Tropical Storm Fay was expected to move across Haiti on Saturday, the National Hurricane Center said. Tropical Storm Fay formed over the island of Hispaniola on Friday and is moving toward Cuba, CNN reported. The storm, the sixth of the Atlantic 2008 season, had maximum sustained winds near 45 mph with higher gusts, forecasters said. The storm formed Friday over the Dominican Republic in the Caribbean Sea. As of 2 a.m. ET Saturday, the center of Fay was about 60 miles east of Port Au Prince, Haiti, and about 260 miles east-southeast of Guantanamo, Cuba. It was moving west at about 14 mph and was expected to continue moving west-northwest over the next day, forecasters said. Fay is expected to dump 4 to 8 inches of rain over Hispaniola and eastern Cuba, with possible isolated amounts up to 12 inches, the hurricane center said. Heavy rain could trigger floods and mudslides and raise tides 1 to 2 feet above normal levels in the warning area. A tropical storm warning is now in effect for the entire coast of Haiti, the hurricane center said.
