Genevieve (2008)

A tropical wave that crossed Africa on 6 July moved into the eastern North Pacific and developed into Tropical Depression Eight-E on 21 July 2008 about 220 nautical miles south-southwest of Acapulco, Mexico. The system became Tropical Storm Genevieve later that day and moved generally west-northwestward. After crossing a region of cooler water left by Hurricane Fausto it briefly weakened, then re-intensified and strengthened rapidly on 24–25 July. Genevieve was a tropical cyclone from 21 July until it degenerated to a remnant low on 27 July; that remnant circulation persisted until about 31 July and finally dissipated by 2 August well east-southeast of Hilo, Hawaii.

Genevieve remained over open ocean for its entire life and did not make any landfalls. No watches or warnings were required for any coastal areas.

The storm’s maximum sustained winds reached 65 knots (75 mph) and its lowest central pressure was 987 mb, making it a Category 1 hurricane at peak intensity around 1200 UTC 25 July 2008, when it was located roughly 510 nautical miles southwest of Cabo San Lucas. Its hurricane intensity lasted only about a day before steady wind shear and cooler sea surface temperatures caused weakening.

Because Genevieve stayed far offshore, there were no reports of storm surge or coastal inundation tied to the cyclone. The report also lists no land-based rainfall totals linked to Genevieve; its impacts were confined to the open ocean.

There were no reports of damage or casualties—no deaths or injuries were attributed to Genevieve. Noteworthy in the analysis was that Genevieve passed over an unusually cool patch of ocean left by Hurricane Fausto (sea surface temperatures reduced by about 3°C), which temporarily suppressed its strengthening and affected intensity forecasts. Overall, official track forecasts were better than the model guidance for longer lead times, and official intensity forecasts compared favorably with long-term averages for the eastern North Pacific.
