As Hurricane Dorian slogs up the Carolina coast, forecasters are predicting high storm surges and drenching rains that could trigger flooding and unleash environmental hazards in areas still recovering from last year’s Hurricane Florence. The National Weather Service issued a hurricane warning Wednesday for the Atlantic coast from northern Georgia to southern Virginia, predicting a “potentially life threatening storm surge” up to 8 feet (2.4 meters) around the North Carolina-South Carolina line.
