mph (75 km/h). Alpha weakened to a subtropical depression and dissipated after entering the northeastern Gulf of Mexico on May 29. Rough seas generated by the storm resulted in two people drowning in Florida and halted work to deepen a harbor at the Mayport Naval Station in Jacksonville. Tides along the Georgia coast reached above normal, which caused some flooding and beach erosion. Wind gusts reached on Saint Simons Island. The winds knocked down trees and power lines, leaving some people without power in eastern Georgia. Damage was minor but widespread in the state, estimated at over $50,000. Moderate rains spread in coastal areas from South Carolina through southern Florida. North Carolina also experienced about $50,000 in damage, mostly due to erosion. Alpha was the first named subtropical storm. Hurricane Agnes A polar front and an upper trough over the Yucatán Peninsula spawned a tropical depression on June 14. The storm emerged into the western Caribbean Sea on June 15, and by the following day, it strengthened into Tropical Storm Agnes. The storm curved northward and brushed western Cuba on June 17. Agnes continued to intensify, and on June 18, it was upgraded to a hurricane. Minimal fluctuations in intensity occurred before the storm made landfall near Panama City, Florida, on June 19. After moving inland, Agnes rapidly weakened and was only a tropical depression when it entered Georgia. Thereafter, weakening slowed as the storm crossed over Georgia and into South Carolina. However, while over eastern North Carolina on June 21, Agnes re-strengthened into a tropical storm, as a result of baroclinic activity. Early the following day, the storm emerged into the Atlantic Ocean before re-curving northwestward and making landfall near New York City as a strong tropical storm. Agnes quickly merged with a non-tropical low pressure system on June 23. Heavy rainfall occurred in western Cuba, causing flooding that destroyed 97 houses, isolated a few cities, and flatted crops in low-lying areas. The storm left seven fatalities. Agnes caused a significant tornado outbreak, with at least 26 confirmed twisters, 24 of them in Florida and the other two in Georgia. The tornadoes alone resulted in over $4.5 million in damage and six fatalities. At least 2,082 structures in Florida suffered either major damage or were destroyed. About 1,355 other dwellings experienced minor losses. Though Agnes made landfall as a hurricane, no hurricane-force winds were reported. Abnormally high tides resulted
