Typhoon Jebi, known in the Philippines as Typhoon Maymay, is currently a weakening extratropical cyclone over Sakha Republic, Russia. Jebi was tied as the most intense tropical cyclone in the Northern Hemisphere of 2018,[1] and is considered to be the strongest typhoon to strike Japan since Typhoon Yancy in 1993.[2] Jebi formed as the twenty-first named storm of the annual typhoon season on August 28. It rapidly intensified into a typhoon on the following day and reached peak intensity on August 31 after striking the Northern Mariana Islands. Jebi initiated a slow weakening trend on September 2 and made landfall over Shikoku and then the Kansai region of Japan as a very strong typhoon on September 4.

A low-pressure area formed near the Marshall Islands early on August 25.[3] It remained devoid of a low-level circulation center (LLCC) next day;[4] however, the system developed further on August 27 that both of the Japan Meteorological Agency (JMA) and the Joint Typhoon Warning Center upgraded it to a tropical depression,[5] based on persistent deep convection wrapping into a consolidating LLCC.[6] Early on August 28, the system was upgraded to a tropical storm with an international name Jebi assigned by JMA.[7] On the 29th of August, The JMA upgraded the storm to a typhoon after it developed an eye with a central dense overcast, and underwent rapid intensification, and then intensified into the third super typhoon and also the second Category 5 typhoon of the season.

On September 4, Jebi made its first landfall over the southern part of Tokushima Prefecture at around 12:00 JST (03:00 UTC),[8] crossed the Osaka Bay, made its second landfall over Kobe, Hyōgo Prefecture at around 14:00 JST (05:00 UTC),[9] and moved over Osaka and Kyoto prefectures before ultimately emerging into the Sea of Japan shortly after 15:00 JST (06:00 UTC).[10] Simultaneously, a cold front has formed southwest of the typhoon, indicating the beginning of an extratropical transition.[11] On September 5, after JTWC issued a final warning at 00:00 JST (15:00 UTC),[12] Jebi was downgraded to a severe tropical storm at 03:00 JST (18:00 UTC) when it was located near the Shakotan Peninsula of Hokkaido.[13] The storm completely transitioned into a storm-force extratropical cyclone off the coast of Samarga, Primorsky Krai, Russia shorly before 10:00 VLAT (09:00 JST, or 00:00 UTC); soon, the former typhoon made its third landfall over the region with 10-minute maximum sustained winds at 100 km/h (65 mph).[14]

Impact

Typhoon Jebi over the Osaka Bay on September 4

Taiwan

Typhoon Jebi brought large waves to the east coast of Taiwan on September 2 and 3 when it recurved northward east of the Ryukyu Islands. On September 2, at the Mystery Beach in Nan'ao Township, Yilan County, deadly incidents involving large waves were reported on September 2, causing 5 fatalities;[15] the other one death also occurred at the Neipi Beach in Su'ao Township.[16] In the next morning, also at the Neipi Beach, a middle-aged woman was also swept away by the waves; however, it was reported that she walked into the waves and stayed in the ocean, presumed to be a suicidal action.[17]

Japan

Typhoon Jebi was the most intense tropical cyclone to make landfall over Japan since Typhoon Yancy in 1993, causing a significant disaster in the Kansai region. At least 11 deaths and more than 600 injuries were reported across the region. Kansai International Airport, one of the most important transport hubs in Japan, was completely shut down because of flooding. A fuel tanker rammed into Sky Gate Bridge R and severely damaged it, cutting off the linking road to the airport and leaving more than 3,000 travelers and employees stranded.[18]
