- Closest approach
- about 100km south-west
- Hong Kong Observatory
- Hurricane Signal No. 10
- Mean peak, eight stations
- 76.3km/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.
Intensified explosively close to the coast in the northern South China Sea, deepening sharply south of Hong Kong before landfall at Taishan.
