It’s the region’s worst in half a century. A dozen people have been killed and hundreds injured after a typhoon swept across the southern China region Wednesday. At least eight were killed in the gambling enclave of Macau, as winds of up to 109 mph battered the region. Meanwhile an estimated 27,000 people were evacuated to Chinese emergency shelters before the storm made landfall. With widespread blackouts, flooding and business closures in Hong Kong, which issued its highest storm warning, it’s expected that Hato will cost up to $1 billion there.
