 Beryl strengthening into a hurricane Saturday, a day after it formed into a tropical storm in the Atlantic. The storm is churning toward the southwestern Caribbean, with forecasters warning that it's expected to strengthen into a dangerous major storm before reaching Barbados late Sunday or early Monday. Major hurricanes considered a category three or higher, with winds of at least 111 miles an hour. Beryl's already a category one, marking the furthest east that a hurricane's formed in the tropical Atlantic in June.
