In the United States, damage was not as high as originally expected, mainly because Dennis was more compact and moved more quickly than initially forecast. Dennis made landfall approximately to the east of where Hurricane Ivan had made landfall 10 months before, but did not cause as much damage as Ivan, due to its compact size, quicker path, and because the area was not fully rebuilt from the prior year. Dennis moved about faster than Ivan at landfall, and had hurricane-force winds that only extended from its center, compared to Ivan's 105-mile radius (170 km). During the height of the storm, Dennis produced storm surges as high as in the Apalachee Bay region, and as high as on the Florida Panhandle, and left 680,000 customers without electricity in four southern states.
