On 00:00 UTC of June 19, both the Fleet Weather Center of Guam and China Meteorological Agency started to monitor a tropical depression that developed in the Philippine Sea to the east of Visayas in the Philippines. [1] [2] It has a pressure of 1006 mbar at that time. [1] It started to move towards the northwest, rounding a ridge of high-pressure. [1] It remained a tropical depression while nearing the coastline of Quezon and roughly 3 hours later, the CMA upgraded the system to a tropical storm near Cagayan Province; however, the Fleet Center didn't followed suit until on 12:00 UTC of the next day. [1] [3] The former provided the name Dinah on the intensifying system. [1] This time, it moved to the north with its closest approach to the country is estimated at 250 km to the northeast of Santa Ana, Cagayan. [1] It started to slowly intensify, while nearing the coast of Taiwan. [1] [3] On 18:00 UTC of June 22, both the Fleet Center upgraded the system to a minimal typhoon, as it started to curve towards the northwest. [1] [3] The CMA also upgraded the system, three hours later. [1] Also at this time, Dinah passed through the Nansei Islands, while at peak intensity of 120 km/h (75 mph) and a minimum barometric pressure of 960 mbar; however, the CMA had a higher estimates of 160 km/h (100 mph), equivalent to a Category 2 typhoon. [1] [2] [3] Shortly after its peak, Dinah started to weaken, being downgraded to a tropical storm by the Fleet Center and CMA on 15:00 and 21:00 UTC of the same day, respectively. [1] On the next day, the storm started to interact with Japan as it moved to the northeast, passing near Shikoku before making landfall through the southern part of Kii Peninsula on 20:00 UTC. [2] [1] [4] 3 hours later, Dinah passed to the Kumano Sea, before crossing the coast near Lake Hamana in Shizuoka Prefecture. [2] Early the next day, it passed near Tokyo before moving out to the Pacific Ocean on the afternoon, just before starting its extratropical transition. [2] [1] It began to move to the east at this time, and on 15:00 UTC of June 25, it fully became extratropical, far west of Hawaii. [1] The system began to accelerate to the north, until it was last noted on 18:00 UTC of the next day. [1]

Impact

Philippines

As Dinah skirted the northeastern part of the country, streets near its capital Manila were submerged in one-to-two feet of floodwaters. [5] [6] Due to the sparse coverage of the typhoon, the exact damages, fatalities and the aftermath were unknown.

Japan

Despite Dinah, not a typhoon when it approached the Japanese islands, its effects were significant. [7] Irozaki in Shizuoka Prefecture recorded the highest instantaneous wind speed of 48.6 meters per second, while Omaezaki recorded the highest instantaneous wind speed of 43.8 meters per second, all on June 23. [2] In some areas, such as southern Kyushu, eastern Shikoku, the Kii Peninsula, and Izu Peninsula, rainfalls reached 200-350 mm. [8] Thus, typhoon heavily damaged areas west of Kanto, mainly in Shizuoka Prefecture. [2] The short rainfall in Tokushima Prefecture was between 100 and 200 mm and the hourly rainfall in its city was 55.8 mm, which was June's highest record. [9] [3] [10]

A total of 65 individuals were killed, mainly due to the landslides induced by heavy rainfall from the storm. [11] A huge mudslide trapped 53 persons at it; however, 42 were rescued by authorities and the other 11 was declared dead. [5] In Fukui Prefecture, another landslide wiped out a house, leaving 9 dead. [5] Nearly 13,000 acres of farmland were also destroyed by flash floods and over 25,000 households and wards were also damaged and/or flooded. [5] [12] The typhoon was later declared a significant disaster to the country. [4]
