Gusts are strong as 70km/h are expected.An amber rainstorm warning was issued on Thursday morning, with more than 30 millimetres of precipitation expected to fall across the city and continue into the day.
The Hong Kong Observatory issued the alert at 9.40am and warned of heavy rain and the possibility of flooding in low-lying and poorly drained areas. Gusts as strong as 70km/h are also expected.
A thunderstorm warning was issued just an hour earlier.
“People who are likely to be affected should take necessary precautions to reduce their exposure to risks posted by heavy rain and flooding,” the Observatory said.
A band of “thundery showers” associated with a low-pressure trough is crossing the vicinity of the Pearl River estuary, bringing inclement weather.
The Observatory warned members of the public to stay away from watercourses as the rain could bring about flashfloods. Those who live in areas affected by flooding should take the necessary precautions
