Meteorological history
In mid-August, a tropical disturbance developed within the Intertropical Convergence Zone over the Philippine Sea.[1] By August 19, the Japan Meteorological Agency (JMA) began monitoring this system as a tropical depression.[2][nb 1]Additionally, the Joint Typhoon Warning Center (JTWC) classified the system as a tropical storm.[4][nb 2] Initially, a strong ridge over Southeast Asia caused the storm to track slowly west-northwestward; however, the ridge gradually weakened over the following days.[1] The cyclone gradually strengthened to typhoon status on August 21, by which time it had developed a 32 km (20 mi) wide eye. Upon becoming a typhoon, the JTWC named the system Iris. Later on August 21, Iris turned northwestward as the ridge weakened and brushed the northeastern tip of Luzon.[1][4] On August 22, Iris attained its peak intensity as a Category 2 equivalent typhoon on the Saffir–Simpson Hurricane Scale with winds of 165 km/h (105 mph).[4] Later that day, United States Air Force reconnaissance plane flew into the storm and recorded a barometric pressure of 966 mbar (hPa; 28.53 inHg), the lowest in relation to the storm. After passing roughly 75 km (45 mi) south of Taiwan, known as Formosa at the time, Iris started weakening. Late on August 22, Iris made landfall near Kao-Chi, China as a strong tropical storm. The storm then rapidly transitioned into an extratropical cycloneover China before dissipating late on August 23.[1]
Impact
On August 21, Typhoon Iris brushed the northern coast of Luzon; however, there were no known reports of casualties or damage on land. Offshore, large swells produced by the storm were blamed on at least two shipwrecks.[6] Following the incidents, the United States Seventh Fleet were sent to search for survivors.[7] Near Palawan Island, at least 100 people drowned after a ferry sank; only 11 passengers were rescued. Five more people went missing near Quezon Province after their motorboat capsized.[6] Heavy rains from the typhoon spread across Taiwan on August 22, triggering significant flash flooding. Along the Haifenglun River, a railroad bridge was washed away.[8] Across the Pescadore Islands, approximately 1,000 people were left homeless.[9] Across Fujian Province, torrential rains from the typhoon led to catastrophic flooding that killed at least 720 people, injured 618 and left 996 others missing;[6][10] however, according to the National Oceanic and Atmospheric Administration, the death toll may be as high as 2,334.[11]
