Hurricane Gerda (1969)
Hurricane Gerda was a North Atlantic tropical cyclone that formed during the 1969 Atlantic hurricane season. It was the seventh named storm, fifth hurricane and third major hurricane of the 1969 season. Gerda formed on September 6 and crossed Florida as a tropical depression. Gerda later became a tropical storm after making a hard right turn and 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 (205 km/h) and a low barometric pressure of . On September 10, Gerda made landfall near Eastport, Maine, and became extratropical the following day.
Hurricane Gerda brought light rain across southern Florida and moderate to heavy rain across eastern North Carolina and New England, causing minor damage to trees and powerlines. The highest amount of rain was which was recorded in South Wellfleet, Massachusetts on Cape Cod. There were no fatalities or injuries from Gerda although planes at Otis Air Force Base were moved to their hangars and two ships from Naval Station Newport left their berth to ride out the storm.
==Meteorological 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 dissipating upper level low pressure system over Hispaniola and Puerto Rico and developed an increasing cloud mass as it continued westward. As the disturbance crossed the Bahamas, satellite imagery showed the disturbance gaining a distinct circulation on September 5. On September 6, the disturbance became a Tropical Depression before it made landfall in southeastern Florida on the same day.
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 winds of 45 mph (72 km/h), and barometric pressure fell to . Forecasters at the National Hurricane Center upgraded the system to tropical storm status and named it ''Gerda''. Gerda continued to move rapidly northeast in response to an approaching trough and the storm reached hurricane status on September 8. Gerda's forward speed approached 40 mph (64 km/h) as the eye of the hurricane passed 50 miles (80 km) east of Cape Cod on September 9, with maximum sustained winds of 125 mph (205 km/h). 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 .〔 Gerda later made landfall near Eastport, Maine later that day as a Category 2 hurricane, one of the strongest to ever make landfall in the state.〔 Gerda then became extratropical as it crossed into Canada as an 80 mph (130 km/h) extratropical storm on September 10. The storm later dissipated the following day.
