The amber rainstorm warning signal and the thunderstorm warning remain in effect as of 11am on Wednesday as torrential rain causes flooding and chaos on the roads.
The amber signal indicates heavy rain exceeding 30mm in an hour. Rainfall is likely to continue with gusts reaching 80km or more per hour, according to the Observatory.
Roads were flooded and residents were unprepared as the wet weather took them by surprise. Some buildings saw leaks spring from the ceiling as Sheung Shui’s MTR station saw water raining from light fixtures.
The amber signal was issued at 6:30am.
As of 10:30 am, rainfall was most severe in the southern New Territories as well as most of Hong Kong Island.
These areas received the most precipitation with around 10-20mm of rain over the last hour.
Temperatures may reach as high as 25 degrees Celsius on Wednesday.
The Observatory expects rain and showers throughout the week until next Wednesday while temperatures remain stable.
