TAMPA, Fla. (WFLA) — The fourth named storm of the season officially formed off the coast of South Carolina on Monday afternoon, made landfall hours later and then weakened to a tropical depression.

The National Hurricane Center issued an updated statement at 3 p.m., an hour after its regularly-scheduled 2 p.m. advisory, to say Tropical Depression Four had strengthened to become Tropical Storm Danny.

“Doppler radar data from Charleston, South Carolina, along with preliminary data from an Air Force Reserve reconnaissance aircraft, indicate that the depression has strengthened and is now Tropical Storm Danny,” the update said.

It officially made landfall just north of Hilton Head Island shortly before 8 p.m. Monday evening. By 11 p.m., it had weakened to a tropical depression.

Danny could bring heavy rainfall to coastal South Carolina and Georgia, and inland across Georgia and into Alabama. The NHC says isolated flooding is possible across urban areas of the coasts of South Carolina and Georgia.
