As of Sunday night, Tropical Storm Ernesto's winds have slowed to near 50 miles-an-hour. That's down from 75 miles an hour earlier Sunday when it became the first hurricane of the Atlantic season. Forecasters at the National Hurricane Center think Ernesto will become a hurricane again before hitting Cuba's southeastern coast Monday and menacing Florida later in the week. The storm lashed the southern coast of Haiti and the Dominican Republic Sunday with heavy rain, flooding homes. In Florida, a hurricane watch has been issued for the entire Florida Keys and visitors have been ordered to leave. Governor Jeb Bush has issued a state of emergency. NASA is keeping close tabs on Ernesto. They plan a decision in the morning on whether to roll space shuttle Atlantis back inside or go head with its planned launch Tuesday.
