Tropical Depression One (1979)

On June 12, the depression peaked with maximum sustained winds of 35 mph (55 km/h), never having reached tropical storm status.

Early on June 14, the depression emerged into the western Atlantic Ocean and then moved parallel to the east coast of Florida for a few days.

The slow movement of the depression to the west of Jamaica resulted in torrential rainfall, peaking at 32 in (810 mm) in Friendship, a city in Westmoreland Parish.

The depression also brought heavy precipitation to Cuba and the Bahamas, while farther north, light rainfall and rough seas plagued the East Coast of the United States.

However, by June 11, the system began to interact with a stationary trough of low pressure in the western Caribbean Sea.

[1] Based on ship and land observations,[2] a tropical depression developed at 12:00 UTC that day while located about 230 miles (370 km) south of Grand Cayman.

[3] Minimal intensification occurred, as satellite imagery, weather stations, and a reconnaissance aircraft indicated the depression remained below tropical storm status.

[3] Early on June 13, satellite and weather radar showed heavy rainbands moving across Jamaica and eastern Cuba.

Operationally, the system was thought to have made landfall in east-central Florida, but later analysis revealed that the center remained over water.

[3] Its remnants continued northeastward across the Southeastern United States, the Mid-Atlantic, and New England until dissipating fully on June 18.

[10] Extensive impact to property was reported, including to electricity, telephones, buildings, and railways, with a "conservative" estimate of $39.3 million in damage.

[1] Along the coast, waves reached 13 ft (4.0 m) in height, strong enough to tear a boat from its mooring at Surfside Beach.
