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.
Hurricane Irma
Georgia Governor Nathan Deal declared a state of emergency initially for all six coastal counties on September 6; however, the state of emergency was expanded to cover 30 counties in southeast and east central Georgia, and Governor Deal ordered mandatory evacuations for all areas east of Interstate 95 on September 7. Contraflow lane reversal for Interstate 16 took effect on September 9 at 8:00 a.m. from Savannah to Dublin, Georgia. On September 8, Governor Deal further expanded the state of emergency to cover 94 counties south of the Atlanta metropolitan area, with mandatory evacuations expanded to include the entirety of Chatham County as well as low-lying areas west of I-95. In total, 540,000 people on the Georgia coast were ordered to leave. On September 10, the state of emergency for Georgia was extended to cover the entire state, while Atlanta was placed under its first-ever tropical storm warning.
