Tropical Storm Danny was a weak and short-lived tropical cyclone that caused minor damage to the U.S. states of South Carolina and Georgia. The fourth named storm of the 2021 Atlantic hurricane season, the system formed from an area of low-pressure that developed from an upper-level trough over the central Atlantic Ocean on June 22. Moving west-northwestward, the disturbance gradually developed as convection, or showers and thunderstorms, increased over it. Although it was moving over the warm Gulf Stream, the organization of the disturbance was hindered by strong upper-level wind shear. By 18:00 UTC of June 27, as satellite images showed a well-defined center and thunderstorms, the system was upgraded to a tropical depression by the National Hurricane Center (NHC). At 06:00 UTC on the next day, the system further strengthened into Tropical Storm Danny east-southeast of Charleston, South Carolina. Danny continued its track towards South Carolina while slowly strengthening, subsequently reaching its peak intensity at that day of 45 mph (72 km/h) and a minimum central pressure of 1,009 mbar (29.8 inHg) at 18:00 UTC. Danny then made landfall in Pritchards Island, north of Hilton Head, in a slightly weakened state at 23:20 UTC on the same day, with winds of 40 mph (64 km/h) and indicating that Danny weakened prior to moving inland. The system then weakened to a tropical depression over east-central Georgia, before dissipating shortly afterward.
Danny was one of three systems to make landfall on the U.S. state of South Carolina in the month of June, the others being Hurricane One in 1867 and Tropical Depression One in 1979. Heavy rainfall was recorded in some portions of Georgia and South Carolina, causing minor flooding. In addition to flooding, impacts were also limited to some fallen trees and lightning strikes. Ten rescues were required on two different beaches on North Carolina due to rip currents. No deaths were reported due to Danny, and the damage from it in the Southeastern United States totaled $5,000 (2021 USD).
