Tropical Depression Five was an Atlantic tropical cyclone that lasted for 12 hours , although its remnants persisted for almost another week . Its precursor was from a non-tropical trough east of Florida , and on August 10 it developed in the southeastern Gulf of Mexico . It was the fifth depression of the 2010 Atlantic hurricane season . The system was declassified as a tropical cyclone the following day , a remnant circulation later moved over Louisiana and Mississippi , producing heavy rainfall and causing flooding . Along the Florida coast , the system produced heavy waves that contributed to two deaths . Moving inland , the remnants of the depression reached central Alabama before turning southward . The system nearly redeveloped into a tropical cyclone on August 16 after it again reached the Gulf of Mexico , but it became disorganized and turned northward into Mississippi . The depression twice caused BP to delay work in building a relief well to combat the Deepwater Horizon oil spill
