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.
Hurricane Bret Hurricane Bret was the first of five Category 4 hurricanes that developed during the 1999 Atlantic hurricane season and the first tropical cyclone since Hurricane Jerry in 1989 to make landfall in Texas at hurricane intensity. Forming from a tropical wave on August 18, Bret slowly organized within weak steering currents in the Bay of Campeche. By August 20, the storm began to track northward and underwent rapid intensification on August 21. After this period of strengthening, Bret attained its peak intensity with winds of 145 mph (230 km/h) and a barometric pressure of 944 mbar (hPa; 27.88 inHg). Later that day, the storm weakened to a Category 3 hurricane and made landfall on Padre Island, Texas. Shortly thereafter, the storm weakened further, becoming a tropical depression 24 hours after moving inland. The remnants of the storm eventually dissipated early on August 26 over northern Mexico.
