The Hong Kong Observatory said it will consider issuing the Strong Wind Signal No 3 during the daytime on Saturday, with Tropical Cyclone Wipha set to strengthen in intensity gradually.
The Standby Signal No 1 will be issued around midnight on Friday as the storm is expected to come within 800 kilometres of the city then, the forecaster said.
"Wipha will be rather close to the vicinity of the Pearl River Estuary on Sunday and expected to skirt around 50 kilometres from Hong Kong," it said.
The weather watchdog said the weather will remain hot on Saturday, with strong winds to hit later in the day.
It also urged the public to stay away from the shoreline, as thunderstorms and heavy rain will pour over the SAR on Sunday.
The observatory will also consider issuing higher typhoon signals if needed.
