Tropical Storm Harvey was a moderately strong tropical storm that caused flooding across south Florida during the 1999 Atlantic hurricane season. The tenth tropical cyclone and eighth named storm of the season, Harvey developed from a tropical wave in the Gulf of Mexico on September 19. After forming, the system gradually intensified and became a tropical storm early on September 20. Throughout the rest of its duration, Harvey slowly intensified as it headed eastward. Late on September 21, Harvey made landfall in Southwest Florida with winds of 60 mph (95 km/h). Harvey emerged into the Atlantic early on September 22, but was absorbed by an extratropical cyclone. The remnants of Harvey reached Atlantic Canada before dissipating.
Harvey caused minor flooding in south Florida because of light to relatively heavy rainfall in that portion of the state and at least 34 houses and businesses in southern Florida were flooded. There were sporadic reports of tropical storm-force winds throughout the state, as well as two tornadoes. Damage estimates in Florida reached about $15 million (1999 USD). Throughout the rest of the United States, impact was limited, confined to light rainfall in Georgia, North Carolina and South Carolina. Heavy rainfall was reported in Atlantic Canada and Harvey became the wettest tropical cyclone on record in that country. Significant flooding, especially to roads and houses, was reported due to the heavy rainfall and damage throughout Atlantic Canada totalled several million dollars.
A tropical wave emerged from the west coast of Africa on late on September 4, 1999 and entered the Atlantic Ocean. The system trekked westward uneventfully and was unable to organize itself due to the influence of outflow from Hurricane Floyd. After Floyd moved northward, however, the system began developing convection as it traversed the Caribbean Sea. By September 16 the disturbance transitioned into a broad area of low pressure while tracking northwestward in the western Caribbean Sea. After two days the low had continued to intensify as it entered the southern Gulf of Mexico. Thunderstorm activity continued to increase in association with the weather system and a buoy in the eastern Gulf of Mexico recorded sustained winds of 35 mph (56 km/h). At 0600 UTC on September 19, the system finally developed into Tropical Depression Ten, while located approximately 400 miles (640 km) west-southwest of St. Petersburg, Florida. The National Hurricane Center initiated advisories on the depression approximately four hours later.
