Typhoon Goni, known in the Philippines as Typhoon Ineng, was a strong tropical cyclone that impacted many countries during late August 2015. The fifteenth named storm of the annual typhoon season, Goni was first seen as a weak tropical disturbance from a cloud cluster several nautical miles east southeast of Guam. The system intensified into a tropical depression on August 13, then a named storm by the next day. Similar to the output of Typhoon Soudelor earlier in the month, Goni impacted the Mariana Islands before gathering strength and intensifying into the ninth typhoon.

On August 13, the JMA started to monitor a tropical depression that had developed, about 685 km (425 mi) to the southeast of Hagåtña, Guam.[1] Behind Goni was another depression. It later became super typhoon Atsani, in which they became the "double-threat" pair of typhoons. By the next day, the depression started to organize and was designated as 16W by the JTWC.[2] Several hours later, deep convection had improved and has covered its LLCC and both agencies upgraded 16W to a tropical storm, naming it Goni.[3][4] During the night of August 15, the JMA upgraded Goni to a severe tropical storm as windshear started to calm whilst deep convective banding wrapping into its circulation.[5][6] By the next day, satellite imagery depicts a developing eye with an improved tightly-curved banding which upper-level analysis reveals that low shear and an improving environment.[7] Goni intensified into a typhoon by both agencies a few hours later.[8][9]

Early on August 17, satellite imagery depicted a small-pinhole eye as Goni underwent rapid intensification and was upgraded rapidly to a Category 4 typhoon and reached its first peak intensity.[10] Slightly thinning convective banding and low to moderate wind shear caused Goni to weaken to a Category 3 typhoon.[11] Goni maintained that intensity while moving westward and entered the Philippine Area of Responsibility which PAGASA gave it the local name Ineng,[12] until on August 19, Goni entered an area of favorable environments. Goni had maintained an overall convective signature with tightly-curved banding wrapping into a 28 nautical-mile eye.[13] The JTWC later re-upgraded Goni back at Category 4 typhoon status early on August 20 as it neared the northeastern Philippine coast. Rapidly weakening soon after, Goni executed a sharp north turn. Then as it turned northeastwards, Goni re-intensified for the third time into a Category 4 typhoon mid-day on August 23.

Typhoon Goni quickly passed through Uki, Kumamoto after 20:00 UTC and made landfall over Arao, Kumamoto after 21:00 UTC on August 24 (06:00 JST on August 25)[14][15] The system arrived in the Sea of Japan as a typhoon early on the next day and weakened into a severe tropical storm at 09:00 UTC.[16] Goni moved northeast then transitioned into extratropical cyclone, as the JTWC and JMA issued their final advisories. Goni's remnants later affected Northeast China and Russia.

Preparations and impact

Mariana Islands

Just nearly two weeks after Soudelor hit the area, the weather service of Guam started to warn residents within the islands to prepare from Tropical Storm Goni. “A lot of the structures that got wiped out by Soudelor, they haven’t had time to rebuild anything yet.” was stated from a forecaster of the National Weather Service of Guam.[17]

Philippines

The PAGASA started issuing advisories on Ineng (Goni) as it entered the Philippine area of Responsibility on August 18.[18] On August 19, PAGASA issued Public Storm Signal #1 and 2 over Batanes and Isabela. The National Disaster Risk Reduction and Management Council was placed on blue alert in preparation for the typhoon.[19] PSWS #3 further raised in those same places on August 20.[20] In nearly the same time, NDRRMC raised from Blue to Red Alert in their area (Under Red Alert status, the NDRRMC continuously monitors and disseminates weather advisories, 24-hour public weather forecasts, gale warnings, and general flood advisories to all regional DRRMCs (RDRRMCs) and Office of Civil Defense regional centers (OCDRCs)). According to the situation report, the Department of Social Welfare and Development (DSWD) has also prepositioned a total of PHP 47,551,086.98 standby funds, 369,199 food packs, and PHP 247,772,538.48 worth of food and non-food items, beginning on August 14, to be utilized in the aftermath of Typhoon Ineng.[21][22] Classes from kinder to high school over in Cagayan province were suspended on August 19.[21][23]

According to the NDRRMC, a total of 33 people are reported dead so far as of September 8, and total damages from both infrastructure and agriculture were amounted to P4.4 billion ($94.3 million USD).[24] The name Ineng was not retired from its naming lists.

Taiwan

Heavy rain hit the capital as the typhoon moved up the coast.

Japan

Five people were injured when Goni passed over Ishigaki Island on August 23.[25] One death has been attributed to high waves as the storm moved towards the mainland. According to NHK, a 66-year-old man drowned after falling from a fishing boat off of Miyazaki Prefecture on the southern island of Kyushu on August 24.[26] Damage to agriculture in Okinawa is estimated at ¥780 million (US$6.5 million).[27] Agriculture damage in Fukuoka Prefecture reached ¥1.6 billion (US$13.3 million).[28] Total damage in Kagoshima Prefecture reached ¥2.1 billion (US$17.5 million).[29] Agricultural, forestry, and fisheries losses in Kumamoto Prefecture amounted to ¥4.1 billion (US$34.1 million).[30] Agricultural losses exceeded ¥600 million (US$5 million) in Oita Prefecture and reached ¥512 million (US$4.3 million) in Saga Prefecture.[31][32]

South Korea

The country went on "alert" on August 25, 2015. There has been no recorded deaths or damages taken. Heavy rain has been observed, an average of 30 millimeters an hour.[33]

Russia

The extratropical remnants of Typhoon Goni brought damaging winds and heavy rains to Primorsky Krai in the Russian Far East. Some areas received more than two months' rain during the storm's passage, resulting in widespread flooding.[34] Approximately 9,500 people were directly affected by the storm, mostly in Ussuriysk. More than 300 buildings sustained damage.[35] Agriculture sustained substantial impact, with 88,300 hectares of crops damaged or destroyed; losses in the sector reached 2.4 billion rubles (US$35.5 million).[34] Total damage from the storm amounted to 8 billion rubles (US$118.3 million).[35]
