Tropical Depression (21-22/8/1998) An area of low pressure over the northern part of the South China Sea intensified rapidly into a tropical depression about 420 km south of Hong Kong on the night of 21 August. It tracked westwards at first but took on a more northerly course the next day. The tropical depression weakened and dissipated over water that night. In Hong Kong the Standby Signal No. 1 was hoisted at 11.55 p.m. on 21 August as the tropical depression began to pose a threat to Hong Kong. At the time, local winds were moderate to fresh easterlies and occasionally strong offshore and on high ground. Outer rainbands associated with the tropical depression also brought a few heavy squally showers and thunderstorms to Hong Kong. As the tropical depression weakened, all signals were lowered at 9.45 p.m. on 22 August. The tropical depression was closest to Hong Kong at around 8 p.m. on 22 August when it was about 350 km to the southwest. At the Hong Kong Observatory headquarters, the lowest hourly sea-level pressure of 1 006.7 hPa was recorded at 6.00 a.m. on 22 August. No significant damage was reported in Hong Kong during the passage of the tropical depression.
