Cuba

The rainbands of Alberto produced heavy rainfall and flash flooding across western Cuba. The rainfall peaked at 39.84 inches (1,012 mm), the fourth highest rainfall total in the country since 1963.^[5] More than 50,000 were forced to evacuate from the resulting floods,^[6] which were described as the worst flooding in the northwestern portion of the country since 1950.^[7]

Hurricane Alberto damaged a total of 8,745 houses in the country.^[8] In Pinar del Río Province, 71 homes were destroyed,^[6] and across the nation hundreds of people were left homeless.^[9] 83 buildings were collapsed in the capital city of Havana,^[6] while six factories in Havana Province received damage.^[10] The passage of Alberto left several districts in Havana without electricity, telegraph, telephone, and mail service. The Cuban military was deployed to rescue those trapped in flooded homes and also to remove fallen trees.^[6] Agricultural damage included about 250,000 downed banana trees^[11] and 400 drowned cattle.^[12] Heavy rainfall continued for weeks after the passage of Alberto, resulting in severe damage to the tobacco crop. Subsequent winds and rains destroyed storage sheds which ruined 1.8 million lb. (900,000 kg) of the recently finished harvest; 2.6 million lb. (1.3 million kg) of tobacco leaves were also damaged.^[12] Two days after its closest approach, the death toll in Cuba reached 11,^[13] and a day later it was raised to 23 fatalities.^[9] The final death toll was reported as either 23^[2] or 24, with one report indicating 17 people missing;^[5] Pinar del Río Province reported at least 20 deaths and Havana reported three casualties.^[6] Damage was estimated at $85 million (1982 USD$, 258 million 2024 USD).^[14]

Florida

Rainfall Summary for Hurricane Alberto

Due to its sudden development and project track into southwest Florida, the National Hurricane Center issued a tropical storm warning and hours later a hurricane warning from the Dry Tortugas to Marathon in the Florida Keys and along the southwestern coastline northward to Fort Myers. A hurricane watch was also issued from Marathon to Jupiter Inlet.^[3] At the time of the issuance of the hurricane warning, Alberto had been moving steadily northeastward; extrapolating its motion indicated a landfall on Key West within 12 hours and a mainland landfall at Key Largo within 24 hours. Additionally, most computer models predicted Alberto to continue northeastward across south Florida. Only one model, not available until later, suggested a weakness in steering currents that would prevent a Florida landfall.^[15]

Officials ordered mandatory evacuations along the southwest coast of Florida. More than 1,000 left their homes to stay in nine emergency shelters.^[13] Air Florida canceled all flights from Miami to Key West. Many residents in the lower Florida Keys were unable to evacuate to the mainland, with about 50 people in Key West evacuating to four emergency shelters set up in the city. Officials closed schools in Monroe County at midday on June 3 and also sent all nonessential city and county employees home.^[16]

Gale-force winds and heavy rainfall were reported in the lower Florida Keys;^[2] Key West reported 6.25 inches (159 mm) during a 24-hour period, with the maximum reported winds at a land station being 70 mph (110 km/h) in the Dry Tortugas.^[15] Moderate rainfall was reported throughout southern Florida and the eastern Florida Keys, as well, peaking at 16.47 inches (418 mm) at Tavernier.^[17] Alberto spawned three tornadoes and a waterspout in the Florida Keys,^[18] one of which at Stock Island which damaged several boats.^[13] One of the three tornadoes picked up a moving car and lightly injured the driver. Another knocked down two telephone poles on the Overseas Highway, which resulted in an hour traffic delay.^[16] Damage from the tornadoes totaled $275,000 (1982 USD, $620,000 2010 USD).^[19][20]
