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 Bopha Typhoon Bopha, known in the Philippines as Typhoon Pablo, was the strongest tropical cyclone to ever hit the southern Philippine island of Mindanao, making landfall as a Category 5 super typhoon with winds of 175 mph (280 km/h). Bopha originated unusually close to the equator, becoming the second-most southerly Category 5 super typhoon, reaching a minimum latitude of 7.4°N on December 3, 2012. Only Typhoon Louise of 1964 came closer to the equator at this strength, at 7.3°N. After first hitting Palau, where it destroyed houses, disrupted communications and caused power outages, flooding and uprooted trees, Bopha made landfall late on December 3 on Mindanao, an island that had been devastated by the much weaker Tropical Storm Washi in December 2011. The storm caused widespread destruction on Mindanao, leaving thousands of people homeless and more than 600 fatalities.
