The No 1 typhoon signal will remain in force until 10pm on Tuesday, the Hong Kong Observatory has said, adding that Severe Tropical Storm Man-yi has weakened further.
As of 9am, Man-yi, now a tropical storm, was estimated to be about 370km south of Hong Kong and is forecast to move west at about 18km/h across the northern part of the South China Sea.
“In the past few hours, Man-yi continued to track west across the northern part of the South China Sea and weakened. Man-yi is now closest to the territory,” the forecaster said.
“Locally, rain will be more frequent at times [on Tuesday]. Under the combined effect of Man-yi and northeast monsoon, there will be occasional strong northerly winds offshore and on high ground locally [on Tuesday].”
The Observatory said minor flooding could occur in individual low-lying coastal areas with water levels near the coast higher than normal between 10pm and midnight due to the combined effect of spring tide, the northeast monsoon and Man-yi.
According to the forecaster, there will also be swells. It reminded the public to stay away from the shoreline and not engage in water sports.
