 The National Hurricane Center says Beryl is expected to grow into an extremely dangerous Category 4 hurricane. Barbados, St. Lucia, St. Vincent and the Grenadine Islands all under hurricane warnings. Devastating wind damage and life-threatening storm surge are forecast. The storm is then expected to move northwestward toward southern Mexico. It's unusual for such a strong storm to strike so early in the hurricane season, which forecasters say will be an especially active one.
