- Peak wind
- 111km/h
- Lowest pressure
- 975hPa
- Closest approach
- about 50km south-east
- Hong Kong Observatory
- Hurricane Signal No. 10
- Mean peak, eight stations
- 75.6km/h
- Waglan Island
- not recorded
Ten-minute mean sustained winds measured by the Observatory, not computed here. Stations differ greatly: Waglan Island faces open sea while urban stations sit among buildings, so the same storm can read twice as high at one as at the other.
A broad circulation that passed roughly 50 km south of Hong Kong. The No. 10 signal stayed up for close to seven hours.
