. Initial forecasts predicted for great intensification, including one forecast for the depression to strengthen to a hurricane within three days. However, the depression remained disorganized, and slowly intensified to attain tropical storm status on August 22.

After becoming a tropical storm, Edouard quickly strengthened due to the establishment of an upper-level anticyclone over the storm. The storm moved to the west in response to a strong subtropical ridge to its north, and Edouard strengthened into a hurricane on August 23. Due to very favorable conditions, the hurricane rapidly strengthened on August 24 and August 25 to peak as a 145 mph (230 km/h) Category 4 hurricane on the Saffir-Simpson Scale

 on August 28. For three days during this time, Edouard maintained Category 4 intensity, though weakened late on August 28 due to an eyewall replacement cycle and vertical shear.

Late on August 29, Hurricane Edouard developed three concentric eyewalls, an unusual occurrence coinciding with an increase in strength to 140 mph (220 km/h). A mid-tropospheric trough turned the hurricane to the north to an area of unfavorable conditions, and Edouard weakened to a Category 3 hurricanes on August 31. On September 1, the hurricane passed about mid-way between Bermuda
