A trough of low pressure lingering around the coast of Guangdong brought several episodes of heavy rain and thunderstorms to Hong Kong this morning (May 22), causing landslides and flooding in some places. The Hong Kong Observatory issued the Black Rainstorm Warning Signal at 4.10am, the first time since July 2010.
From midnight till noon, more than 150 millimetres of rain were recorded in many places over the territory.
