Hurricane Dora
Around 12:20 a.m. EST on September 10, Hurricane Dora made landfall about north of St. Augustine, Florida, with sustained winds between 115 and 125 mph (185 and 205 km/h). Although estimated to have been a Category 3 at landfall, the highest winds onshore were believed to have been in the Category 2 range. Striking northeastern Florida, Dora became the first tropical cyclone on record to make landfall in the region. Once onshore the storm gradually weakened, losing hurricane status about 24 hours later, and began a gradual turn towards the northeast. During the morning of September 12, Dora became almost stationary over the southern border between Alabama and Georgia. However, the storm rapidly accelerated and re-emerged into the Atlantic Ocean on September 14 near the Outer Banks of North Carolina. Hours after moving over water, the system transitioned into an extratropical cyclone. The remnants of Dora were last mentioned on September 16 off the northeast coast of Newfoundland.

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.
