Wanda left a total of 434 deaths, and it is estimated that an identical typhoon striking today would cause HK$2.6 billion ($335 million USD) in losses.

[1] The official track from the Japan Meteorological Agency (JMA) indicated the system first developed into a tropical cyclone on August 25,[2] whereas the Joint Typhoon Warning Center (JTWC) initiated advisories two days later, after it was observed by the Hurricane Hunters.

On August 28, reconnaissance aircraft reported winds of 75 km/h (45 mph), or tropical storm status; as such, the JTWC named the system Wanda.

[1] By that time, the typhoon was about 1600 km (1000 mi) wide, and the next day rainbands began affecting southeastern China and Hong Kong.

[3] While approaching southeastern China, Wanda reached its peak strength of 175 km/h (110 mph) in 1-minute winds, with the JTWC estimating a minimum pressure of 949 mbar.

[1] According to the JMA track, the system turned southwest into the Gulf of Tonkin, intensifying slightly before shifting southeastward and dissipating over Hainan on September 4.

The typhoon moved ashore during the daily high tide, resulting in a storm surge of at least 5 m (17 feet) above normal, especially around Tolo Harbour, which caused widespread flooding and damaged or destroyed thousands of huts and houses in Sha Tin and Tai Po.
