 Live from NPR News in New York City, I'm Duahli Saikautau. Hurricane Beryl, the first of this season, has strengthened to a dangerous Category 4 storm, and it is getting stronger as it moves toward the southeastern Caribbean islands. NPR's Amy Held reports it is expected to make landfall on Monday. Barbados, St. Lucia, St. Vincent, and the Grenadine Islands are among the places under hurricane warnings.
