Typhoon Sinlaku quickly grew into a very powerful Category 5 storm, with peak winds of about 185 mph on 12 April 2026, making it the strongest cyclone in the world in 2026 so far. It first formed on 9 April 2026 in the western North Pacific. Very warm ocean waters and calm upper-level winds helped the storm strengthen extremely fast in a short amount of time. After forming, Sinlaku moved west-northwest through the Federated States of Micronesia, causing serious damage, and then passed near the Northern Mariana Islands. The storm later turned north and changed into a non-tropical (extratropical) system by 19 April 2026. While its strongest winds weakened, the storm spread out and continued to produce strong, widespread winds. On 19 April, the the Joint Typhoon Warning Centre (JTWC) issued its final warning, stating that Sinlaku was weakening but still dangerous due to large areas of gale-force winds.
