Typhoon Abe, known as Typhoon Iliang in the Philippines, was the fourteenth named storm of 1990 Pacific typhoon season. Forming on August 23 from a tropical disturbance, the depression which would eventually develop into Typhoon Abe initially tracked in a steady west-northwestward direction. As a result of an intense monsoon surge, Abe's trajectory briefly changed to an eastward then northward path before returning to its original track. Abe only intensified by a small amount between 00:00 UTC August 24 and 06:00 UTC August 27 due to the disruptive effects of the surge, and on August 30, Abe peaked in intensity as a Category 2-equivalent typhoon on the Saffir–Simpson hurricane wind scale. After peaking in intensity, Abe crossed the Ryukyu Islands and the East China Sea, making landfall in China where it affected the provinces of Zhejiang and Jiangsu before entering the Yellow Sea, crossing South Korea, and finally transitioning into an extratropical cyclone. Typhoon Abe killed 108–195 people after it caused flooding and landslides in the Philippines and Taiwan, ravaged coastal areas of China, and brought high waves to Japan. Abe, which is responsible for killing 108 in China, affected half of Zhejiang's land area and a fourth of its population, leaving thousands homeless and causing ¥3.5 billion yuan (RMB, $741.5–743 million USD) to be lost in damages. Additional damage and one fatality occurred in Okinawa Prefecture in Japan, where at least ¥890 million yen (JPY, $6 million USD) in damage was caused. Meteorological history The tropical disturbance which would eventually intensify to become Typhoon Abe was first noted by the Joint Typhoon Warning Center (JTWC) in a Significant Tropical Weather Advisory as an area of persistent atmospheric convection on August 23 at 01:00 UTC. Located near the end of what the JTWC considered to be "an active monsoon trough", the initial minimum sea-level pressure was estimated to be approximately . Following this mention, the disturbance tracked in a mostly west-northwestward direction, traveling beneath a subtropical ridge, with a Tropical Cyclone Formation Alert being issued at 06:00 UTC based on the improving state of the low. Following an increase in the storm's central convection, the JTWC determined at 00:00 UTC August 24 that it had intensified into a tropical storm which it assigned the designation 15W, and the Japan Meteorological Agency (JMA) began to monitor the system six hours later. The JMA upgraded the system to a tropical storm on
