Mirinae was first noted as a tropical depression during July 25, as it moved off the west coast of Luzon into the South China Sea, about 300 km (185 mi) to the east of the Paracel Islands.
The system's well defined low level circulation centre was located in a very favourable environment for further development, with low vertical windshear and very warm sea surface temperatures.
Later that day the JTWC initiated advisories on the system and classified it as Tropical Depression 05W, as it moved north-westwards along the periphery of a subtropical ridge of high pressure.
During the next day, as the system moved west-northwestwards, it continued to intensify was named Mirinae by the JMA after it had become a tropical storm.
Mirinae subsequently weakened slightly as it made landfall later that day, near Wanning and crossed Hainan Island, before it re-intensified as it had moved into the Gulf of Tonkin.
The system was classified as a severe tropical storm by the JMA during July 27, as it was estimated that Mirinae had peaked with sustained wind-speeds of 95 km/h (59 mph).
The system subsequently made landfall about 110 km (70 mi) to the south of Hanoi in northern Vietnam later that day.
Mirinae subsequently weakened gradually over northern Vietnam, before it was last noted during July 28, as it dissipated to the north of Hanoi.
