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.
