Tropical Storm Alberto was a destructive pre-season tropical cyclone which caused $125 million in damage in the Gulf Coast of the United States in May 2018, the costliest for any pre-season tropical cyclone. The first storm of the 2018 Atlantic hurricane season, Alberto developed on May 25 near the Yucatán Peninsula as a subtropical cyclone. As it entered the Gulf of Mexico, Alberto intensified and transitioned into a tropical cyclone. Early on May 28, Alberto reached its peak intensity, with maximum sustained winds of 65 mph (100 km/h) and a minimum pressure of 990 mbar (hPa; 29.23 inHg). Afterward, however, dry air caused Alberto to weaken before it made landfall near Laguna Beach, Florida, with winds of 45 mph (75 km/h). Alberto maintained a compact area of thunderstorms as it progressed through the central United States, entering southern Michigan as a tropical depression on May 31. That day, Alberto weakened further and dissipated over Ontario.
Along its path, Alberto dropped heavy rainfall, mainly to the east of its storm path. In Cuba, storm flooding killed ten people, and also damaged houses, roads and crops. Floodwaters caused an oil spill in Cienfuegos Bay. In the United States, Alberto caused about $125 million (2018 USD) in damage, as well as eight deaths. Five fatalities occurred in North Carolina, three of which were a result of landslides, and the other two from fallen trees. Flooding was responsible for the deaths of three people in Virginia. The storm caused coastal flooding along the United States Gulf Coast, most significantly in Florida where it moved ashore.

Alberto produced heavy rainfall along the Yucatán Peninsula, causing flooding in Mérida, Yucatán.[14]
During its formative stages, Alberto also dropped heavy rainfall across much of western Cuba, peaking at 14.41 inches (366 mm) in Heriberto Duquezne, Villa Clara. At least 7 in (180 mm) of rainfall fell in Pinar del Rio, Artemisa, Matanzas, Cienfuegos, Sancti Spíritus and Ciego de Avila provinces. The rain caused flooding and landslides across central and western Cuba, killing ten people due to drowning, and forcing at least 40,000 people to evacuate their homes. Zaza Reservoir, Cuba's largest reservoir, rose to its second-highest level on record.[1] Storm surge and abnormally high tides caused coastal flooding on Isla de la Juventud, and from Pinar del Río to Mayabeque Province.[15]
Alberto's flooding in Cuba forced more than 52,000 people to leave their houses. Power cuts affected nearly 60,000 people.[16] Nationwide, the storm damaged 5,218 houses,[17] as well as 9,582 hectares (23,680 acres) of crops. Elevated water levels in Zapata Swamp submerged hundreds of houses, with floodwaters persisting even 18 days after the storm.[18] Flooding damaged roads and bridges, isolating some villages and impeding transportation and relief aid.[1] In Taguasco, a bridge across the Zaza River was swept away,[19] with reconstruction commencing a few weeks after the storm.[17] Floodwaters inundated numerous streets, including Autopista A1 in Villa Clara Province, forcing authorities to close the road.[19] At the Cienfuegos oil refinery, the water treatment pond overflowed amid storm flooding, which spilled about 12,000 m3 (420,000 cu ft) of oily water into Cienfuegos Bay.[1] Despite cleanup efforts, the oil spill negatively affected the area's ecosystem.[18] After the storm, officials provided food and building supplies to residents who sustained storm damage,[17] and planted crops to regrow the damaged supply.[18]
United States
Across the United States, Alberto caused about $125 million in wind and water damage, and was responsible for eight deaths. In North Carolina, landslides killed a woman in Polk County, North Carolina and two women near Boone when a gas leak caused an explosion.[1] WYFF News 4 anchor Mike McCormick and photojournalist Aaron Smeltzer died while covering the storm after a tree fell onto their vehicle on U.S. Route 176.[20] In Virginia, flooding killed two people near Charlottesville and one person in Madison County.[1]
Alberto dropped heavy rainfall across Florida for several days. This contributed to Florida having the wettest May on record in 2018.
West of the storm's landfall, Alberto flooded coastal areas of Alabama, Mississippi and Louisiana as the storm moved ashore.
