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 Dora (1999)
Late on August 8, the storm consisted primarily of central dense overcast, but minimal banding features. At 00:00 UTC on August 9, Dora intensified into a Category 2 hurricane. Several hours later, an eye with a diameter of about 6–12 mi (10–19 km) developed, and the cyclone organized further. Thus, it was predicted that Dora would soon reach Category 3 intensity. The storm strengthened into a Category 3 hurricane around 00:00 UTC on August 10. In a forecast discussion by the National Hurricane Center nine hours later, it was noted that a mid-troposhperic ridge would track eastward, thus causing Dora to move in a west-northwestward motion. However, the hurricane instead continued westward or slightly north of due west. Late on August 10, deep convection significantly expanded and became more symmetric, while Dvorak intensity estimates indicated that Dora reached Category 4 intensity. A predicted weakening trend led the National Hurricane Center to note that Dora was likely near peak intensity.
