Typhoon Lionrock
Typhoon Lionrock, known in the Philippines as Typhoon Dindo, was a large, powerful, long-lived and erratic tropical cyclone which caused significant flooding and casualties in North Korea and Japan in late August 2016. It was the tenth named storm and was the third typhoon of the 2016 Pacific typhoon season. Damages recorded after the season were recorded about US$3.93 billion.
The system that was to become Typhoon Lionrock was first noted as a subtropical disturbance on August 15, while it was located about 585 km (365 mi) to the west of Wake Island. At this time the disturbance had a broad and poorly organized low level circulation centre, which had some shallow bands of atmospheric convection wrapping loosely around it. It was located within a marginal environment for further development and was predicted to develop further, in association with a developing upper-level low. Over the next day the system moved northwards, while a TUTT Cell created subsidence and high vertical windshear over the system, before it was classified as a tropical depression by the Japan Meteorological Agency during August 16. The depression was subsequently classified as subtropical by the United States Joint Typhoon Warning Center during August 17, as its structure was asymmetric, with deep convection displaced to the north and east of the system's low level circulation centre.
Lionrock entered the Philippine Area of Responsibility on August 25, 2016, and PAGASA assigned Dindo as the local name for Lionrock. On August 29, Lionrock turned towards the northwest due to a high pressure system located east of Japan, putting it on an unprecedented path towards the northeastern region of the country. Right before weakening into a severe tropical storm at 18:00 JST (09:00 UTC) on August 30, Lionrock made landfall near Ōfunato, a city in Iwate Prefecture, Japan with winds of 75 mph (121 km/h). This makes Lionrock the first tropical cyclone to make landfall over the Pacific coast of the Tōhoku region of Japan since the Japan Meteorological Agency began record-keeping in 1951.
Lionrock's track was unusual due to the fact that the storm approached Japan from the southeast and made landfall along the east coast of the country. Most typhoons that hit Japan approach from the south or the southwest before moving northward across the archipelago. In fact, the only other storm to take a similar track was Typhoon Mac in 1989, which also approached from the southeast and struck Japan's Kantō region along its east coast.
Japan's Prime Minister Shinzō Abe left a Japan-African development conference in Nairobi, Kenya early due to the threat of flight cancellations caused by the typhoon. Prior to Lionrock making landfall, a total of 100 flights were cancelled at airports in Tohoku and Hokkaido. Efforts were made to protect the Fukushima Daiichi Nuclear Power Plant from further damage, as it had been severely incapacitated following the 2011 Tōhoku earthquake and tsunami. The amount of water being pumped at the facility was increased in order to minimize the risk of floods, and crane operations were suspended due to the threat of strong winds.
In eastern Russia, a storm warning was announced on 28 August by EMERCOM. All emergency services and troops were on high alert. Local authorities were informed on emergency procedures.
North Korea's Early Warning and Evacuation system was activated ahead of the storm, causing 44,000 people in flood-prone areas to be evacuated in North Hamgyong Province.
Upon making landfall on August 30, Lionrock brought very heavy rainfall, including 13.46 inches (342 mm) at Mount Nukabira, in Hokkaidō Prefecture, and 8.78 inches (223 mm) in Orito in Iwate Prefecture. In addition, a maximum wind gust of 69 mph (111 km/h) was recorded in Ishinomaki, and a 66 mph (106 km/h) wind gust was measured in Onagawa. Lionrock killed a total of 22 people across Japan, including 19 people in the town of Iwaizumi in Iwate Prefecture. Nine people drowned in a nursing home in Iwaizumi after a river burst its banks. In addition, there were at least three fatalities on the northern Japanese island Hokkaidō. Damage due to flooding were standing at JP¥282 billion (US$2.74 billion).
