Post-Tropical Storm Ian has made its second US landfall in South Carolina after causing deadly destruction in Florida.
Ian regained strength as a Category 1 hurricane near Georgetown at 14:05 local time (18:05 GMT) on Friday before losing some strength as it marched inland.
But the danger was not over. Flooding is likely to continue for several days across the region, including Florida.
Florida emergency officials announced 21 deaths as of Friday morning.
But a state medical examiner must determine whether all deaths are directly related to the storm.
Ian was one of the most powerful storms ever to hit the US when it hit Florida on Wednesday as a Category Four hurricane.
In coastal South Carolina, Ian damaged four piers and sent floodwaters into neighborhoods including the popular seaside town of Myrtle Beach.
Nearly 200,000 homes and businesses in South Carolina were without power by Friday evening.
In the city of Charleston, around 80 miles (130km) south of where the hurricane made landfall, cars were seen driving through flooded roads.
The storm is moving north with maximum sustained winds of around 50mph (85km/h), according to the National Hurricane Center (NHC).
Although Ian weakened on Friday, it is still dangerous, says the NHC.
