Matthew's winds waning but flooding to continue
The US National Hurricane Center says that Matthew's winds are diminishing along the North Carolina coast, but that water levels will remain elevated.
The centre said in its 5 p.m. ET Sunday update that the centre of the storm was about 200 miles (320 kilometres) east-southeast of Cape Hatteras, North Carolina, and had maximum sustained winds of near 75 mph (120 kpm).
The centre, in what will be its last update on the remnants of Matthew, says life-threatening flooding will continue over portions of eastern North Carolina that have received record rains from Matthew.
President Barack Obama says his team is working to make sure that states are getting the resources they need from the federal government after the hurricane pounded the Southeast.
Speaking at a political fundraiser in Chicago, Obama said that he has been in touch with the governors of Florida, North Carolina, South Carolina and Georgia. He tells people in those states that the government wants to make sure they know "we've got your back".
Matthew has killed at least 17 people in the US, nearly half of them in North Carolina. The Tar Heel state was inundated by torrential rains from the storm.
