Tropical Storm Marco was the only tropical cyclone to make landfall on the United States during the 1990 Atlantic hurricane season. The 13th named storm of the season, Marco formed from a cold-core low pressure area along the northern coast of Cuba on October 9, and tracked northwestward through the eastern Gulf of Mexico. With most of its circulation over the western portion of Florida, Tropical Storm Marco produced 65 mph (105 km/h) winds over land. However, it weakened to a tropical depression before moving ashore near Cedar Key. The cyclone combined with a cold front and the remnants of Hurricane Klaus to produce heavy rainfall in Georgia and the Carolinas. After interacting with the nearby Hurricane Lili, Marco continued northward until being absorbed by a cold front on October 13.
In Florida, the cyclone triggered flooding of some houses and roadways. Rainfall across its path peaked at 19.89 inches (505 mm) in Louisville, Georgia, though several locations received over 10 inches (250 mm) of precipitation. The flooding caused a total of 12 deaths, mostly due to drowning, as well as $57 million in damage (1990 USD$, 133 million 2024 USD).
