Tropical Storm Edouard was the fifth named storm of the 1990 Atlantic hurricane season. Edouard had a non-tropical origin, and was a high latitude storm that formed on August 2 southwest of the Azores. Edouard was never a very tropical system, but because deep convection developed and organized around the center for a time, it was designated a tropical cyclone. Edouard moved slowly and erratically across the northeastern Atlantic Ocean until it became extratropical on August 11. Edouard caused no known damage, and no known fatalities.
