STORM HISTORY
From the Caroline Islands toward Japan
Rosie developed near the Caroline Islands in mid-July. Forecasters classified it as a tropical depression on July 18, and it strengthened into a super typhoon over the following days. Peak one-minute winds reached 140 kt on July 22, with a minimum central pressure of 920 hPa recorded early the next day.
A weaker landfall on Shikoku
The typhoon moved north and weakened before reaching Shikoku on July 26 at Category 1 strength. Its archived overland wind estimates are far below the offshore peak, separating the storm's strongest phase from the conditions at landfall.
Japan recorded five deaths and about 1,200 displaced people. The saved season account places damage at ¥11.1 billion in 1997 currency. PAGASA also tracked the storm under the Philippine name Elang during its July 22–26 passage.

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.
