On August 5, an area of low pressure formed near the Marshall Islands.
The low headed northwestward while gradually organizing, strengthening into a tropical depression on the next day, with the JTWC assigning the storm the identifier 14W. Tropical Depression 14W subsequently strengthened into Tropical Storm Winnie on August 9.
Intensification became more rapid as conditions became more favorable, and Winnie reached typhoon strength on August 10.
Two days later, Winnie became the 4th Super Typhoon of the season, with peak 1-minute sustained winds of 160 mph.
Soon afterward, the eye became ragged and large, with an outer eyewall reaching 230 miles (320 km) in diameter.
On August 18, Typhoon Winnie passed north of Taiwan and made landfall in eastern China, where it winded down until it degenerated into a remnant low on August 20.
Winnie's remnant continued northeastward, bringing heavy rain and damage across China, before dissipating on August 23.
