Final Report of the Disaster Survey Team on the Events of Agnes: A Report to the Administrator [open pdf - 0B]
"Though Hurricane Agnes, the first Atlantic hurricane of the 1972 season, was not an unusual storm in the beginning, it eventually caused what has been termed the greatest natural disaster ever to befall this Nation. Formed from a depression off the coast of Yucatan on June 15, the storm developed and moved slowly northward, dumping large amounts of rain on western Cuba and spawning tornadoes over the Florida peninsula and Keys. The sustained winds in Agnes never reached more than minimal hurricane intensity, but its circulation and precipitation patterns covered extremely large areas. When it crossed the Florida coast near Panama City on June 19, Agnes had degenerated to a tropical storm. The storm then moved over Georgia and out into the Atlantic, up the coast to New York, and westward over New York and Pennsylvania (fig. 1). Along the way, Agnes regenerated in strength, produced excessive amounts of precipitation, and caused rivers and streams from the Carolinas to New York to rise to record or near-record stages. A record $3.5 billion in property damage was caused by floods and flash floods, and 118 persons were killed."
