Question: How many hours did the storm which surpassed Typhoon Nora in 2015, grow from a tropical storm to a Category 5 hurricane?

Hurricane Wilma was the most intense tropical cyclone ever recorded in the Atlantic basin, as well as the most intense recorded in the western hemisphere until Hurricane Patricia in 2015.  Part of the record-breaking 2005 Atlantic hurricane season, which included three of the top ten most intense Atlantic hurricanes ever (along with #4 Rita and #7 Katrina), Wilma was the twenty-second storm, thirteenth hurricane, sixth major hurricane, fourth Category 5 hurricane, and second-most destructive hurricane of the 2005 season.  A tropical depression formed in the Caribbean Sea near Jamaica on October 15, headed westward, and two days later intensified into a tropical storm which turned abruptly southward and was named "Wilma".  Wilma continued to strengthen, and eventually became a hurricane on October 18.  Shortly thereafter, explosive intensification occurred, and in only 24 hours, Wilma became a Category 5 hurricane with wind speeds of 185 mph . <SEP> Typhoon Nora was the fourth-most intense tropical cyclone on record.  Originating from an area of low pressure over the western Pacific, Nora was first identified as a tropical depression on October 2, 1973.  Tracking generally westward, the system gradually intensified, attaining typhoon status the following evening.  After turning northwestward, the typhoon underwent a period of rapid intensification, during which its central pressure decreased by 77 mb (hPa; 2.27 inHg) in 24 hours.  The typhoon subsequently weakened and turned northwestward as it approached the Philippines.  After brushing Luzon on October 7, the system passed south of Taiwan and ultimately made landfall in China on October 10.  Once onshore, Nora quickly weakened and dissipated the following day.  At the end of this phase, Nora peaked with winds of 295 km/h (185 mph) and a pressure of 877 mb (hPa; 25.91 inHg), making it the most-intense tropical cyclone on record (alongside Typhoon Ida in 1958) at the time; however, this pressure has since been surpassed by two other typhoons and one hurricane. <SEP> 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. <SEP> Typhoon Elsie, known in the Philippines as Typhoon Tasing, was one of the most intense known tropical cyclones to make landfall in the Philippines.  A powerful Category 5 super typhoon, Elsie formed out of a tropical disturbance on October 13, 1989, and initially moved relatively slowly in an area of weak steering currents.  On October 15, the storm underwent a period of rapid intensification, attaining an intensity that corresponds to a Category 3 hurricane on the Saffir–Simpson Hurricane Scale.  After taking a due west track towards the northern Philippines, the storm intensified further, becoming a Category 5 super typhoon hours before making landfall in Luzon.  After moving inland, the typhoon rapidly weakened to a tropical storm.  Once back over water in the South China Sea, wind shear prevented re-intensifcation.  Elsie eventually made landfall in Vietnam on October 22 and dissipated the following day over Laos.
