In the Bahamas, 'slow' government response leaves residents turning to strangers for help

Summary: Hurricane Dorian came ashore at Cape Hatteras in North Carolina Friday, still packing winds of 90 miles per hour and threatening a storm surge of four to seven feet. More than 330,000 homes and businesses across the Carolinas and southern Virginia lost power. But in the Bahamas, the situation is "dire and severe," as residents try to escape devastated areas like Abaco Island. John Yang reports.
