On March 17, 1983, a significant severe weather event affected the southern Florida peninsula, including the Miami metropolitan area. A total of at least five tornadoes affected the region; while as many as 17 were reported, only two were confirmed in the official National Weather Service records. The strongest tornado produced F2 damage on the Fujita scale and skipped across the Everglades region from the eastern Big Cypress National Preserve through the Everglades and Francis S. Taylor Wildlife Management Area to Lighthouse Point—a path length of nearly . An F1 tornado also affected Naples and Golden Gate. Additionally, unconfirmed tornadoes affected an RV park southeast of East Naples, as well as the Stuart and Jupiter areas, respectively. In addition to tornadoes, severe thunderstorms produced hail to in diameter, as well as rainfall totals of in some areas. Background On Thursday, March 17, 1983, surface weather analysis indicated that a large and intense low-pressure area over the Gulf of Mexico was producing gale-force winds over the southern Florida peninsula. Above the surface, a strong low-level jet stream coupled with a large negative geopotential height—with heights measuring standard deviations below normal—produced sufficient lifting and wind shear, both conditions conducive to severe weather. Due to the favorable conditions for severe weather, the National Weather Service office in Miami issued a tornado watch for South Florida, effective the morning of March 17. The watch was canceled at 9:30 a.m. EST (14:30 UTC), but then was reissued and extended to 5:00 p.m. (22:00 UTC) as more storms formed over the Everglades. Forecasters expected the low pressure area in the Gulf of Mexico to bring a cold front across Florida on Friday, March 18. The tornadoes occurred during a strong occurrence of El Niño—a condition known to enhance severe weather over Florida. Confirmed tornadoes At least three unconfirmed tornadoes were reported, two of them in Martin County: •A tornado reportedly affected the Hitching Post RV Travel Resort, near Naples Manor, causing $6,000 in damage to one trailer, tearing loose a carport from another, and felling trees and utility lines. Electricity was disrupted for four hours, leaving 300 residents powerless. •Another possible tornado about 8:20 a.m. (13:20 UTC) overturned a vehicle on the Bee-Line Highway north of Indiantown Road, west of Jupiter, injuring one woman. The person was transported to a hospital, where she was treated and released. •A third possible tornado touched down around 8:35 a.m.
