The remnants of Atlantic Tropical Depression Nine tracked westward across the Caribbean Sea, entering the Pacific Ocean on September 3. It slowly developed, and organized into a tropical depression on September 8. It strengthened into a tropical storm on September 10, thus earning the name Octave . After strengthening into a hurricane the next day, Octave started to steadily intensify en route to a peak as a Category 4 hurricane of the Saffir–Simpson Hurricane Scale. After reaching peak winds of 135 mph (215 km/h) on September 13, Octave moved into a region of cooler waters. The hurricane weakened into a tropical storm on September 14 and a tropical depression the next day before dissipating on September 16. The remnants impacted California and Arizona. The remnants of the storm brought moderate rainfall to parts of California and Arizona as well as three F0 tornadoes.
