1958 Western Pacific typhoon season

Typhoon Winnie 1958

Typhoon Winnie intensified just before reaching eastern Taiwan in July 1958. The island's mountains weakened the cyclone before it crossed the Taiwan Strait and reached southeastern China. Its short, intense passage caused casualties and injuries in Taiwan.

STORM HISTORY

Rapid strengthening east of Taiwan

Winnie developed east of Luzon and moved northwest. After an initial burst of strengthening and a brief weakening, it intensified again on its approach to Taiwan. The archive records one-minute sustained winds of 150 kt at 00:00 UTC on 15 July, its Category 5 peak.

Across Taiwan to China

Winnie struck eastern Taiwan on 15 July and weakened over the mountainous terrain. The strongest sampled center-over-land observation carries 120 kt that afternoon. The historical account reports 31 casualties and 53 injuries during the Taiwan crossing.

After crossing the Taiwan Strait, Winnie reached southeastern China and weakened inland. Its tropical-stage archive ends on 16 July, while later positions continue until 18 July.

QUICK ANSWERS

Winnie in brief

What was Typhoon Winnie's highest wind speed?

173 mph, the highest one-minute sustained wind in its tropical stage, recorded on Jul 15, 1958, 12:00 AM UTC.

What category was Typhoon Winnie?

Category 5 at its peak on the Saffir–Simpson one-minute wind scale, first reaching Category 5 on Jul 15, 1958, 12:00 AM UTC. Other agencies classify storms differently.

What was Typhoon Winnie's lowest pressure?

925 mb, the minimum central pressure recorded during its tropical stage, on Jul 13, 1958, 12:00 AM UTC.

When did Typhoon Winnie occur?

The archived track runs from Jul 11, 1958, 12:00 AM UTC to Jul 18, 1958, 12:00 AM UTC, with the tropical stage from Jul 11, 1958, 12:00 AM UTC to Jul 16, 1958, 09:00 AM UTC.

Where did Typhoon Winnie form?

In the Western Pacific basin, in the 1958 season. Its first archived position is 16°N, 135°E on Jul 11, 1958, 12:00 AM UTC.

Did Typhoon Winnie make landfall?

The archive places its center over land at 2 recorded positions; the strongest is 138 mph on Jul 15, 1958, 03:00 PM UTC. Positions are six-hourly, so this is not a landfall chronology.

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.
