1964 Atlantic hurricane season
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 . Two hours later, Dora weakened to a Category 2 hurricane. However, deterioration then slowed, with the hurricane falling to tropical storm intensity 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 became extratropical several hours later. The remnants of Dora moved rapidly northeastward and dissipated offshore Newfoundland early on September 16.
Hurricane Georges
Hurricane Georges reached the Straits of Florida on September 24, and as it had done earlier in its lifetime, quickly restrengthened to Category 2 status on the September 25 due to warm water temperatures and little upper-level shear. It continued to the west-northwest, and struck Key West later on September 25 with winds of 105 mph (165 km/h). Despite moving over warmer water, Georges only managed to peak at 110 mph (175 km/h) in the Gulf of Mexico, likely due to its disrupted inner core. A mid-tropospheric anticyclone pushed the hurricane slowly north-northwestward, forcing Georges to make its seventh and final landfall near Biloxi, Mississippi on September 28. Within 24 hours, Georges had weakened to a tropical depression, and due to weak steering currents the storm looped over southern Mississippi, then drifted to the east. The weak circulation moved eastward over the interior of the Florida Panhandle, and dissipated on October 1 near the Florida/Georgia border.
