from the northwest Pacific monsoon trough. In addition, the typhoon developed an eye early on August 20, though in its initial stages the eye was irregular in shape. At 1200 UTC on August 21, the JTWC determined Bilis to have reached super typhoon intensity.. Six hours later, the JMA indicated that the typhoon had reached its peak intensity with maximum sustained winds of 205 km/h (125 mph) and a minimum barometric pressure of 920 mbar (hPa; 27.17 inHg). By this point Bilis' eye had become cloud-free and well defined. The typhoon maintained this intensity with little fluctuation for roughly the ensuing eighteen hours as it tracked northwest. Early on August 22, microwave imagery indicated concentric eyewalls, a sign of a possible eyewall replacement cycle. Still at peak intensity, Bilis made landfall on the coast of southern Taiwan at 1400 UTC on August 22. Concurrently, the storm's internal structure began to show signs of disruption, and its eye began to shrink. The typhoon accelerated over the island, and as such emerged into the Taiwan Strait no longer than five or six hours after landfall. Despite the short stint over land, Bilis had greatly weakened, and was only a minimal typhoon upon its reentry over water. However, there was a large discrepancy between JMA and JTWC intensity estimates, with the latter suggesting that Bilis had only weakened slightly. Nonetheless, the typhoon made its final landfall Jinjiang, Fujian at 0300 UTC on August 24. This greatly weakened Bilis, and three hours later the JMA downgraded it as a tropical storm. Shortly after landfall, the weakening tropical cyclone became quasi-stationary just inland of Mainland China. By this point convection was intermittent and short-lived, and at 1200 UTC the JMA classified the system as a tropical depression. Though the JTWC discontinued its monitoring activities, the depression began to assume a northerly course on August 24. At 1200 UTC the next day, the depression was determined to have diffused into a remnant low while still inland. Bilis' remnants continued to track northeast, across the Yellow Sea, and dissipated on August 27 shortly after entering the Korean Peninsula. Preparations and impact Taiwan In preparation for Bilis, offices were closed across the island. In addition to the closure of businesses, flights to and from the island were rescheduled, and a typhoon relief center was established. Due to the threat of landslides, a landslide warning was issued for Taiwan.
