Tropical Storm Emily became Hurricane Emily packing 75 m.p.h. winds in the Caribbean, and the National Hurricane Center in Miami extended a hurricane watch to the southern coast of Haiti. Emily was considered a minimal hurricane because its sustained winds had barely passed the 74 m.p.h. threshold. It didn't seem likely that the hurricane would hit the United States, said Noel Risnychok, a meteorologist at the hurricane center. Now, "the greatest concern is to the people of the Greater Antilles," he said. Earlier, Tropical Storm Emily churned past St. Vincent, causing extensive damage to agriculture and closing schools and businesses.
