During the evening hours of October 3, an area of showers and thunderstorms had moved off the Colombian

A tropical cyclone is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain. Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor...

 over the next 48 hours. Over the course of the next day, the area of low pressure became better defined, and the convection associated with the low became more consolidated. Thus, the National Hurricane Center upgraded their chances of the low becoming a tropical cyclone to 50%, the Medium category. Under favorable conditions, the area of disturbed weather continued to quickly become organized, and late on October 5, the NHC began issuing advisories on Tropical Depression Ten-E, located 625 mi

 affected Jova throughout the day on October 7, when the low-level circulation was mainly located just to the north of the area of deep convection. However, the wind shear decreased early on October 8, and subsequently, Jova was upgraded to a Category 1 hurricane on the Saffir-Simpson hurricane scale during the afternoon hours of October 8 as it drifted towards the east-northeast. Late on October 9, the storm was upgraded to a Category 2 hurricane with a distinct eye feature

s of 120 miles per hour (193.1 km/h). Moving towards the east, Jova reached its peak as a strong Category 3 with sustained winds of 125 mph and a pressure of 955 mbar, just below Category 4 intensity. Jova made landfall as a 100 mph Category 2 and rapidly weakened over Mexico. Shortly after landfall, Jova rapidly dissipated to a remnant low, early on October 13. Several hours later, Jova dissipated completely, as a ridge of high pressure formed directly to the storm's east.

Preparations

Early in Jova's duration, the National Hurricane Center predicted that it would strike southwestern Mexico as a hurricane in its five day forecast. Beginning on October 8, the NHC advised residents in Mexico to monitor Jova's path. The next day, the Mexican government issued a hurricane watch
