Part of the 2014 Pacific hurricane and typhoon seasons

Hurricane Genevieve, also referred to as Typhoon Genevieve, was the fourth-most intense tropical cyclone of the North Pacific Ocean in 2014. A long-lasting system, Genevieve was the first one 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.
