Hurricane Bob (1985)
Hurricane Bob was a hurricane that affected the southeast United States in July 1985. The second tropical storm and first hurricane of the 1985 Atlantic hurricane season, the system developed from a tropical wave on July 21 in the eastern Gulf of Mexico. Bob began moving east, striking southwestern Florida as a weak tropical storm. The storm then turned to the north and quickly intensified to hurricane status on July 24. The next day, it made landfall near Beaufort, South Carolina, becoming one of a record-tying six hurricanes to hit the United States during a single season. Bob quickly weakened over land, and was absorbed by a frontal trough over eastern West Virginia on July 26.
Bob caused $20 million in damage as well as five indirect deaths. In Florida, the storm produced heavy rainfall, peaking at over in Everglades City. In most areas, the rainfall was beneficial due to dry conditions that had persisted throughout the year. Damage was minimal in South Carolina, where the hurricane made its final landfall. In Virginia, the storm spawned three tornadoes, one of which destroyed two houses.
==Meteorological history==
The remnants of a tropical wave entered the eastern Gulf of Mexico on July 20. An area of low pressure formed and developed into a tropical depression on July 21. Under weak steering currents, the tropical depression drifted southeast, then turned northeast and later east. Based on reports from Hurricane Hunters, the system intensified into Tropical Storm Bob late on July 22. Bob failed to organize significantly as it tracked east through the Gulf, and made landfall between Naples and Fort Myers, Florida on July 23 as a tropical storm. At the time, most of the convection was concentrated south and east of the center.
While moving across Florida, Bob turned to the northeast, then to the north. It subsequently left the peninsula, entering the Atlantic Ocean near Vero Beach early on July 24. As it moved over the warm waters of the Gulf Stream, it quickly organized and intensified into a Category 1 hurricane while east of Jacksonville, Florida.〔 Because it was embedded within the western extension of the subtropical ridge, Bob retained higher-than-average atmospheric pressures throughout its lifespan. The hurricane continued north, and made landfall near Beaufort, South Carolina early on July 25 while maintaining winds of . Bob quickly weakened over land, decaying into a tropical storm three hours after landfall.〔 About 12 hours later, it degenerated into a tropical depression near the North Carolina – Virginia border. Bob's remnants turned north-northeast, and were absorbed by a frontal trough over eastern West Virginia on July 26.〔 An associated area of disturbed weather remained separate from the trough, and continued northeast through the Mid-Atlantic and New England.
