We are surrounded by water with no way out,\u0022 said ABC\u0026nbsp;News correspondent Marcus Moore, who was on the ground in Marsh Harbour.\u0022Absolute devastation, there really are no words,\u0022 said Moore, surveying destroyed homes and buildings. \u0022It is pure hell here on Marsh Harbour on Aboca Island in the northern part of the Bahamas.\u0022Hurricane Dorian’s destruction in the northwestern Bahamas (Video: Alicia Nesbitt/ FB) pic.twitter.com/yyNVZaYAVa— Joel Franco (@OfficialJoelF) September 1, 2019\u0022Please someone, please come help us\u0022: Bahamas residents survey devastated apartment building after Hurricane Dorian hit Abaco Islands. https://t.co/P3RbMFtW2G pic.twitter.com/BpF3DINXCu— ABC News (@ABC) September 2, 2019Walk through storm-hit Elbow Cay shows extent of destruction in Hope Town as Hurricane Dorian lashes the Bahamas. https://t.co/cH8sAKuRWQ pic.twitter.com/WSNORsZu4o— ABC News (@ABC) September 2, 2019The Guardian characterized Dorian as \u0022the biggest storm to hit the Caribbean island chain in modern times,\u0022 with wind gusts reaching as high as 220 mph.During a press conference Sunday, Bahamian prime minister Hubert Minnis said Dorian \u0022will put us to a test that we\u0026#039;ve never confronted before.\u0022\u0022This is probably the most sad and worst day of my life to address the Bahamian people,\u0022 said Minnis. \u0022I just want to say as a physician I\u0026#039;ve been trained to withstand many things, but never anything like this.\u0022According to the National Hurricane Center, the storm remained at Category 5 strength Monday as it drifted over Grand Bahama Island, unleashing heavy rainfall and severe wind.\u0022This is a life-threatening situation. Residents on Grand Bahama Island should not leave their shelter when the eye passes over, as winds will rapidly increase on the other side of the eye,\u0022 the center said. \u0022These hazards will continue over Grand Bahama Island during most of the day, causing extreme destruction on the island.\u0022Forecasters on Monday said the storm could get \u0022dangerously close to the Florida east coast\u0022 as early as Monday night.Hurricane #Dorian continues to track south of due west during the overnight hours, leftward of the official forecast and increasing the chances of an eventual landfall in Florida. https://t.co/stvdXMwCfv— Eric Holthaus (@EricHolthaus) September 2, 2019Florida, Georgia, North Carolina, and South Carolina have declared a state of emergency as the hurricane crawls toward the U.S. coast.South Carolina Gov.
