Typhoon Tapah, known in the Philippines as Typhoon Nimfa, was a fairly strong tropical cyclone that peaked as a Category 1-equivalent typhoon, causing damages in Japan and South Korea in mid-September 2019. The seventeenth named storm and the seventh typhoon of the 2019 Pacific typhoon season, Tapah formed on September 17 from the remnants of Tropical Depression Marilyn.
On September 17, a tropical depression formed from the remnants of Tropical Depression Marilyn east of Batanes. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) later named the system Nimfa as it entered the Philippine Area of Responsibility (PAR), with the Joint Typhoon Warning Center (JTWC) issuing a medium warning. A non-warning tropical depression in the South China Sea merged with the circulation of Tapah on September 19. Tapah exited the PAR two days later after PAGASA issued its last advisory for it. The storm further intensified as it passed the Ryukyu Islands, upgraded to a typhoon as per the JMA. Later, Tapah weakened into a severe tropical storm, as its wind field diameter expanded. It then began to rapidly weaken, transitioning into an extratropical storm on September 23 at 00:00 UTC. Then, by 18:00 UTC on the same day, the extratropical remnants of Tapah fully dissipated in the Sea of Japan.
JMA issued a red warning for stormy weather and high waves over the coastal Prefectures of central and northern Honshu. Moderate rainfall to locally heavy rainfall was forecasted for the area.
Across the Okinawa and the Miyazaki Prefecture, 21 people were injured and regional authorities had issued evacuation advisories for more than 2,000 people. In addition, media reported that more than 400 flights were canceled and that several railway disruptions and power outages affected around 28,500 buildings. During the passage of Tapah, three people were killed in Japan, and the agricultural damage amounted to ÃÂ¥583 million (US$5.42 million). Damages in South Korea were at â©2.96 billion (US$2.48 million). Though three deaths were reported during the storm, officials said that they were not related to Tapah.
