Hurricane Dorian on path to Florida, 'extreme damage' on Bahamas

Hurricane Dorian has left parts of tourism-dependent Bahamas in ruins and relief officials on Tuesday were preparing for an unfolding humanitarian crisis with the scale of the catastrophe only beginning to emerge.

Aerial video recorded over the Bahamas' Great Abaco Island showed mile upon mile of flooded neighbourhoods, pulverized buildings, upturned boats and shipping containers scattered like Lego toys. Many buildings that had not been flattened had walls or roofs partly ripped away.

While its winds had diminished to a Category 2 storm on the five-step Saffir-Simpson scale of intensity, Dorian expanded in size and picked up speed on Tuesday. Forecasters said it would come "dangerously close" in the next 36 hours to Florida's east coast, where more than a million people have been ordered evacuated.

Bahamas Prime Minister Hubert Minnis on Tuesday put the death toll at seven.

"We can expect more deaths to be recorded. This is just preliminary information," Minnis told a news conference.

"Marsh Harbor has suffered, I would estimate, in excess of 60 percent damage to their homes," Minnis said, referring to the port on Great Abaco. "The Mud, as we know, has been completely destroyed or decimated," he said in reference to a shantytown known as The Mud and The Peas.

One Twitter post with the handle @mvp242 described how "victims are being loaded on flatbed trucks across Abaco," showing a rain-blurred photo of limp bodies strewn across a truck bed. Other messages on Twitter described whole communities being swept away.

Minnis said he saw people waving for help in a community near Coopers Town on Great Abaco, after it had been cut off by flooding.

"There were around 30 people trapped and waving yellow flags, sheets and shirts to bring our attention to their survival," said Minnis.

A video posted on Twitter showed a storm surge rising up inside a two-story home, the sofa and other furniture floating toward the second floor. Another showed residents trying to swim from one home to another through the surge.

In another, a woman repeatedly says: "Please, pray for us," after the storm ripped the roof off her apartment building and she sheltered on top with her 4-month-old baby and other residents. "Some people the water just sucked them," she said. Some people didn't make it."

Reports from Grand Bahama island and its main town of Freeport have been more sketchy. Relief agencies have been unable to get through because of weather conditions, Minnis said.

The Miami-based US National Hurricane Center said storm surges in Grand Bahama were 12 feet to 18 feet (3.7-5.5 m) above normal tide levels.

Long Lists Of Missing

With telephones - including emergency lines - down on Abaco and Grand Bahama islands, residents posted lists of missing loved ones across social media platforms.

A single Facebook post inviting the names of missing people by local media outlet Our News Bahamas had 1,600 comments listing lost family members since it went live late on Tuesday morning.

The NHS said in an 8 p.m. EDT (0000 GMT) advisory that Dorian packed sustained winds of 110 miles per hour (175 kph) and was moving northwest at 6 mph (9 kph), as it churned about 105 miles (170 km) east of Cape Canaveral, Florida.

Hurricane-force winds had expanded to 60 miles (96 km) from the storm's core. "Dorian is expected to remain a powerful hurricane during the next couple of days," the NHS said.

The exact toll of the devastation in the Bahamas will not be clear until the storm completely passes and rescue crews can get on the ground, said Theo Neilly, the Bahamian consul general in Washington. Dorian has battered the Bahamas for the past three days. "We expect it to be very devastating and the damage to be extreme," Neilly said.

As many as 13,000 homes in the Bahamas may have been destroyed or severely damaged, the International Federation of Red Cross and Red Crescent Societies said, in the strongest storm ever to hit the Bahamas.

Food may be required for 14,500 people in the Abaco Islands in the northern Bahamas and for 45,700 people in Grand Bahama, the U.N. World Food Programme said in a statement. The preliminary estimates were based on an assessment by representatives from Caribbean countries, the WFP and other organizations.

The US Agency for International Development said on Twitter it was "airlifting critical relief items - like plastic sheeting, hygiene kits, and water containers" from Miami to theBahamas. The U.S. Coast Guard said four of its helicopters were assisting in the humanitarian effort.

Dorian, which killed one person in Puerto Rico before bashing into the Bahamas on Sunday, is tied for the second-strongest Atlantic storm to make landfall with Gilbert (1988), Wilma (2005) and the 1935 Labor Day hurricane.

It was expected to hit Florida with hurricane conditions overnight, before bringing its powerful winds and dangerous surf along the coasts of Georgia, South Carolina and North Carolina by late on Thursday.

The governors of those states have ordered evacuations of coastal counties.
