Delaware River Flood of 2004

Hurricane Ivan, an obnoxious storm if ever there was one . . .
Like the Party Guest from Hell, Ivan just didn't know when it was time to leave. Ivan was the ninth named storm, the sixth hurricane, and the fourth major hurricane of the 2004 Atlantic hurricane season. It was a Cape Verde-type hurricane, meaning it had its origins near the Cape Verde islands just off the west coast of North Africa.

Ivan reached Category 5 strength at his peak, and early in his development reached unprecedented intensity at low latitudes—Category 4 at only 10.6° N

After being briefly downgraded to Category 3 intensity, Ivan struck Grenada directly at mid-day on September 7 with Category 3 winds.
He travelled across the Caribbean Sea, reaching Category 5 intensity before passing close to the Jamaican coast and Grand Cayman Island, crossing the western tip of Cuba.
After moving into the eastern Gulf of Mexico, Ivan's strength lessened to a Category 4.
He continued on a track towards the north-northwest, making landfall in the U.S. near Gulf Shores, Alabama.
As Ivan approached landfall, Florida Lt. Governor Toni Jennings described the storm as "the size of Frances but [with] the impact of Charley."
After landfall, Ivan moved north and then turned east, bringing heavy rainfall to large areas of the southeastern United States.
Though Ivan only reached as far north as Virginia, he came close enough to inundate the Delaware Valley with 4-7 inches of rain.
He then looped south and through Florida, and regenerated into a tropical storm for a short time in the gulf and moved into Louisiana and Texas.
