Tropical Storm Alberto was a tropical cyclone that produced extensive and destructive flooding over portions of Alabama, Georgia, and Florida in July 1994. The first named storm of the annual hurricane season, Alberto developed from a tropical wave over the northwestern Caribbean Sea on June 30. Initially a tropical depression, the system moved westward, before curving northwestward on July 1 and entering the Gulf of Mexico. Early on the following day, the depression intensified into Tropical Storm Alberto. Alberto strengthened steadily over the Gulf of Mexico, and by midday on July 3, it peaked as a strong tropical storm with maximum sustained winds of 65 mph (100 km/h). A few hours later, the cyclone made landfall near Destin, Florida, at the same intensity. The system quickly weakened to a tropical depression early on July 4. Thereafter, a high pressure system caused Alberto to drift over west-central Georgia and central Alabama, until the storm dissipated over Alabama on July 7.
In its early and precursor stages, Alberto produced about of precipitation on Cuba's Isla de la Juventud. Striking the Florida Panhandle as a strong tropical storm, the cyclone caused some erosion and wind damage. Additionally, freshwater flooding forced about 3,000 people to flee their homes. Damage in Florida totaled about $80 million. The storm generated heavy precipitation over much of southeastern Alabama. Floodwaters entered hundreds of homes each in Coffee, Dale, Geneva, Henry, and Houston counties. Georgia experienced the worst effects from the storm. Up to of rain fell near Americus. Flooding resulted in the closure of approximately 1,000 bridges, while about of croplands were inundated in Georgia alone. Throughout Alabama, Georgia, and Florida, approximately 18,000 businesses and homes suffered damage or destruction. Alberto was responsible for $1.03 billion in damages (1994 USD) and 33 deaths. Other sources, however, place the damage total from $1.5 billion to almost $2 billion and the death toll closer to 38 people.
Meteorological history
On June 18, radiosonde data from Dakar, Senegal, indicated that a tropical wave emerged into the Atlantic from the west coast of Africa. The wave moved westward for several days, with an associated area of low clouds. Little deep convection developed until June 26, when the wave was situated in just north of Puerto Rico and the Virgin Islands. However, strong wind shear diminished a significant amount of convection while the system crossed the Bahamas on June 28. After crossing Cuba and emerging into the Caribbean Sea by the following day, deep convection quickly redeveloped and became more concentrated as the wave encountered only light vertical wind shear. A reconnaissance aircraft flight into the system on June 30 detected a well-defined circulation. As a result, Tropical Depression One developed just west of Isla de la Juventud at 06:00 UTC. Initially, the depression moved westward at about . However, a low aloft centered over the south-central Gulf of Mexico and a mid-latitude short-wave trough moving eastward across the northern gulf caused the depression to curve northwestward on July 1.
Early on July 2, a reconnaissance aircraft flight into the cyclone indicated that it had intensified into a tropical storm, which was assigned the name Alberto. Later that day, Alberto accelerated somewhat in a northerly direction due to another short-wave trough approaching the central Gulf Coast of the United States, with the storm's forward speed increasing to about . Although the system previously had a rather poor appearance on satellite imagery, the center of circulation became more embedded within the deep convection. At 12:00 UTC on July 3, Alberto attained its peak intensity with maximum sustained winds of 65 mph (100 km/h) and a minimum barometric pressure of . About three hours later, the cyclone made landfall near Destin, Florida, at the same intensity. As the storm moved inland, satellite imagery detected hints of a developing eye feature. However, Alberto rapidly weakened, falling to tropical depression intensity by 00:00 UTC on July 4. After bypassing the short-wave trough, the cyclone's forward progress became blocked by a building high pressure area. As a result, Alberto began drifting over Georgia, executing a small cyclonic loop before entering Alabama. Although having turned very weak, the depression remained a tropical cyclone until its circulation dissipated over Alabama late on July 7.
Preparations On June 30, on the day of Alberto's formation, a tropical storm warning was issued from Puerto Juárez to Mérida, Mexico; the warning was discontinued on July 1. In the United States, a tropical storm watch was posted on July 2 for locations between Sabine Pass, Texas and Pensacola, Florida. The watch was subsequently upgraded to a tropical storm warning from Gulfport, Mississippi, to Cedar Key, Florida; it was soon altered to a hurricane warning. Later on July 3, the hurricane warning was discontinued and replaced with a tropical storm warning, which was lifted at 2100 UTC.
On the Florida Panhandle, residents boarded up windows in anticipation of what was to be a "fury". At gasoline stations, unusually long lines formed, and local stores did increased business in selling emergency supplies. Thousands of tourists along the coast left the region; a local deputy was quoted as estimating that 10,000 people checked out of their hotels early. On Okaloosa Island and Holiday Isle, ground-floor house and businesses were forced to evacuate. Civil-defense authorities evacuated residents from low-lying locations. Then-Governor of Florida, Lawton Chiles, declared a State of emergency for parts of the state, and advised residents along the coast to monitor updates regarding the storm. Over 3,000 people sought refuge in Red Cross shelters along the coast of Florida, westward into parts of Alabama.
