STORM HISTORY
Strengthening east of the Philippines
Dinah organized east of the Philippines and moved west-northwest. It reached typhoon strength on 13 June, then continued intensifying as its track bent north. The archive records peak one-minute winds of 160 kt on 17 June, northeast of Luzon.
The storm weakened as it moved toward Taiwan after its southerly inflow was cut off. It reached the southern part of the island on 18 June and lost more strength while crossing land. Radar observations during this weakening stage showed an unusual false eye.
Taiwan damage and a northeastward turn
About 5,000 homes were destroyed in Taiwan. The reported death toll along Dinah's path was 45. Although the storm had passed its offshore peak, its crossing still caused extensive damage on the island.
After Taiwan, Dinah turned northeast toward Japan. It became extratropical near Japan on 20 June, and the archive continues tracking the system through 24 June.

When did Typhoon Dinah occur?
The archived track runs from Jun 10, 1965, 06:00 AM UTC to Jun 24, 1965, 06:00 AM UTC, with the tropical stage from Jun 10, 1965, 06:00 PM UTC to Jun 19, 1965, 09:00 AM UTC.

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.
