The sound of rush hour in Zhuhai on China's southern coast has been replaced by howling winds and sheets of rain.

Branches from falling trees and what looked like pieces of metal from the edge of a building flew along empty roads on Wednesday as typhoon Ragasa bore down.

Police vehicles have been patrolling the streets with megaphones, urging people to stay inside - but it is difficult to hear them above gusts of 100mph (160km/h) winds. Still, the thundering skies and a drenched Zhuhai are enough of a warning – apart from an occasional cyclist, determined to get to work, most people heeded the advice, bringing this city of almost three million people to a standstill.

The strongest storm the world has seen this year, Ragasa has been making its way across the South China Sea after battering the Philippines and Taiwan. At least 15 people have died in eastern Taiwan after a mountain lake burst its banks, officials have said.

As the storm brushed past Hong Kong, steep waves crashed into land, inundating coastal areas, alongside powerful winds and rain, leaving more than 60 people injured.
