Early on July 22, an area of low pressure formed to the east of Philippines. The system gradually drifted west over the next few days and late on July 24, the Joint Typhoon Warning Center Started Monitoring the system as a Tropical Depression.

Early the next day, the Japan Meteorological Agency (JMA) upgraded the area of low pressure into a Tropical Depression. A few hours later, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) started monitoring the system as a Tropical Depression and named it ‘Juaning’.

The system continued to drift westwards and strengthened rapidly, that on midnight, that day, the JMA furhter upgraded the system into a Tropical Storm, naming it Nock-Ten. Early on July 27, the JMA reported that Nock-ten continued to strengthen and upgraded it into a Severe Tropical Storm.

A few hours later, the JTWC reported that Nock-ten rapidly intensified to a category 1 typhoon and made its landfall over northern Aurora (province) and started weakening. Later the same day, the JMA reported that Nock-ten had exited the Luzon island at Candon maintaining severe tropical storm strength.

However, overnight, the storm rapidly weakened and the JMA downgraded it into a minor tropical storm the next day. However, on July 29, the storm gradually regained strength and approached south China coast at Qionghai, China. Later that day, the storm strengthened over land and headed north towards Hainan’s provincial capital region Haikou. Over the next day, the storm drifted to the west and made landfall over Northern Vietnam. The storm weakened rapidly and at midnight that day, the JMA, issuing their final warning on the system, downgraded it into a tropical low.

The provinces of Albay and Camarines were reported to be completely flooded by the rain. Minor damage to rice crops was reported. More heavy rains were expected throughout the day as the system had exited land into the South China Sea and would soon start reintensifying. The number of missing was also pushed up to 31 after 25 crewmembers of a fishing boat were reported missing when their fishing boat was caught in the storm off Masbate.  In Northern Luzon, Nock-ten poured down heavy rainfall becoming widespread flooding in the area. The national roads were impassable and landslides were also reported. About 26 domestic flights were cancelled from July 26 to 27 due to heavy rains and strong winds.
