A center of circulation developed within the remnants of former Hurricane Franklin on Friday and the National Hurricane Center designated the low pressure system as Tropical Storm Jova. At 11:00 p.m. EDT on Friday the center of Tropical Storm Jova was located at latitude 19.3°N and longitude 109.8°W which put it 250 miles (400 km) south of the southern tip of Baja California. Jova was moving toward the west-northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h_ and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1003 mb.
The surface center of former Hurricane Franklin was disrupted as it passed over the mountains in Mexico. However, the middle and upper portions of the circulation crossed the mountains relatively intact. When the upper parts of the former hurricane emerged over the Eastern North Pacific Ocean, it took nearly a day for the vertical transfer of kinetic energy to spin up a new surface circulation. Eventually a new surface circulation developed and the National Hurricane Center (NHC) classified the system as Tropical Storm Jova. Established protocol is that when NHC ceases issuing an advisories on a tropical cyclone, the system is given a new name if it redevelops in a different basin.
The circulation of Tropical Storm Jova is broad, but winds to tropical storm force are occurring primarily in the northeastern quadrant of the circulation. Most of the thunderstorms are occurring in a band that wraps around the western and southern sides of the center of circulation. There are fewer thunderstorms in the eastern and northern sides of Tropical Storm Jova, There is a broad counterclockwise circulation and a distinct center, but the horizontal structure is not well organized.
Tropical Storm Jova will be moving through an environment favorable for intensification during the next 24 hours. Jova will move over water where the Sea Surface Temperature is near 30°C. An upper lever ridge over northern Mexico is producing easterly winds which are blowing toward the top of the tropical storm. Those winds are generating vertical wind shear. The shear is moderate and it will inhibit intensification. Tropical Storm is likely to intensify during the next 24 hours, but the broad circulation and vertical wind shear will limit the intensification. In a day or two Tropical Storm Jova will move over cooler Sea Surface Temperatures and it will start to weaken.
A ridge in the middle levels is steering Tropical Storm Jova toward the west-northwest. The ridge is expected to steer Tropical Storm Jova toward the west during the next several days. On its anticipated track Tropical Storm Jova will move farther west of Mexico.
