 In the Caribbean, hurricane warnings are in effect for thousands of people in Barbados, Grenada, Tobago and St. Vincent after a powerful Category 4 storm made landfall on one of the islands of Grenada. Hurricane Burrell blew rooftops off of homes today with maximum sustained winds of 150 miles per hour, just short of a Category 5. Authorities say the dangerous storm is one of the strongest to form this early in the Atlantic.
