STORM HISTORY
North through the western Pacific
Olive's archived track begins near the Mariana Islands on 26 August. It initially moved northeast, then settled onto a northward course. The storm strengthened quickly, reaching peak one-minute winds of 150 kt on 29 August while still far south of Japan's latitude.
After its peak, Olive continued north along roughly the same longitude for several days. Its winds declined as it reached the waters east of Honshu, and the track began bending northeast. No archived center position lies over land.
Into the northern Pacific
Olive's tropical stage ended on 3 September, after the circulation had moved well east of Japan. The later track continues northeast across the open Pacific, ending near the latitude of the Kuril Islands on 6 September. Its strongest phase had taken place much farther south over open water.

No archived position places Typhoon Olive's center over land, but positions are six-hourly and a brief landfall can fall between them.
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.
