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 Michael
Once inland, Michael began to rapidly weaken, as it moved over the inner Southeastern United States, with the eye dissipating from satellite view, weakening to a tropical storm roughly twelve hours after it made landfall. However, Michael managed to reach Georgia as a Category 3 hurricane, becoming the first major hurricane to enter the state since 1898. Moving into the Carolinas early on October 11, the inner core of the storm collapsed as the storm's rainbands became prominent to the north of the center. Later that day, Michael began to show signs of becoming an extratropical cyclone, as it accelerated east-northeastward toward the Mid-Atlantic coastline, with cooler air beginning to wrap into the elongating circulation, due to an encroaching frontal zone. Afterward, during the early hours of October 12, Michael began to restrengthen while moving off the coast, due to baroclinic forcing. Shortly afterward, Michael completed its extratropical transition around 09:00 UTC on the same day, as the storm became fully embedded within the frontal zone. Michael subsequently accelerated towards the east, strengthening into a powerful extratropical cyclone by October 14. On October 15, Michael's extratropical remnant approached the Iberian Peninsula and turned sharply towards the southeast, making landfall on Portugal early on October 16. Following landfall, Michael's remnant quickly weakened, dissipating later on the same day.
