The amber rainstorm signal, issued by the Observatory at 11.45am, has been taken down since 1.20pm, but wet weather is expected to continue throughout the day and into the night. Observatory scientific officer Stephen Lau Po-wing said the intensive rain was mainly due to a shower zone moving towards Hong Kong from the river mouth of the Pearl River Delta. “The trough of low pressure also brings thunderstorms,” he said. According to Lau, more than 50mm of rain was recorded over the eastern part of Hong Kong Island and the Tai Po area in the New Territories this morning. Occasional rain and squally thunderstorms are still expected for this afternoon (Friday) and tonight. There may be flooding in some low-lying and poorly drained areas. People who are likely to be affected should take necessary precautions. Heavy rain may also bring about flash floods. The public is advised to stay away from watercourses. “The weather this weekend will be better than in the past week, and there will be chances to see the sun,” Lau said. More updates will follow.
