STORM HISTORY
Explosive deepening over the Philippine Sea
Wynne's early track crossed the Caroline Islands region before turning northwest past Guam. Its strength fluctuated during the first several days. On 8 and 9 October, the storm underwent rapid deepening from a modest typhoon into the season's strongest cyclone.
The archive records a minimum central pressure of 890 hPa and peak one-minute winds of 150 kt on 9 October. Wynne continued west-northwest after its peak, then turned north east of Taiwan as its winds gradually declined.
A northeastward passage near Japan
Wynne curved northeast through the waters south of Japan and accelerated eastward. No archived center position lies over land, although the season account reports power outages in Japan and ten deaths associated with the storm.
The tropical stage ended late on 14 October. The archive continues into 15 October as the circulation moved away from Japan over the Pacific.

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.
