Cruise ship captains sailing in the Caribbean continue to keep a close eye on Tropical Storm Erin, with winds at the 50 m.p.h. mark, as it continues to make its way across the Atlantic. At 10 a.m. (E.S.T.), the storm, considered highly disorganized at this point, was 300 miles to the east of Barbuda and moving at 18 m.p.h. However, weather forecasters are predicting the storm will miss islands in the Caribbean. Otherwise, its direction – and potential for increase -- is highly unpredictable.
