The Hong Kong Observatory hoisted the strong wind signal, No. 3 this afternoon as severe tropical storm Nalgae looms.
The typhoon signal will remain in force at least until noon tomorrow.
This means that winds with mean speeds of 41 to 62 kilometers per hour are expected.
“At 5pm, severe tropical storm Nalgae was estimated to be about 610 kilometers south-southeast of Hong Kong and is forecast to move north-northwest at about 10 kilometers per hour toward the northern part of the South China Sea,” said the city’s meteorological agency.
“In the past few hours, Nalgae steadily edged closer to the northern part of the South China Sea. Under the combined effect of Nalgae and the northeast monsoon, strong winds are expected to prevail generally over the territory tonight and tomorrow morning, with occasional gales on high ground.”
In the past hour, the maximum sustained winds recorded at Tate’s Cairn, Waglan Island and Cheung Chau were 71, 57 and 52 kilometers per hour with maximum gusts 84, 64 and 74 kilometers per hour respectively.
The forecaster added that seas are already rough with swells.
Members of the public are advised to stay away from the shoreline and not engage in water sports. Those engaging in outdoor work or activities should also take note of the changes in weather.
The observatory said that, according to the present forecast, Nalgae will edge rather close to the vicinity of the Pearl River Estuary later on Wednesday and early Thursday.
It is expected to weaken gradually. However, its distance from the Pearl River Estuary and the degree of weakening remain rather uncertain.
The forecaster said it will closely monitor Nalgae’s movement and development while assessing whether a higher signal needs to be issued.
