Obama declares state of emergency in 3 states

US President Barack Obama declared a state of emergency in the US state of Georgia on Thursday, adding it to the states of Florida and South Carolina as being eligible for federal hurricane relief.

He ordered federal aid to supplement state and local efforts and authorised the Homeland Security Department and the Federal Emergency Management Agency to coordinate disaster relief as Hurricane Matthew bore down on the US coast.

"Hurricane Matthew is as serious as it gets. Listen to local officials, prepare, take care of each other," Mr Obama advised residents in the path of the storm in a post on Twitter.

Hundreds of flights were cancelled in south Florida, and cancellations were expected to spread north along the storm's path in the coming days, said airlines such as American Airlines, Delta Airlines and United Airlines.
