Tropical Storm Marco was the only tropical cyclone to make landfall in 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. Its circulation produced 65 mph (100 km/h) winds over the western portion of Florida before weakening to a tropical depression and 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. In Florida, the cyclone triggered flooding of some roadways. Rainfall across its path peaked at 19.89 inches (505 mm) in Louisville, Georgia. The flooding caused 12 deaths, mostly due to drowning, as well as $57 million in damage. (Full article...)
