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.

Hurricane Dora (1999)
Hurricane Dora was one of few tropical cyclones to track across all three north Pacific basins. The fourth named storm, third hurricane, and second major hurricane of the 1999 Pacific hurricane season, Dora developed on August 6 from a tropical wave to the south of Mexico. Forming as a tropical depression, it gradually strengthened and was upgraded to Tropical Storm Dora later that day. Thereafter, Dora began heading in a steadily westward, before becoming a hurricane on August 8. Under warm sea surface temperatures (SST's) and low wind shear, the storm continued to intensify, eventually peaking as a 140 mph (220 km/h) Category 4 hurricane on August 12. While passing south of Hawaii, Dora significantly fluctuated in intensity, ranging from peak intensity as a Category 4 hurricane to a low-end Category 1 hurricane. While crossing the International Dateline on August 20, Dora weakened to a tropical storm. After weakening to a tropical depression on August 22, Dora dissipated on August 23 while centered several hundred miles north of Wake Island.
