STORM HISTORY
Rapid intensification after Guam
Halong developed near Chuuk in late July, initially moving little before becoming a named storm on July 29. Its developing circulation brought strong winds to Guam. The cyclone then strengthened rapidly over the western Pacific, reaching archived sustained winds of 140 knots on August 2.
An eyewall replacement cycle weakened Halong after its peak. The core later reorganized and briefly strengthened again, but the storm lost intensity as it approached Japan. It was known as Jose while in the Philippine monitoring area.
Across Shikoku and beyond Japan
Halong weakened to a tropical storm before making landfall on Shikoku on August 10. It crossed southern Japan and became extratropical on August 11. The remaining circulation continued toward Siberia, where another developing system absorbed it near the end of the archived track on August 15.

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.
