The Hong Kong Observatory said it will consider issuing the Gale or Storm signal No 8 in the wee hours of Sunday.
Severe tropical storm Wipha is forecast to move across the northeastern part of the South China sea and edge closer to the coast of Guangdong.
At a press briefing on Saturday, acting senior scientific officer Shum Chi-tai said strong winds will start picking up later on Saturday.
"According to the present forecast, Wipha will continue to intensify and move towards the vicinity of the Pearl River Estuary today, with its outer rain bands and associated strong winds affecting the coastal areas of Guangdong gradually," he said.
"Local winds will strengthen later today."
There will also be more showers gradually with squally thunderstorms, according to the observatory.
Flooding may occur in low-lying coastal areas tomorrow morning due to the influence of storm surges.
Shum was speaking as Secretary for Home Affairs Alice Mak said her bureau had already started preparatory and prevention works ahead of the typhoon to minimise the impact of Wipha on the public.
Speaking on Saturday, she said the 18 district offices, district councillors, village representatives and care team members had started on the work, particularly in outlying and low-lying areas.
"Village representatives have contacted villagers in outlying areas and helped them prepare ahead of the storm," Mak said.
"In some of the areas that are more easily flooded, sandbags have been put in place to prevent flooding," Mak said.
"As for low-lying areas, we have closed flood gates at locations where the Drainage Services Departments have installed them," she added.
Mak also said community centres and halls will be open when the No 8 is in force for use as temporary shelters.
Staff will also be deployed to assist people in need, she said.

2025 black rainstorm may be among Hong Kong's costliest natural disasters for insurance
This week's record-breaking deluge may rank among Hong Kong's costliest natural disasters for insurers, as the owners of cars and properties started to submit claims for damages caused by 11 hours of the highest category of rainstorm. Advertisement The payouts may top the damages caused by last month's Typhoon Wipha , but will be less than the HK$1.54 billion (US$196.2 million) havoc wrought by the last black rainstorm in September 2023, thanks to the mitigating measures taken by the government and business owners, said Zurich Insurance's Greater China CEO, Eric Hui. 'We received many claims from car owners due to flooding,' Hui said. 'There are also claims from homeowners who suffered losses from the heavy rain.' Hong Kong received 358.8mm (14 inches) of rainfall on Tuesday, the heaviest precipitation in August since the Hong Kong Observatory began keeping records in 1884. The most severe category of rainstorm warning was in place for 11 hours, second only to the one issued on September 7, 2023, which lasted for 16 hours and 35 minutes.

Multi-departmental effort over Sha Tin reservoir alert
Multi-departmental effort over Sha Tin reservoir alert The Home Affairs Department activates its emergency notification system after the water level at the Lower Shing Mun Reservoir reaches the warning threshold. Photo: RTHK Calvin Tang speaks to Hailey Yip A Sha Tin district council member said a multi-departmental emergency plan was activated on Tuesday after the Lower Shing Mun Reservoir's water level reached a critical threshold. The Home Affairs Department issued a public warning urging residents to avoid both sides of the Shing Mun River. The department said it had notified residents in nearby housing estates, such as Mei Lam Estate, May Shing Court, Mei Chung Court and Granville Garden. It said it had also alerted the Sha Tin District Office, Drainage Services Department and the police based on an emergency mechanism. "The Home Affairs Department has actually activated its emergency notification system. We have informed all potentially affected housing estates and villages through established channels, like care teams and property management offices," Sha Tin district councillor Calvin Tang told RTHK. "We secured the area... the police on-site to cordon all and close all public access to the riverbanks, including the pedestrian walkways and cycling tracks to prevent accidents. "The Drainage Services Department has deployed its emergency response teams to patrol the entire district, especially known flooding blackspots to clear all blockages and carry out urgent repairs to ensure storm water can be discharged effectively. "The (Water Supplies Department) began diverting some of the water flow from lower Shing Mun River to other reservoirs to relieve pressure and slow down the rate at which the water level is rising." Tang said that large-scale evacuation was unnecessary, noting similar threshold levels have occurred during past extreme weather events like Typhoon Mangkhut in 2018. He added that the government has a comprehensive multi-project strategy to bolster Sha Tin's long-term flood resilience. "Like in the mainstream flood storage, there is a major project that is already under way to construct such a storage tank in Sha Tin Park. The tank will have a capacity of around 8,600 cubic metres and will temporarily store excess rainwater during storms. It will be available in 2029," he said. "The (Drainage Services Department) has some downstream improvements. It includes some regular clearing of the river channel to maintain its depth and the capacity to ensure the draining outlets are clear. "There is a plan of 1.8 kilometres new flood walls being constructed among the Shing Mun River to provide extra physical barrier against the high water levels."
