Tropical Storm Hanna caused only minimal damage to the South Carolina coast, as it scraped by offshore on September 5. The heaviest rains occurred in Charleston, Horry , and Marion Counties. Several streets in downtown Charleston were flooded temporarily. Only minor beach erosion was reported along the South Carolina coast due to the offshore winds from Hanna.

The South Carolina Emergency Management Division activated the Emergency Operations Center on September 3 when the National Hurricane Center began forecasting Tropical Storm Hanna to make landfall on the South Carolina coast. The Emergency Operations Center remained staffed until September 6. There were no mandatory evacuations. The Governor issued a voluntary evacuation order September 4 for Georgetown and Horry County coastal areas. Several emergency shelters were opened when Hanna threatened to make landfall August 31.
