Around 70,000 people in or near West Palm Beach lost electricity after falling trees downed around one-third of Florida Power & Light's main feeder lines. Abnormally high tides damaged docks and piers, while also flooding portions of South Ocean Boulevard between Lake Worth and Lantana. In Palm Beach, several boats moored in the Lake Worth Lagoon capsized. Damage in the county totaled approximately $30 million, most of it incurred to crops. Farther north, the storm deroofed a few structures and flooded some buildings in the Treasure Coast, including the Stuart City Hall. A 450-ft (140-m) crane was snapped in two at the St. Lucie Nuclear Power Plant. In Vero Beach, a tornado caused major damage to a restaurant and deroofed a condominium and apartment building. Some clapboard-style homes in the county suffered major damage, especially in Gifford and other low income communities. Heavy rains inundated portions of State Road 60 with up to of water between Interstate 95 and Yeehaw Junction because the St. Johns River marsh had difficulty draining. Two tornadoes in Brevard County caused damage. The first twister severely impacted or destroyed about 50 mobile homes and a condominium complex in Melbourne Beach and a shopping center in Palm Bay after crossing the Indian River. The shopping center alone sustained about $1.5 million in damage. Another tornado was spawned in Cocoa, damaging a few roofs. Georgia Hurricane David made landfall in Georgia as a quickly weakening minimal hurricane, bringing a 3–5 ft (0.9–1.5 m) storm surge and heavy surf. Its inner core remained away from major cities, though Savannah recorded sustained winds of 58 mph (93 km/h) and wind gusts of 68 mph (109 km/h). Although no major damage occurred in Savannah, high winds downed numerous power lines, leaving approximately 70,000 electrical customers without power, some for up to two weeks after the storm. Many trees were downed along downtown streets. Tybee Island and its vicinity may have experienced hurricane-force wind gusts. Several homes on the island were partially deroofed. In Darien, the storm severely damaged a nursing home, flooded some streets, and downed tree limbs. Offshore, strong seas disrupted a portion of the coastal reef by moving a sunken ship 300 ft (90 m). Tides produced by the storm also inundated the Jekyll Island Causeway and the F.J. Torras Causeway, which links Brunswick to St. Simons Island. Overall, David was responsible for approximately $5 million in damage
