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 (100 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, $104 million 2017 USD).
By early on October 6, a low pressure area and circulation persisted over eastern Cuba in the middle levels of the atmosphere. The low drifted westward, and interacted with Hurricane Klaus to its east. Initially cold-core in nature, the system gradually built downward to the surface, and on October 9, the low developed a low-level circulation; at 1200 UTC the National Hurricane Center classified it as Tropical Depression Fifteen while located near the Cuban city of Caibarién, though the cyclone was initially subtropical in character. To its east, Tropical Storm Klaus continued to weaken; the depression absorbed most of Klaus and became the dominant system. The storm tracked parallel to the coast of Cuba before veering northward and crossing the Florida Keys, where it intensified into Tropical Storm Marco about 35 mi (55 km) south-southeast of Key West, Florida.
