Hurricane Gerda was an atlantic tropical cyclone that formed during the 1969 Atlantic hurricane season. The seventh named storm, fifth hurricane and third major hurricane of the 1969 season.[1] Gerda formed on September 6 and crossed Florida as a tropical depression. Gerda later then became a tropical storm while moving northeast and reaching hurricane status on September 8. Gerda brushed past the Outer Banks of North Carolina before reaching maximum intensity of 125 mph and a low barometric pressure of 979 millibars. On September 10, Gerda made landfall near Eastport, Maine and became extratropical the following day.

[edit] Storm history
A tropical wave moved off the eastern coast of Africa on August 21 and moved westward across the Atlantic Ocean without development. On September 3, the disturbance merged with a dissapating upper level low pressure system over Hispanola and Puetro Rico and developed an increasing cloud mass as it continued westward. As the the disturbance crossed the Bahamas, satalite imagery showed the disturbance gaining a distinct circulation on September 5. On September 6, the disturbance became Tropical Depression before it made landfall in southeastern Florida on the same day.[2]
After crossing Florida, the depression drifted northeastward back over the western Atlantic Ocean on September 7. As the system headed northeastward, hurricane hunter aircraft recorded the winds of 45 mph and a barometric pressure fell to 1000 millibars. That allowed forecasters at the National Hurricane Center upgraded the system to tropical storm status and named it Gerda. Gerda continued to moved rapidly northeast in response to an approaching trough and the storm reached hurricane status on September 8. Gerda's foward speed approached 40 mph as the eye of the hurricane passed 50 miles east of Cape Cod on September 9. At that time, the hurricanes winds reached a peak intensity of 125 mph. Because the storm was interacting with the trough to the west and was moving rapidly northeastward, the result was the minimum central barometric pressure was an unusually high 979 millibars. Gerda later made landfall near Eastport, Maine later that day.[2]Gerda then became extratropical as it crossed into Canada as a 45 mph extratropical storm on September 10. The storm later dissapated the following day.[3]
