Although Hurricane Katrina made landfall well to the west, Alabama and the Florida Panhandle were both affected by tropical-storm-force winds and a storm surge varying from {{convert|12|to(-)|16|ft|m}} around [[Mobile Bay]],<ref name=KatrinaTCR/> with higher waves on top. Sustained winds of {{convert|67|mph|km/h|abbr=on}} were recorded in [[Mobile, Alabama]], and the storm surge there was approximately {{convert|12|ft|m}}.<ref name="KatrinaTCR"/> The surge caused significant flooding several miles inland along Mobile Bay. Four tornadoes were also reported in Alabama.<ref name=KatrinaTCR/> Ships, oil rigs, boats and fishing [[pier]]s were washed ashore along Mobile Bay: the cargo ship M/V ''Caribbean Clipper'' and many fishing boats were grounded at [[Bayou La Batre]].

An [[Oil platform|oil rig]] under construction along the [[Mobile River]] broke its moorings and floated {{convert|1.5|mi|km}} northwards before striking the Cochrane Bridge just outside Mobile. No significant damage resulted to the bridge and it was soon reopened. The damage on [[Dauphin Island]] was severe, with the surge destroying many houses and cutting a new canal through the western portion of the island. An offshore oil rig also became grounded on the island. As in Mississippi, the storm surge caused significant beach erosion along the Alabama coastline.<ref name="KatrinaTCR"/> More than 600,000 people lost power in Alabama as a result of Hurricane Katrina and two people died in a traffic accident in the state. Residents in some areas, such as Selma, were without power for several days.<ref name="Power failures"/>

Northern and central [[Georgia (U.S. state)|Georgia]] were affected by heavy rains and strong winds from Hurricane Katrina as the storm moved inland, with more than {{convert|3|in|mm}} of rain falling in several areas. At least 18 tornadoes formed in Georgia on August 29, 2005, the most on record in that state for one day in August. The most serious of these tornadoes was an F2 tornado which affected [[Heard County, Georgia|Heard County]] and [[Carroll County, Georgia|Carroll County]]. This tornado caused three injuries and one fatality and damaged several houses. The other tornadoes caused significant damages to buildings and agricultural facilities. In addition to the fatality caused by the F2 tornado, there was another fatality in a traffic accident.<ref>Westbrook, Robby; WFO Peachtree City Staff.

Katrina also caused a number of power outages in many areas, with over 100,000 customers affected in [[Tennessee]], primarily in the [[Memphis, Tennessee|Memphis]] and [[Nashville, Tennessee|Nashville]] areas.
