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.
2005 Pacific hurricane season
The genesis of Tropical Storm Dora can be attributed to a westward-moving tropical wave that emerged off Africa on June 18. By July 3, the wave passed through the Gulf of Tehuantepec, where broad cyclonic flow began to develop along its axis. Following further organization, the disturbance intensified into a tropical depression by 00:00 UTC on July 4 and further strengthened into Tropical Storm Dora six hours later. The cyclone moved north-northwest and then west-northwest, paralleling the coastline of Mexico under the influence of a subtropical ridge, where landslides and mudslides cut communication to 12 mountain villages. Under a moderate easterly wind shear regime, Dora ultimately changed little in strength, peaking with winds of 45 mph (75 km/h) as the center became obscured on the eastern edge of extremely deep convection. A track over colder waters caused the storm to fall to tropical depression intensity late on July 5 and degenerate into a remnant low by 12:00 UTC on July 6. The low then dissipated six hours later.
