On June 15, the JTWC started to monitor an area of disturbed weather that was about 1350 km (835 mi), to the southeast of Manila, Philippines. Over the next couple of days the system gradually developed further, before late on June 16, the JMA, JTWC and PAGASA, all reported that the system had developed into a tropical depression, with PAGASA naming it as Egay. Egay continued to develop during June 17 as it moved towards the northeast, and on June 18 the JTWC reported that Egay had intensified into a tropical storm. Late on June 19, the JTWC downgraded Egay to a tropical depression, but they upgraded Egay again to a tropical storm on June 20. Early on June 20, the JTWC downgraded Egay to a tropical depression again. On June 21, the JMA upgraded the system into a tropical storm and named it Haima, with the JTWC following suit on June 22.
During the evening of June 23, the JTWC downgraded Haima to a tropical depression after making landfall in Zhanjiang, Guangdong, China but upgraded it to a tropical storm again on June 24. Early on June 25, Haima became a tropical depression after moving inland in Vietnam. As it made landfall over Hanoi, Vietnam, the JTWC and the Hong Kong Observatory downgraded Haima to a low pressure area.
Early on June 20, and area of low pressure about 760 km (470 miles), east of the Philippines began to be monitored by both the JTWC and JMA. That evening, the JTWC issued a Tropical Cyclone Formation Alert. Soon afterwards, PAGASA upgraded the system into a tropical depression, naming it as "Falcon". At the time of the upgrade, Falcon was about 1000 km (620 miles), east northeast of Cebu City. During the evening of June 21, the JTWC also reported that Falcon had strengthened into a tropical depression. On June 22, both the JTWC and the JMA upgraded Falcon into a tropical storm, and the JMA named it Meari. Meari leaves Philippines with 2 deaths and 5 missing. In the afternoon on June 24, the JMA upgraded Meari to a severe tropical storm as it passed Okinawa, Japan.
On June 26, Meari rapidly moved to the Yellow Sea but slowly passed Weihai, Shandong, China, and then the JMA downgraded Meari to a tropical storm on the same day. On June 27, the JTWC downgraded Meari to a tropical depression before it made landfall in North Korea, and the JMA reported that Meari became a low pressure area later.
Heavy rains from the storm's outer bands triggered significant flooding and landslides in South Korea. At least nine people were killed and three others were reported missing across the country. In North Korea, heavy rains from the storm caused widespread flooding and damage. At least 160 homes were destroyed and 50,000 hectares of crops submerged. Several reports of confirmed fatalities arose but no details on how many were given to news agencies.
Late July 9, 2011, an area of low pressure area formed about 300 km (186 mi) east of Aurora. The center was north of Basco, Batanes. On the morning of July 9, JMA upgraded the low pressure area into a tropical depression and it was 450 km northeast of Cagayan. In the afternoon, PAGASA upgraded the low pressure area into a tropical depression and named it Goring. After moving to Fujian, China, it weakened into an overland low pressure area on the evening on July 10.The remnant low of Goring appears to have redeveloped into a Tropical Depression on July 16
On July 11, both the JMA and JTWC upgraded a tropical disturbance to a tropical depression which was near Minamitorishima. On July 12, both the JMA and JTWC upgraded the system to a tropical storm and named it Ma-on. Early on July 13, the JMA upgraded Ma-on to a severe tropical storm. Late on July 13, both the JMA and the JTWC upgraded Ma-on to a typhoon. After absorbing Tokage, Ma-on reached its peak strength on July 16. The PAGASA named it Ineng on July 17.
As Ma-on was affecting Japan, the JTWC downgraded it to a tropical storm in the evening on July 19. Ma-on made landfall in Tokushima later. The JMA downgraded Ma-on to a severe tropical storm after it made landfall in Wakayama early on July 20. The JTWC downgraded Ma-on to a tropical depression on July 21 and discontinued advisories the following day. The JMA downgraded Ma-on to a tropical storm early on July 23. On July 24, Ma-on weakened into an extratropical cyclone east of the Tōhoku region.
A low pressure area has formed about 740 km north-northwest of Palau. Early on July 14, the JMA upgraded it into a tropical depression, and the JTWC issued a Tropical Cyclone Formation Alert. On July 15, the JMA upgraded the system to a tropical storm and named it Tokage, and the JTWC upgraded it to a tropical depression later. PAGASA also upgraded it to a tropical depression and named it Hanna. Due to the Fujiwhara effect, Typhoon Ma-on, the powerful storm just northeast of Tokage, later weakened Tokage to a tropical depression and completely absorbed it early on July 16.
It can be traced back to a Tropical Depression on July 10, which made landfall over Fujian, China.The remnant low of the weak depression drifted back south, and entered the South China Sea on July 13, and later started to reintensify as it drift back inland, the JMA reported that a low has strengthen into tropical depression as it drifted over Guangdong, China on July 16. On July 17, the depression dissipated completely.
Originally a low pressure area, the JMA reported that a tropical depression formed from it in the Gulf of Tonkin near Guangdong, China on July 16. However, it quickly dissipated after only six hours.
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 has 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.
