The storm parked over the Bahamas and pounded it for over a day and a half with winds up to 295km/h and torrential rains, swamping neighbourhoods in muddy brown floodwaters and destroying or severely damaging thousands of homes. The US Coast Guard, Britain's Royal Navy and relief organisations including the United Nations and the Red Cross joined the burgeoning effort to rush food and medicine to survivors and lift the most desperate people to safety by helicopter. The US government also dispatched urban search-and-rescue teams. Damage is seen from Hurricane Dorian on Abaco Island.

"Today will tell the magnitude of the problem," Health Minister Duane Sands said.

Londa Sawyer stepped off a helicopter in Nassau, the capital, with her two children and two dogs after being rescued from Marsh Harbor in the Abaco islands. Loading "It looks like a bomb hit," she said. "I'm just thankful I'm alive. The Lord saved me." Sawyer said that her home was completely flooded and that she and her family fled to a friend's home, where the water came up to the second floor and carried them up to within a metre of the roof. She said she and her children and the dogs were floating on a mattress for about half an hour until the water began receding. Sandra Cooke, who lives in Nassau, said her sister-in-law was trapped under her roof for 17 hours in the Abaco islands and wrapped herself in a shower curtain as she waited.

"The dog laid on top of her to keep her warm until the neighbours could come to help," she said. "All of my family lives in Marsh Harbour, and everybody lost everything. Not one of them have a home to live in anymore." Abaco and Grand Bahama islands, with a combined population of about 70,000, are known for their marinas, golf courses and all-inclusive resorts. Nearly half the homes were feared severely damaged or destroyed, the Red Cross said on Tuesday.

Hurricane-force winds extended up to 110 kilometres from its centre. Dorian was expected to pass dangerously close to Georgia and perhaps strike South Carolina or North Carolina on Thursday and Friday with the potential for over 30 centimetres of rain in some spots. Forecasters warned that Dorian is likely to cause storm surge and flooding even if its core does not blow ashore.

"Hurricane Dorian has its sights set on North Carolina," Governor Roy Cooper said. "We will be ready." With the threat to Florida easing and the danger shifting northward, Orlando's airport reopened, along with Walt Disney World and Universal. To the north, ships at the big Norfolk, Virginia, naval base were ordered to head out to sea for safety, and warplanes at Langley Air Force Base in Virginia were sent inland. The US mainland recorded its first death in connection with the hurricane, that of an 85-year-old man in North Carolina who fell off a ladder while trying to prepare his home for the storm. Dorian was also blamed for one death in Puerto Rico. On Tybee Island, Georgia, Debbie and Tony Pagan stacked their beds and couches atop other furniture and covered their doors with plastic wrap and sandbags before evacuating the place. Their home flooded during both Hurricane Matthew in 2016 and Irma in 2017. "It's a terrible way to live," Debbie Pagan said. "We have the whole month of September and October to go. How would you like to be living on pins and needles?"

Another Tybee islander, Sandy Cason, said: "The uncertainty and the unknown are the worst part. Just not knowing what's going to be here when you get back." Loading Along King Street in historic Charleston, South Carolina, dozens of shops and restaurants typically bustling with tourists were boarded up, plywood and corrugated metal over windows and doors, as the flood-prone downtown area braced for high water. Mark Russell, an Army veteran who has lived in South Carolina much of his life, went to a hurricane shelter right away. As for those who hesitated to do so, he said: "If they go through it one time, maybe they'll understand." AP
