Part of the 2014 Pacific hurricane and typhoon seasons | |
Hurricane Genevieve, also referred to as Typhoon Genevieve, was the first tropical cyclone to track across all three northern Pacific basins since Hurricane Dora in 1999. Genevieve developed from a tropical wave into the eighth tropical storm of the 2014 Pacific hurricane season well east-southeast of Hawaii on July 25. However, increased vertical wind shear caused it to weaken into a tropical depression by the following day and degenerate into a remnant low on July 28. Late on July 29, the system regenerated into a tropical depression, but it weakened into a remnant low again on July 31, owing to vertical wind shear and dry air.
The remnants redeveloped into a tropical depression and briefly became a tropical storm south of Hawaii on August 2, yet it weakened back into a tropical depression soon afterwards. Late on August 5, Genevieve re-intensified into a tropical storm, and intensified into a Category 1 hurricane on the next day when undergoing rapid deepening because of favorable conditions. Early on August 7, Genevieve strengthened into a Category 4 hurricane, shortly before it crossed the International Date Line and was reclassified as a typhoon, also becoming the thirteenth named storm of the 2014 Pacific typhoon season. Late on the same day, Genevieve reached peak intensity while it was located west-southwest of Wake Island.
Typhoon Genevieve started to gradually weaken at noon on August 8, and stronger vertical wind shear provided by a TUTT cell began to weaken the system further on August 9. The typhoon crossed 30° north at noon on August 10 and weakened to a severe tropical storm soon afterwards, because of unfavorable sea surface temperature and expanding subsidence. Genevieve weakened into a tropical storm on August 11 and a tropical depression the following day, as its deep convection diminished. On August 13, the system turned northeastward, before degenerating into a post-tropical cyclone on August 14, with the JMA reporting the system to have dissipated. However, the Ocean Prediction Center (OPC) tracked Genevieve's remnants for another day, which crossed over the International Date Line again, until they were absorbed by another extratropical cyclone on August 15.
