Hurricane Dorian is expected to bring "life-threatening storm surges" up the US east coast after causing destruction and at least 20 deaths in the Bahamas.

 The category three storms are currently lashing the coast of the Carolinas as it moves slowly north. Tens of thousands of people are without power.

Residents from Georgia up to Virginia are being warned to listen to emergency advice. Dorian weakened after hitting the Bahamas but has now strengthened again. It currently has maximum sustained winds of 115mph (185km/h).

The US National Hurricane Center (NHC) said that at 09:00 GMT Dorian was 130km (80 miles) south-east of Charleston and moving north at about 13km/h (8mph). It is expected to turn north-east later on Thursday and speed up. South Carolina has prepared for a record storm surge and the effects are already being felt. More than 100,000 people were without power in coastal areas on Thursday morning, energy officials said.
