Typhoon Dolphin (2026)
Pacific typhoon in 2026
From Wikipedia, the free encyclopedia
Typhoon Dolphin[nb 1] is an active typhoon currently affecting East China. The thirteenth named storm, fifth typhoon and third violent typhoon of the 2026 Pacific typhoon season, Dolphin originated from a disturbance near the International Date Line in the Central Pacific in mid-July. Initially monitored by the Central Pacific Hurricane Center (CPHC), it crossed the International Date Line a week later, with the Japan Meteorological Agency (JMA) recognizing it as a tropical depression during the late hours of July 26. The United States' Joint Typhoon Warning Center (JTWC) followed suit the following day, designating it as 12W; a few hours later, both agencies upgraded it to a tropical storm, with the former giving it the name Dolphin.

Extratropical cyclone, remnant low, tropical disturbance, or monsoon depression
On July 19, the Central Pacific Hurricane Center began monitoring a disturbance south of the Hawaiian Islands. When the disturbance had a high 90% chance of development in the next two days, it was designated Invest 92C.[3] Later on July 26, the disturbance crossed into the Western Pacific, and the JMA classified the system as a tropical depression upon crossover.[citation needed] The following day at midnight, The JTWC upgraded the disturbance to a tropical depression, designating it as 12W,[4] upgraded by the JMA to a tropical storm shortly after, and received its current name Dolphin.[5] Almost immediately after its nomenclature, Dolphin began a period of rapid intensification, to an extent not seen since Typhoon Noru,[6] quickly becoming a typhoon and reaching a Category 4-equivalent initial peak intensity on the Saffir–Simpson scale on July 28, before its intensification was stunted by an eyewall replacement cycle.[citation needed] After finishing, Dolphin resumed intensifying once again, reaching super typhoon status the following day.[citation needed] Soon after reaching Category 5 strength on the Saffir–Simpson scale, Dolphin started undergoing a second eyewall replacement cycle, temporarily halting further development of the storm.[7] Dolphin continued moving westward which it started slowly weakening to a Category 2 equivalent typhoon after 3 days. Next, Dolphin regained intensity as Category 3 typhoon. On August 5th, Dolphin started weaking again shortly to a Category-1 equivalent typhoon with 1-minute sustained winds of 90mph.[citation needed] After that, Dolphin passed the Ryukyu Islands and made a direct landfall over Kume Island. Dolphin soon made landfall in China near the city of Wenzhou.[citation needed]
Preparations
Japan
The Japan Meteorological Agency (JMA) warned of strong winds, heavy rainfall, landslides, and flooding due to the effects of Dolphin.[8] Heavy rainfall warnings were issued for the Daitō Islands as the typhoon closely approached.[9] Level 4 heavy rainfall warnings were also issued for Ogimi, Higashi, and Nakijin. Level 4 landslide warnings were issued for the same areas as well as Kunigami and Motobu. A Level 4 storm surge warning was posted for Kumejima, as well.[10]
More than 260,000 people in Kagoshima and Okinawa prefectures were advised to evacuate. The typhoon was expected to affect parts of Kumamoto Prefecture impacted by a magnitude 7.1 earthquake the previous week. More than 6,700 residents remained in shelters at the time of Dolphin's arrival.[11] Residents in Kumamoto Prefecture covered roofs damage by the earthquake in plastic sheets. More than 500 flights were cancelled due to the storm, with Naha Airport cancelling all its flights on August 7.[12] Toyota ceased operations at nine factories across Japan over concerns about shipping disruptions.[13] All bus companies on the island of Okinawa suspended operations as the typhoon approached.[14] The Okinawa Urban Monorail also suspended operations for the duration of the typhoon.[15] The city government of Naha opened seven temporary storm shelters.[16] About 240 people evacuated to storm shelters prior to the storm across Okinawa Prefecture.[10]
China
China Meteorological Administration (CMA) issued a yellow typhoon warning for part of the country's east coast as Dolphin approached, and updated it to red on the noon of August 9.[17][18] Gale-force winds were expected to impact the waters of the East China Sea and the Bashi Channel, as well as coastal areas of Zhejiang and Fujian.[19]
The provincial government of Zhejiang prepared 15 tow boats for emergencies. A total of 162 ferry routes and 193 water construction projects were halted for the duration of the typhoon. A total of 474 ships were also docked for the storm. Seaside tourists and sports activities in Ningbo were cancelled. The government of Fujian Province declared a Level 4 emergency response which advised all communities to dock fishing vessels and ferries and to secure offshore wind power platforms. Safety inspections, evacuations of high-risk zones, and the gathering of emergency resources were also required through the order.[20] Major delays occurred as ports in China closed in preparation for Dolphin. Container operations were suspended at the Port of Shanghai. Temporary port suspensions were also expected to take place in Ningbo.[21]
The government of China used the arrival of Dolphin to test new technology for typhoons. This included the use of artificial intelligence in forecasting systems at the National Marine Environmental Forecasting Centre which were used to give long-range forecasts for the storm. Drones were also deployed to aid in preparations in coastal provinces.[20]
Philippines
Despite the system remaining outside the Philippine Area of Responsibility (PAR), rainfall warnings were put in place as the system enhanced the southwest monsoon.[22][23] Heavy rainfall warnings were put in place over Bataan, Occidental Mindoro, and Zambales, while multiple provinces plus Metro Manila were put under an orange warning.[24]
Impact
Japan
In Japan, Dolphin reached maximum wind speeds of 162 km/h (101 mph), with Okinawa and Amami Islands among the most affected regions; Naha Airport of Okinawa suspended all flights on August 7.[12]
Taiwan
Taiwan was hit with heavy rainstorms on August 7-8, with citizens of Taipei reporting "toppled trees, downed scaffolding and collapsed construction fencing", and Tamsui District reporting blown-off roofs.[25] One the morning of August 9, Taiwan suspended all ferry routes and issued about 200 flight cancellations; its Central Weather Administration reported a maximum sustained wind speed of 119 km/h (74 mph) on 11 a.m., stating it to be about 350 kilometers north-northeast of Taipei and moving West.[26]
China
In Shanghai, the Shanghai Ferry suspended all services on August 8[27], and all coastal tourist destinations in Fengxian District[28] and a number of parks[29] were temporarily closed. More than 1,300 flights were cancelled on August 9, and around 300,000 people in surrounding regions were evacuated in preparation.[30] Shanghai Disney and Disneytown also closed beginning that night[31]. Numerous metro lines either completely or partially stopped operation, with more closing down on August 10[27][32].
In Zhejiang, Ningbo Lishe International Airport suspended all flights.[12]
Philippines
More than 500 passengers were stranded across 28 ports due to rough conditions brought on by the southwest monsoon that was intensified by Dolphin.[33] Torrential rains caused waist-deep flooding in low-lying communities and areas near creeks in Quezon City. Several other neighborhoods in Manila and western Philippines also experienced flooding.[34] The Malacañan Palace announced sweeping suspensions on classes and work in government offices in Metro Manila and 15 other provinces due to continuing heavy rains by the typhoon's enhancement of the southwest moonsoon.[35]
