Effects of Hurricane Isaac in Florida were severe local flooding in South Florida and tornadoes in the central and northern portions of the state in August 2012 . Hurricane Isaac formed from a tropical wave while located east of the Lesser Antilles on August 21 , 2012 . The storm moved westward , crossed through the Leeward Islands , and entered the Caribbean Sea on August 22 . Isaac initially struggled to intensify and defied predictions of it strengthening into a hurricane . The storm made its first landfall in Haiti as a midgrade tropical storm prior to making a second one in Cuba later that day . It remained somewhat disorganized while moving through the Straits of Florida and passed near the Florida Keys on August 27 . The storm threatened to strike the Tampa Bay Area during the 2012 Republican National Convention and move ashore in the Florida Panhandle as a major hurricane . However , it continued northwestward and avoided landfall in the state . The storm finally became a hurricane late on August 28 . Isaac made two landfalls in Louisiana on August 29 , the first near the mouth of the Mississippi River and the other near Port Fourchon . The storm steadily weakened and eventually dissipated over Missouri on September 1
