"Tropical Storm Isaac lashed south Florida with winds and heavy rain on Sunday after battering the Caribbean, disrupting plans for the Republican National Convention in Tampa and threatening to interrupt about half of U.S. offshore oil output.Isaac is expected to strengthen to a Category 2 hurricane and hit the Gulf Coast somewhere between Florida and Louisiana at midweek - on or near the seventh anniversary of Hurricane Katrina - the U.S. National Hurricane Center said in an advisory.A hurricane watch was extended westward to include New Orleans, which was devastated when Katrina struck the city on August 29, 2005, killing more than 1,800 people and causing billions of dollars of damage to the Gulf Coast.Isaac is due to be at or near hurricane strength when its center crosses the Florida Keys late on Sunday, the Miami-based hurricane center said. A storm becomes a hurricane when sustained winds reach a minimum of 74 miles per hour.It would be the first hurricane to hit Florida in seven years and the NHC said the storm was expected to strengthen to a Category 2 hurricane, with maximum sustained winds of 105 miles per hour, as it swept up the Gulf of Mexico.At 11 a.m."^^<http://www.w3.org/2001/XMLSchema#string>
