Typhoon Bavi, known in the Philippines as Severe Tropical Storm Igme, was a powerful tropical cyclone that made landfall in North Korea in August 2020. The eighth named storm and third typhoon of the 2020 Pacific typhoon season, Bavi formed from a low pressure area depression on August 21 to the north of the Philippines and strengthened into a tropical storm on August 22. Bavi gradually strengthened as it skirted Taiwan and Okinawa, and became a typhoon on August 24. Passing over warm waters, Bavi turned to northwest and reached its peak intensity near Jeju Island on August 26. Thereafter, increasing wind shear and cooler waters caused Bavi to quickly weaken. Bavi made landfall in North Korea on August 27, and became an extratropical cyclone shortly thereafter.

Bavi caused minimal damage in portions of South Korea and Japan, but caused widespread structural damage and flooding in North Korea. It was the first storm in two weeks span to affect Korea. Others were Maysak and Haishen.

On August 19, the JTWC began monitoring a broad area of low pressure situated a couple hundred miles northeast of the Philippine archipelago. By the next day, the system rapidly organised, and the JTWC subsequently issued a Tropical Cyclone Formation Alert (TCFA), and on August 21, the area of low pressure organized into Tropical Depression 09W.^[1] At 15:00 UTC, the PAGASA named the system "Igme" and issued a severe weather bulletin for it.^[2] By the next day the system had intensified into a tropical storm, and the JMA gave it the name Bavi and upgraded it, with the JTWC doing the same.^[3] Favorable conditions allowed Bavi to rapidly intensify, and by 12:00 UTC on August 22, the system became a severe tropical storm. The system left the Philippine Area of Responsibility on the same day.^[4] Bavi's period of rapid intensification was brief, with its intensification significantly slowed on August 23.

On August 24, Bavi was upgraded into a typhoon by the JTWC as it continued to slowly intensify. Later on that day, it became a Category 2 typhoon, with it becoming a Category 3 typhoon on the next day. As Bavi moved closer to the Korean peninsula, one person died in Jeju Island on August 25.^[5] Soon afterwards, as Bavi moved northwards into very hostile conditions and high wind shear, which caused Bavi to rapidly weaken. Wind shear was still high and the storm started extratropical transition. Around 00:30 UTC on August 27, a weakened Bavi made landfall over North Pyongan Province, North Korea as a minimal typhoon.^[6] Both the JMA and the JTWC issued their final advisory on Bavi a few hours later as it became an extratropical cyclone over Northeastern China.
