late on September 13, 2004.
Ivan gradually turned toward the north as it moved through the Gulf of Mexico on September 14 and 15, 2004. It maintained
a Category 4 status during the few days proceeding land fall. Ivan decreased slightly in intensity, to a strong Category 3 storm,
just before making land fall. The center of Hurricane Ivan moved on shore near Gulf Shores, Alabama, at around 300 AM on Thursday,
September 16, 2004. maximum sustained winds at landfall were estimated to be near 130 MPH, with a minimum pressure of 943 millibars.

widespread heavy rain affected much of the southern Appalachians.
The system remained a Tropical Depression status as it slowly moved northeast across northwestern Georgia and
eastern Tennessee during Thursday night and Friday morning. By 1100 AM, Friday, September 17, the depression was
located 45 miles east of Knoxville, Tennessee. Widespread heavy rain affected western North Carolina Thursday night and Friday.
Wind gusts reached between 40 and 60 MPH across the higher elevations of the Appalachians. Numerous trees were downed and flooding

As the depression moved across northeastern Tennessee and southwestern Virginia Friday afternoon, the Piedmont
of North Carolina remained in the warm sector of the storm. As late morning and afternoon temperatures reached
the 80s, several rain bands became enhanced and produced damaging winds and several tornadoes. Tornadoes, varying
in intensity from F0 to F2, touched down producing damage to homes, businesses, and trees in Guilford, Rockingham,
Moore, and Chatham Counties.
Damaging winds were reported with several of the rain bands including a 79 MPH wind gust at the Raleigh-Durham
