STORM HISTORY
North through the western Pacific
The archive begins Judy's track near 8°N, 154.3°E on 27 September. It moved northwest and then north, passing through the longitude of the Marianas before approaching the Bonin Islands region. Its one-minute winds peaked at 150 kt at 06:00 UTC on 2 October.
Northeast away from Japan
Judy turned northeast after its peak, moving east of Japan as its winds declined. The minimum archived pressure of 920 hPa occurred six hours after the first peak-wind observation. By the end of its tropical phase on 4 October, Judy had moved into the open Pacific east of Honshu.
Later positions continue northeast toward the Aleutian region and the date line. The final archived point falls on 10 October, several days after the end of the tropical-stage observations.

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.
