Hurricane Dennis made landfall on Sunday, July 10, at 2:24pm CDT, as a Category 3 hurricane on the Saffir-Simpson scale with sustained winds of 120 mph. The storm made landfall near Pensacola Beach, Florida, before proceeding inland across southern and western Alabama, then into northeast Mississippi.

Dennis began weakening almost immediately after landfall, and weakened at an unusually fast pace before reaching the Tennessee Valley. This rapid collapse of the storm helped keep the area from experiencing more severe impacts.
