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 Otto
Hurricane Otto was the first tropical cyclone since Hurricane Cesar–Douglas in 1996 to survive the crossover from the Atlantic Ocean to the Pacific Ocean. Forming late on November 20 in the southwestern Caribbean Sea, Otto was the fifteenth and final named storm, seventh hurricane and fourth major hurricane of the 2016 Atlantic hurricane season. It quickly intensified into a strong tropical storm the next day, and on November 23–24, rapidly strengthened into a Category 3 major hurricane, the first in the month of November since Hurricane Paloma in 2008, and the latest date an Atlantic hurricane attained such intensity on record. Otto made landfall in Nicaragua at peak intensity on November 24, thus becoming the latest hurricane to make landfall in the Atlantic basin since 1851 when records began. Traveling along the Nicaragua–Costa Rica border, the system rapidly weakened to a tropical storm before emerging over the eastern Pacific Ocean, becoming the final storm of the 2016 Pacific hurricane season as well. Hostile environmental conditions inhibited reorganization, and Otto subsequently degenerated into an elongated trough on November 26.
