Typhoon Surigae, known in the Philippines as Super Typhoon Bising, was the strongest tropical cyclone worldwide in 2021 and the most powerful to form before the month of May in the Northern Hemisphere in any calendar year.[1]: S247 [2][3] The second named storm, first typhoon and first super typhoon of the 2021 Pacific typhoon season, Surigae originated from a low-pressure area south of the Micronesian island of Woleai. The low organized into a tropical depression on April 12. At 18:00 UTC that day, it strengthened into a tropical storm and was named Surigae by the Japan Meteorological Agency (JMA). Very favorable environmental conditions then allowed Surigae to begin a bout of rapid intensification after becoming a typhoon on April 15; by April 17, the storm reached its peak intensity with 10-minute sustained winds of 220 km/h (140 mph),[nb 1] 1-minute sustained winds of 315 km/h (195 mph), and a minimum pressure of 895 hPa (26.4 inHg). Afterward, weakening outflow and an eyewall replacement cycle caused Surigae to gradually weaken as its track shifted north-northwestward in the Philippine Sea. Following the eyewall replacement cycle, Surigae became an annular tropical cyclone on April 19, and restrengthened slightly. On April 22, the storm began to rapidly weaken as it accelerated northwestward into unfavorable environmental conditions, transitioning into a subtropical storm the next day. The subtropical system subsequently underwent extratropical transition, which it completed by April 24. Three days later, Surigae's remnant explosively intensified into a bomb cyclone near the Aleutian Islands, attaining hurricane-force winds. Afterward, the system gradually weakened as it turned eastward, crossing the International Date Line on April 30 and fully dissipating that same day.
Surigae is a North Korean word for the black-eared kite. Upon Surigae's naming, watches and warnings were issued for the island of Yap in the Federated States of Micronesia and the islands of Koror and Kayangel in Palau as well. The typhoon left US$4.8 million in damage in Palau after cutting off power and water and destroying infrastructure.[nb 2] Later, warnings were raised for parts of the Philippines as the typhoon moved closer to the nation, with evacuations taking place in eastern regions of the Visayas. The Philippines was battered with heavy rainfall, flooding and strong winds as Surigae passed just offshore. Landslides displaced over 100,000 people in the Bicol Region. The cargo ship LCU Cebu Great Ocean ran aground in the southern Philippines. Overall, Surigae killed at least 10 people and left another eight missing, in addition to causing at least ₱272.8 million (US$5.67 million) in damage in the Philippines.
