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.
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.
