Heavy rains from Hurricane Dorian are battering the coasts of South and North Carolina after causing destruction and at least 20 deaths in the Bahamas.
The category two storm is moving slowly north along the eastern US seaboard. Thousands of homes are without power.
Forecasters warn that some areas could see dangerous storm surges.
But two high tides have come and gone in Charleston, South Carolina, and Dorian is expected to weaken slowly over the next few days.
It currently has maximum sustained winds of 105mph (165km/h), down from 115mph earlier in the day.
On 1 September it hit the Bahamas with winds of up to 185mph – equalling the highest ever recorded at landfall. It battered the Abaco Islands and Grand Bahama, in the north of the archipelago, for two days.
Bahamas PM Hubert Minnis called the storm “one of the greatest national crises in our country’s history”. He expected the number of fatalities to increase.
