Readers' pictures: Dark storm clouds gather over Hong Kong

It could be a scene from a Hollywood movie: thick black clouds roll across Hong Kong's historic Victoria Harbour ahead of a superstorm.

But this was the real thing on Tuesday afternoon as the city prepared for an amber rainstorm.

The image below, tweeted by Reuters financial news reporter and presenter Cathy Yang, was taken at 3pm from the 42nd floor of Gloucester Tower in Hong Kong, and shows dark clouds rolling into the harbour.
