weakened to a tropical storm and soon made landfall in South Korea, roughly 205 km (127 mi) west of Pusan.

[2] On July 26, the Japan Meteorological Agency began warning residents of the typhoon's imminent arrival, stating that Judy would approach western parts of the country in two days.

[10] Winds up to 125 km/h (80 mph) battered coastal areas of South Korea, uprooting many trees and leaving thousands without power.

[18] The remnants of Judy produced heavy rains in the Soviet Far East in early August, resulting in significant flooding.
