  • During the late afternoon and evening hours on April 3rd, 1974 at least 8 tornadoes, including 4 violent, long-lived storms, 
brought widespread destruction to northern Alabama. This tornado "Super Outbreak" that also affected 12 other 
eastern states caused over $50 million damage in Alabama. The F5 tornado, that nearly wiped the town of Guin off 
the map, was one of the most powerful twisters ever to strike the United States, and its path through the Bankhead 
National Forest could be seen on satellite pictures months afterwards
  • On the night of September 12th, 1979, the eye of Hurricane Frederic passed over Dauphin Island and then made landfall 
on the Alabama coast near Bayou La Batre. Peak wind gusts over 135 mph were felt along the Alabama coastline, and 
hurricane force gusts were felt as far inland as Choctaw County. Massive damage, totaling over $1 billion, was felt along 
the coast, and nearly 90 percent of the Mobile area lost electrical power due to the storm. After it made landfall, Frederic 
moved north along the Alabama/Mississippi border dropping from 3 to as much as 10 inches of rain along its path.
