Hurricane Elena, an unpredictable and damaging tropical cyclone that affected eastern and central portions of the United States Gulf Coast, made landfall near Biloxi, Mississippi, as a Category 3 major hurricane.

Hurricane Elena was a strong, destructive and erratic tropical cyclone that affected eastern and central portions of the Gulf Coast of the United States in late August and early September 1985. Threatening popular tourist destinations during the Labor Day weekend, Elena repeatedly deviated from its forecast path, triggering evacuations of unprecedented extent. The hurricane wrought havoc to property and the environment between southwestern Florida and eastern Louisiana, though lesser effects were felt well beyond those areas. Elena developed on August 28 near Cuba, and after traveling lengthwise across the island with little impact, it entered the Gulf of Mexico and continued to strengthen. Initially projected to strike the central Gulf Coast, the hurricane unexpectedly veered toward the east on August 30, then stalled just 50 mi (80 km) west of Cedar Key, Florida. Despite predictions that Elena would continue eastward across Florida, the cyclone remained nearly stationary for about 48 hours, causing damage all along the eastern gulf with high winds and waves, before slowly moving northwest and ultimately making landfall near Biloxi, Mississippi, on September 2 as a Category 3 major hurricane. The storm quickly weakened upon moving ashore and dissipated on September 4.
