 Brief Description: A multivortex tornado touched down just west of U.S. 1 near mile marker 100. The tornado moved north northeast at 30 mph passing across ten housing subdivision, mostly mobile home parks. It damaged about 600 structures, tore down utility lines, damaged vessels and destroyed a great deal of foliage. The tornado crossed to the east of U.S. 1 near the intersection of Highway 905, overturning a semi tractor trailer, and continue north northeast for about six miles damaging house roofs and foliage. Tropical storm Mitch, after devastating portions of central America as a hurricane then dissipating over land, reformed over the Bay of Campeche and moved northeast across the Yucatan Peninsula, the southeast Gulf of Mexico and into south Florida. Casualties in south Florida included two drownings in a fishing boat that capsized near the Dry Tortugas and about 65 injuries, most of them minor, in the upper keys involving hurricane spawned tornadoes. Losses are estimated at $50 million, including $20 million in crop damage. Much of the property damage was caused by five tornadoes, one of which reached a maximum intensity of F2, in the upper Keys. A total of 646 dwellings were damaged in an area from Islamorada to north Key Largo. Other tornadoes were observed in Broward, Palm Beach, and Collier counties. Widespread rainfall totals across south Florida averaged 6 to 8 inches with local amounts of 13 inches. The storm surge of 2 to 4 feet along the Keys and southwest Florida coast, and 1 to 2 feet along the southeast coast, produced minor flooding, beach erosion and damage to marine structures and vessels.
