Part of the 2024 Pacific hurricane season |
Hurricane Kristy was a powerful tropical cyclone in the eastern Pacific Ocean. The twelfth named storm, fifth hurricane, and third major hurricane of the 2024 Pacific hurricane season, Kristy formed from a trough of low pressure which absorbed the remnants of Atlantic basin Tropical Storm Nadine off the southern coast of Mexico. Through October 22 and October 23, Kristy rapidly intensified to a high-end Category 4 hurricane. Then, after slightly weakening due to an eyewall replacement cycle, Kristy briefly became a Category 5 hurricane on October 24, with maximum sustained winds of 160 mph (260 km/h).
Kristy is the first Category 5 Pacific hurricane in a non-El Niño year since Celia in 2010. Category 5 Pacific hurricanes rarely occur outside of El Niño years, which generally feature unusually favorable conditions for Pacific hurricanes.[1]
Meteorological history
[edit]On October 19, 2024, the National Hurricane Center (NHC) predicted that the future interaction between a Tehuantepecer gap wind event and the remnants of Tropical Storm Nadine from the Atlantic basin would result in the development of a low-pressure area off the coast of southwestern Mexico. This forecast disturbance was marked as having a high likelihood of developing into a tropical cyclone.[2] A trough of low pressure formed within the Gulf of Tehuantepec the following morning tracking westward at 15 mph (24 km/h) away from the Mexican coast.[3] A well-defined center of circulation developed in connection with the disturbance on October 21, accompanied by increasingly organized showers and thunderstorms.[4] The NHC determined that the disturbance had organized into a tropical storm 275 mi (445 km) south-southwest of Acapulco by 21:00 UTC that day based on satellite-derived wind data and subjective satellite intensity estimates, leading to the issuance of advisories on Tropical Storm Kristy.[5][6]
Kristy was in a favorable environment for further development, and soon strengthened to a Category 1 hurricane[7] on October 22 at 21:00 UTC.[8] Kristy then began a period of rapid intensification,[9] and attained an initial peak intensity with maximum sustained winds of 155 mph (250 km/h) just 12 hours later.[10][11] On the evening of October 23, Kristy underwent an eyewall replacement cycle and weakened slightly, with its winds decreasing to 150 mph (240 km/h), by October 24.[12][13] Later that day, however, Kristy reintensified and became a Category 5 hurricane, with winds of 160 mph (260 km/h).[14] On the night of October 24, Kristy weakened back into a Category 4 hurricane,[15] then to Category 3, the following day, due to wind shear.[16][17] This weakening trend continued on October 26, with the storm's low-level center becoming exposed to the south of the diminishing mid-level circulation, resulting in the system weakening to below hurricane strength.[18]
