Super Typhoon Kenneth: A Retrospective Analysis of the 2023 Storm
Formation and Meteorological History
Super Typhoon Kenneth formed in the western Pacific Ocean in late May 2023. The storm rapidly intensified from a tropical depression to a super typhoon within 48 hours, fueled by warm sea surface temperatures and low wind shear. The Joint Typhoon Warning Center (JTWC) reported peak sustained winds of 175 mph (280 km/h), equivalent to a Category 5 hurricane on the Saffir-Simpson scale. Kenneth's eye passed just north of Guam on May 24, 2023, bringing catastrophic conditions to the island.
