The South African city of Cape Town and surrounding areas were hit by more storms Thursday that ripped roofs off houses and caused widespread flooding, forcing at least 4,500 people out of their homes and damaging at least 15,000 structures, authorities said. The devastating weather began a week ago.

Multiple cold fronts have battered the region on the southwest tip of Africa since late last week, bringing record rainfall in some parts and gale-force winds. City authorities said the bad weather was expected to continue until the weekend and possibly into next week.
