The effects of Hurricane Dennis in Georgia included two deaths and $24 million (2005 USD) in damage. On June 29, 2005, a tropical wave emerged off the west coast of Africa. Gradually, the system organized on July 2 and formed a broad low pressure area. The system continued to organize, and it became a tropical depression on July 4. Tracking westward, it became a tropical storm on July 5 and a hurricane on July 7. Dennis rapidly intensified to attain Category 4 status on the Saffir-Simpson Hurricane Scale before making landfall on Cuba. The storm weakened to Category 1 status before re-emerging in the Gulf of Mexico and intensifying. Dennis made landfall on the Florida Panhandle on July 10, then tracked over southeast Alabama.

Dennis had moderate effects in the state, primarily from flooding. One rainband in particular stalled in southwest portions of the state and produced 4–8 inches (100–200 mm) of rain, with isolated reports of up to 12 inches (300 mm). Flash flooding occurred in several areas, damaging hundreds of homes and businesses. Light to moderate wind gusts of 42 miles per hour (68 km/h) combined with saturated ground downed several trees, one of which fell into a house, killing a man near Atlanta. A man also died while working with utility crews to restore power. One tornado was reported, downing 200 trees.

Preparations

In anticipation of the storm, the National Weather Service placed much of central, north and western Georgia under a flood watch. A wind advisory was also in effect for Clayton, Cobb, DeKalb and Fulton Counties. As the hurricane's outer rainbands approached the state, a tornado watch was put into effect for central portions of the state.[1] The Red Cross provided 80 shelters in the state, in addition to hundreds of volunteers.[1] Due to large evacuations in the state, construction projects on Interstates 75, 85, and 185, were postponed.[2]
