STORM HISTORY
Repeated revival south of Hawaii
Genevieve became a tropical storm well east-southeast of Hawaii on July 25. Wind shear soon weakened it, and the circulation repeatedly alternated between a depression and a remnant low. Dry air also limited development as the system continued westward south of Hawaii.
Conditions improved in early August. Genevieve regained tropical-storm strength on August 5 and became a hurricane the following day. Rapid intensification continued as it approached and crossed the International Date Line on August 7, after which it was classified as a typhoon.
The strongest phase in the western Pacific
Archived sustained winds reached 140 knots on August 7. Genevieve then weakened as stronger wind shear, cooler water and sinking air disrupted its thunderstorms. It turned northeastward late in its life and lost its tropical structure on August 14. The storm remained offshore throughout, with no reported damage or deaths.

METHODOLOGY
Data sources and limitations
The map and summary are generated from NOAA's IBTrACS v04r01 archive. Wind and category use US-agency records; minimum pressure is calculated during the tropical stage, with the archive's pressure source retained. Category 5 refers to the Saffir–Simpson one-minute wind scale; local agencies may use different classifications. Coastlines use Natural Earth's 1:10m land data.
Track distance adds great-circle distances between consecutive observations, excluding gaps over 12 hours. This track has no gaps over 12 hours. The line shows the storm's center, not its size, rainfall or flood extent. Converted wind speeds are rounded to the nearest whole unit.
