TENNESSEE VALLEY (WHNT)– Ten years ago today, Hurricane Dennis was rapidly weakening as it moved inland into southern Alabama. The storm made landfall as a Category 3 near Santa Rosa Island, Florida July 10 with max winds near 125 miles per hour. At peak strength, the storm had winds near 145 miles per hour.

Dennis was among the first named storms of what is still the most active Atlantic hurricane season on record. 28 storms were named during the 2005 hurricane season.

As activity in the Atlantic has slowly waned since, attention has shifted to the Pacific– where multiple strong hurricanes and typhoons have formed in each of the last five years.
