The Rainstorm Warning Signal is now Amber. This means that heavy rain has fallen or is expected to fall generally over Hong Kong, exceeding 30 millimetres in an hour, and is likely to continue.

There will be flooding in some low-lying and poorly drained areas. People who are likely to be affected should take necessary precautions to reduce their exposure to risk posed by the heavy rain and flooding.

Heavy rain may bring about flash floods. People should stay away from watercourses. People who are likely to be affected by flooding should take necessary precautions to avoid losses.

Members of the public are advised to pay attention to weather changes as these might lead to Red or Black warning signal situations. Those who have definite duties during rainstorms should be prepared.
