Hurricane Dora
Later on September 7, Dora re-strengthened into a Category 3 hurricane. Approaching the east coast of Florida, Dora's motion became erratic, making a few cyclonic loops. Around 04:00 UTC on September 10, the hurricane made landfall near St. Augustine, Florida, with winds of 115 mph (185 km/h). Two hours later, Dora weakened to a Category 2 hurricane. However, deterioration then slowed, with the hurricane falling to tropical storm intensity over Jefferson County on September 11. Dora then briefly drifted over southwestern Georgia, until turned east-northeastward late the next day. Early on September 14, the storm re-emerged into the Atlantic Ocean near Cape Hatteras, North Carolina, and transitioned into an extratropical cyclone several hours later. The remnants of Dora moved rapidly northeastward and dissipated offshore Newfoundland early on September 16.
History of Jacksonville, Florida
Dora was the only storm in recorded history to affect Jacksonville with hurricane-force winds, though the city has been affected by weaker storms as well as hurricanes that lost intensity before reaching the area. In September 1999, after Hurricane Floyd struck the Bahamas, over one million Floridians were evacuated from coastal areas, many of them from Jacksonville. Mayor John Delaney announced the mandatory evacuation of the Jacksonville Beaches and other low lying neighborhoods early on September 14; in total, nearly 80,000 Jacksonville residents left their homes. Ultimately the storm turned northward 125 miles off the coast, causing only minor damage in Jacksonville and the southeastern US before making ground in North Carolina. In September 2017, Jacksonville experienced record flooding from Hurricane Irma.