Impact
Upon forming, the storm dropped heavy rainfall over parts of Cuba, peaking at .
In the United States, Alberto produced heavy rainfall over the Florida Panhandle, southeastern Alabama, and central and southwest Georgia. Within the three states combined, floodwaters impacted more than of crops. The storm damaged or destroyed approximately 18,000 homes and damaged more than 1,000 roads and 218 dams, many of which failed. Flooding also prompted about 50,000 people to flee their homes. Throughout the United States, Alberto caused about $1.03 billion in damage. A total of 33 deaths occurred, 31 in Georgia and 2 in Alabama.
Florida
At Destin, Florida, sustained winds blew at , while winds gusted to ; however, there was an unofficial report of gusts. There, barometric pressure fell to in association with Alberto. Storm tides of was estimated along the coast of Destin, while tides reached at Panama City. At St. George Island, wind gusts reached . Beach erosion and tidal flooding occurred along the coast. Throughout northwest Florida, of rain fell, with totals as high as . Other precipitation accumulations include at Caryville.
Along the coast, damage was limited to sea walls, piers and boats, and roof damage to some beachfront motels. As the storm progressed inland, it brought down signs, billboards, trees and powerlines, and triggered moderate flooding; about 18,500 customers lost electric power. As a weakened tropical depression, the remnants of Alberto dropped extensive rainfall throughout the region. As heavy rain fell to the north, tremendous volumes of water moved down major river systems into the Florida Panhandle. As a result, there was extensive river flooding that exceeded 100-year events in some locations, particularly along the Apalachicola and Chipola Rivers. The Apalachicola remained above flood stage until August, although in localized areas, flooding persisted until September due to Tropical Storm Beryl. A total of 300,000 chickens and 125 cattle and hogs were lost within the state, and offshore, 90% of the oysters in Apalachicola Bay were lost. The flooding was severe, inflicting $40 million (1994 USD) in damage to infrastructure, $14 million in insured damage, and $25 million in agricultural losses.
Georgia
In Georgia, rainfall from the tropical cyclone peaked at 27.85 in (707 mm) near Americus. Due to a previously stalled cold front, which subsequently caused Alberto to remain stationary, the ground was already saturated with rainfall. Virtually all of the precipitation became instant runoff into streams and rivers. Peak discharges along the Flint and Ocmulgee rivers exceeded 100-year flood levels. At least 100 dams and recreational watersheds suffered severe damage or were destroyed. Many roads were inundated, forcing the closure of 175 roads and 1,000 bridges. Damage to highway infrastructure exceeded $130 million.
Approximately of croplands were submerged, causing about $100 million in damage to agriculture. Fifteen of the United States Geological Survey's (USGS) gaging stations were severely damaged or demolished, forcing data to be collected manually and reported by cellphone. Due to flooded water systems, approximately 500,000 people were temporarily left without drinking water. There were 31 deaths in the state, most of which from cars being swept onto flooded roads or into swollen creeks. With $750 million in damage, Alberto was considered the costliest tropical cyclone in Georgia, until Hurricane Michael in 2018 then later Hurricane Helene in 2024. The flooding was considered the worst in the history of the state.
Southwest Georgia Along the state line with Florida, five counties in southwestern Georgia reported of precipitation. In Bainbridge, the rising Flint River caused 300 residents to evacuate. Although the river crested about lower than initially predicted, flooding moderately or severely damaged approximately 300 homes in Bainbridge, as well as more than a dozen businesses. A local fertilizer plant was also threatened by the swollen Flint River. In the five counties of Brooks, Colquitt, Cook, Thomas, and Worth, the Little and Ochlockonee rivers overflowed their banks, flooding adjacent areas. In Early and Miller counties, of rain fell between July 3 and July 7, while an additional of precipitation was observed from July 10 to July 14. Many low-lying areas were flooded. Seven families were evacuated from their homes in Safford due to flooding. Further north, the Flint River also overflow its banks in Baker and Mitchell counties. Extensive flooding occurred in Newton, with more than $100,000 in property damage. Widespread inundation of crops were reported in both counties.
In Dougherty County, the Flint River exceeded its banks, forcing over 20,000 residents to evacuate. Five deaths were reported in the county, with four people drowning in the river and another from a woman being trapped in her home for several days. The city of Albany was cut in half by the flooding, and hundreds of caskets were disinterred and floated away, sometimes disintegrating into the water. Several locations along State Route 37 flooded in Fort Gaines, a city in Clay County. To the north in Randolph County, Cuthbert recorded of rainfall during a 5-day period. Many streets in the city were flooded, including two portions of U.S. Route 82 and a part of State Route 266. In Terrell County, the sheriff's department reported that many roads were inundated due to swollen creeks and streams. A number of homes and businesses suffered an extensive impact, with up to several million dollars in many. A woman was killed in Dawson after her car was swept off the road into Chickasawhatchee River.
