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.

The effects of Hurricanes Cleo, Dora, and Isbell combined were devastating to Florida. Cleo also brought destruction to portions of the Caribbean, especially Guadeloupe and Haiti. After moving inland, Cleo brought flooding to states such as Virginia. Overall, the storm caused 219 deaths and about $187.5 million in damage. Dora lashed much of North Florida and southeastern Georgia with hurricane-force winds, leaving five fatalities and around $280 million in damage. In October, Isbell brought strong winds and several tornadoes to Florida, as well as flooding to Cuba and The Carolinas. Isbell killed seven people and left approximately $30 million in damage.
