How many hours did the storm which surpassed Typhoon Nora in 2015, grow from a tropical storm to a Category 5 hurricane?
Hurricane Patricia Hurricane Patricia was the second-most intense tropical cyclone on record worldwide, behind Typhoon Tip in 1979, with a minimum atmospheric pressure of 872 mbar (hPa; 25.75 inHg). Originating from a sprawling disturbance near the Gulf of Tehuantepec, south of Mexico, in mid-October 2015, Patricia was first classified a tropical depression on October 20. Initial development was slow, with only modest strengthening within the first day of its classification. The system later became a tropical storm and was named Patricia, the twenty-fourth named storm of the annual hurricane season. Exceptionally favorable environmental conditions fueled explosive intensification on October 22. A well-defined eye developed within an intense central dense overcast and Patricia grew from a tropical storm to a Category 5 hurricane in just 24 hours—a near-record pace. On October 23, the hurricane achieved its record peak intensity with maximum sustained winds of 215 mph (345 km/h). This made it the most intense tropical cyclone on record in the Western Hemisphere, and the strongest globally in terms of 1-minute maximum sustained winds.
Typhoon Cimaron (2006) Typhoon Cimaron, known in the Philippines as Typhoon Paeng, was the most intense tropical cyclone to strike the Philippine island of Luzon since Typhoon Zeb in 1998. Originating from a tropical depression on October 25, Cimaron developed within an environment strongly favoring tropical cyclogenesis east of the Philippines. On October 28, the system underwent rapid intensification, culminating in attaining its peak strength with winds of 185 km/h (115 mph). Estimates from the Joint Typhoon Warning Center ranked the system as a Category 5-equivalent super typhoon with one-minute sustained winds of 260 km/h (160 mph), though this is argued to have underrepresented the typhoon's strength. The system moved ashore near Casiguran, Aurora in northern Luzon at peak strength. Crossing the island, Cimaron emerged over the South China Sea where conditions allowed for temporary reorganization. After becoming nearly stationary on November 1, the typhoon executed a tight anti-cyclonic loop and rapidly weakened. The storm degraded to a tropical depression on November 4 before dissipating three days later off the coast of Vietnam.
