In Florida, a moderate storm tide caused coastal damage and flooding, while Alberto's outer rainbands produced several tornadoes.

In early June 2006, an area of convection persisted across Central America and the western Caribbean in association with a broad, nearly stationary trough of low pressure.

[3] The disturbance moved slowly north-northwestward, and development was initially inhibited by marginally favorable upper-level winds and land interaction.

[1] The depression tracked to the northwest through the Yucatán Channel into an area of increased wind shear, which left the center exposed and elongated.

The depression intensified into Tropical Storm Alberto early on June 11 about 260 miles (420 km) southwest of the Dry Tortugas, based on Hurricane Hunters' reports of flight level winds of 50 mph (80 km/h) in a few convective bands.

[9] On June 12, the circulation abruptly reformed under the area of deepest convection, which coincided with the storm's passage over the loop current; consequentially, Alberto quickly strengthened to reach peak winds of 70 mph (110 km/h) about 220 miles (350 km) west-northwest of Tampa, Florida.

[10] The storm maintained peak intensity for about 18 hours,[1] and while accelerating northeastward, Alberto's convection diminished as the cloud pattern became elongated.

[11] On June 13, dry air became entrained in the circulation, leaving the center exposed from the convection and the wind field greatly broadened.

[13] Alberto continued to weaken, and made landfall at about 1630 UTC on June 13 with 45 mph (72 km/h) winds in Taylor County, Florida, about 50 miles (80 km) southeast of Tallahassee.

[19] The extratropical storm turned to the east-northeast and later to the east as it continued its rapid forward motion, and on June 19 the remnants of Alberto merged with an approaching cold front near the British Isles.

[20][21] The National Hurricane Center recommended tropical storm warnings for the Isle of Youth and the Pinar del Río Province early on June 10, but they were not issued by the Cuban government.

A tropical storm warning was also issued from Flagler Beach, Florida to the mouth of the Santee River in South Carolina.

[1] As the storm moved inland, local National Weather Service offices issued flood watches for portions of North Carolina, Virginia, and the Delmarva Peninsula.

[16] While Alberto was becoming extratropical over land, the Canadian Hurricane Centre issued gale warnings for offshore waters of Nova Scotia,[27] and later for Newfoundland.

In addition, the Atlantic Storm Prediction Center issued inland wind warnings for coastal regions of Nova Scotia.

[25][34] Across coastal areas, the storm surge flooding caused minor damage to dozens of homes and closed several roads.

[16] Alberto produced a storm tide of 8.53 feet (2.60 m) at Fort Pulaski National Monument, causing some beach erosion along the coastline.

Storm tides reached 7.81 feet (2.38 m) above the mean low-level water mark along Fripp Island, leading to some beach erosion along portions of the coastline.

[37] The remnants of Alberto dropped heavy precipitation across North Carolina, including a nationwide high of 7.16 inches (182 mm) at the Raleigh National Weather Service Office.

[43] The extratropical remnant of Alberto produced strong winds across the Canadian Maritimes, including gusts of 74 mph (119 km/h) in the Municipality of the District of Barrington of Nova Scotia.
