The Hong Kong Observatory lowered the typhoon signal to No 1 on Wednesday morning, as the tropical depression moves away from the city.
The No 3 typhoon signal was raised on Tuesday afternoon. At 4pm, the tropical depression over the northern area of the South China Sea was estimated to be about 120 kilometres south-southwest of Hong Kong and forecast to move east slowly, across the coastal waters of neighbouring Guangdong province.
“The tropical depression will be closest to Hong Kong overnight tonight, skirting about 100km south of the territory,” the Observatory said on Tuesday.
Do online lessons mean the end of typhoon days?
“With the approach of the tropical depression, the winds ... are expected to strengthen tonight.”
Earlier in the day, the Observatory had suggested the slowly moving storm was unlikely to generate strong winds, adding showers and squalls were expected throughout Tuesday and over the next few days.
The standby signal was first issued on Monday at 9.40pm.
By midnight, the tropical depression over the northern part of the South China Sea was estimated to be about 260km southwest of Hong Kong, and was forecast to move east at about 12km/h across the coastal waters of Guangdong province.
