Typhoon Cimaron was a typhoon that caused minimal impacts in the Mariana Islands and Japan in August 2018. The twenty-third depression, twenty-first named storm, eleventh severe tropical storm, and seventh typhoon of the 2018 Pacific typhoon season, Cimaron developed from a tropical depression near the Marshall Islands on August 16. The depression soon became Tropical Storm Cimaron on August 18. Cimaron gradually intensified into a typhoon on August 21, and rapidly reached its peak intensity the next day. Cimaron then weakened before making two landfalls in Japan as a Category 1 typhoon on August 23. Cimaron continued to weaken until it became an extratropical cyclone and dissipated on August 24.
