Typhoon Mawar, known in the Philippines as Super Typhoon Betty, was one of the strongest Northern Hemisphere tropical cyclones on record in the month of May, and the strongest tropical cyclone worldwide in 2023.[1] The name "Mawar" means Rose in Indonesia. The second named storm, the first typhoon and the first super typhoon of the 2023 Pacific typhoon season, Mawar originated from an area of low pressure south-southwest of Chuuk Lagoon that developed into a tropical depression on May 19. It fluctuated in intensity and became a tropical storm, after which it intensified into a Category 4-equivalent super typhoon on the Saffir–Simpson hurricane wind scale. It then underwent an eyewall replacement cycle, then reintensified to attain 1-minute sustained winds of 305 km/h (190 mph) according to the JTWC, becoming a Category 5-equivalent super typhoon. Mawar weakened slightly as it moved around the southwestern edge of the subtropical high that made it steer north of the Philippines and then east of Taiwan. Mawar traversed the Okinawa Islands as a tropical storm, then transitioned into an extratropical cyclone as it moved northeastward out to sea, where it later dissipated east of Kamchatka Peninsula.

Typhoon Mawar passed north of Guam as a Category 4-equivalent typhoon on May 24, bringing hurricane-force winds and heavy rain marking as the strongest storm to affect the island since Typhoon Pongsona in 2002.[2][3] U.S. President Joe Biden declared Guam a major disaster area on May 27, enabling the distribution of federal funds. Two men are presumed dead after going missing in the waters off Guam; additionally, one death related to the storm has been reported in Taiwan. Mawar caused one death, one minor injury, and damage worth ₱201,696 (US$3,584) as it passed close to the eastern Philippines.[4] Heavy rain in parts of Japan killed two people and left four people missing.[5] At least 8,900 homes experienced power outages in Japan. Total damages from Mawar are estimated to reach US$4.3 billion.[6]
