The Hong Kong Observatory issued a T1 at 6.40am on Monday as Tropical Cyclone Man-yi moved towards the SAR, and warned that it might issue a higher signal later in the day or early on Tuesday.
"The Standby Signal, No. 1 will remain in force at least until 6 p.m," said the weather forecaster in a statement.
The storm is forecast to come within 800 kilometres of the city around midnight on Monday, but is expected to weaken.
The Observatory said the approach of Man-yi and the northeast monsoon would bring windy conditions on Tuesday.
"Depending on the distance between Man-yi and the Pearl River Estuary, its degree of weakening and the change in local wind conditions, the Observatory will assess the need of issuing the Strong Wind Signal, No. 3 tonight to early tomorrow," the Observatory added.
The Observatory warned that some low-lying areas may see minor flooding in some areas because of the combined effect of the spring tide, the northeast monsoon and Man-yi, and urged the public to take care.
