Hurricane Dorian threatens the US
By Fernando Alfonso III, Mike Hayes, Meg Wagner and Rob Picheta, CNN
Dorian has wreaked havoc in the Bahamas and we're only now starting to get a sense of the extent of the destruction left in its wake.
Neko Gibson is the founder and owner of BahamasEvac services in Nassau. He spoke to CNN shortly after returning from Abacos, where he has been assisting in evacuation and rescue operations.
"Everybody's trying to do the best that they can," Gibson said Wednesday morning. "Problem is the winds and weather that has been a hazard for traffic to get in and out of Abaco."
He praised the authorities for their tireless work and said that most of the runways were still unusable with only one operating in the south.
Hurricane Dorian has left the Bahamas devastated, with residents reporting widespread damage -- homes ripped apart, water covering everything in its path. Relief organizations are scrambling to help and we're just beginning to understand how bad the damage is.

21 counties in Georgia are now under a state of emergency.
Georgia's Governor Brian P. Kemp issued an executive order Wednesday morning, expanding the state of emergency declared last week to now include Appling, Bacon, Bulloch, Clinch, Echols, Evans, Screven, Tattnall, and Ware Counties.
Counties Brantley, Bryan, Camden, Charlton, Chatham, Effingham, Glynn, Liberty, Long, McIntosh, Pierce, and Wayne counties remain under a state of emergency.
The Jacksonville Sheriff's Office posted a video showing the arrival of Dorian in the early hours of Wednesday morning.
Johnny Miller, the mayor of Fernandina Beach, Florida told CNN that the city is prepping for the worst.
"We're starting to feel a little bit of a breeze here now so we expect it to be coming in this afternoon and then going throughout this evening. We've been under mandatory evacuation for days - we look like we're going to take a big hit," Miller told CNN Wednesday.
The city, which is situated between the ocean and a river and is home to more than 12,000 residents, has created large sand barricades across vulnerable swathes of beach in preparation for the storm's arrival.
Miller said that his main concern was over getting people to evacuate before the bridges close.
He added that there's been an "unprecedented response" to the mandatory evacuation.
"We've been through several of these in the past," he added.
Rescue missions are underway in the Bahamas by civilians who are volunteering to brave treacherous conditions around the island on their own boats and jet skis in an effort to rescue neighbors, friends and strangers.
In Freeport, CNN’s Patrick Oppmann and crew were able to capture these efforts of volunteers, who are working around the clock in harrowing conditions.
The volunteers have been able to save dozens of people who are in “awful shape,” who had been seen swimming in the water, hanging onto roofs, and who had witnessed their relatives carried off by the storm surge.
Intense hurricane conditions are still battering much of the island and several boats and jet skis flipped during the rescue attempts, Oppmann reported.
However, some were hopeful that more rescues would begin Wednesday morning after a coast guard helicopter was seen flying over the island late last night.
