Typhoon Sepat, known in the Philippines as Super Typhoon Egay, was the eighth named tropical storm and the strongest tropical cyclone of the 2007 Pacific typhoon season, that affected the Philippines and made landfall in Taiwan and Fujian. Sepat originated on August 11 via a low-circulation center SE of Naha, Okinawa, and was named by the Japan Meteorological Agency as Sepat on August 12 and Egay in the Philippines by PAGASA as it entered the PAR. Sepat underwent an explosive intensification on the night of August 13, reaching peak intensity at Category 5-equivalent super typhoon intensity the following morning. The storm maintained its strength for 2 days, until it underwent an eyewall replacement cycle, just before he storm makes landfall in Taiwan on August 17 (+21:00 UTC) as a Category 3-equivalent typhoon. After crossing the Taiwanese strait, Sepat; already weakening into Category 1 status due to unfavorable conditions, made a second landfall in China on August 18, 2007. The storm persisted across Mainland China, as it transitioned into an extratropical cyclone on August 20, and Sepat, now an extratropical low continued through the Chinese mainland until it finally dissipated near Yunnan Province on August 24.
More than 43 deaths were directly blamed on Sepat; 3 out of the 43 were from the Philippines due to drowning brought on by heavy rains from the southwest monsoon enhanced by Sepat, with total insured losses estimated at $692 million (2007 USD), or $869.66 million (2020 USD; adjusted for inflation).
