On Tuesday, February 23, 1965, a small, localized tornado outbreak affected southern portions of the U.S. state of Florida. At least four confirmed tornadoes touched down between 10 a.m.–1 p.m. EST (15:00–18:00 UTC); the strongest tornado moved through the Fort Lauderdale area and produced F3 damage on the Fujita scale, injuring six people. In addition, an F1 tornado also moved through northern Broward and southern Palm Beach counties. Two tornadoes also affected Lee County, producing F2 and F1 damage, respectively.[nb 2][nb 3][nb 4]

  • A tornado reportedly damaged three residences in a pair of duplexes in Lehigh Acres, injuring a person with airborne glass, flaying the paint on a vehicle with pebbles, pulling up roofing, and scattering TV antennae, garbage cans, and awnings. However, this was officially classified as a severe thunderstorm wind.[14]

This tornado produced intermittent, minor damage, mainly to trees and fences. A small, rural barn was destroyed as well. Losses totaled $2,500.[16][17][18][19][20]
F3 Southwestern Fort Lauderdale to southeastern Oakland Park Broward FL 26°06′N 80°10′W / 26.10°N 80.17°W / 26.10; -80.17 (Fort Lauderdale (February 23, F3)) 16:15–? 5.7 mi (9.2 km) 60 yd (55 m) $250,000

This tornado substantially damaged saran housing and vegetation at a plant nursery. A mother and infant were injured in a trailer. Losses totaled $25,000.[21][22][23][19]
F2 Fort Myers Lee FL 26°37′N 81°52′W / 26.62°N 81.87°W / 26.62; -81.87 (Fort Myers (February 23, F2)) 17:45–? 0.5 mi (0.80 km) 67 yd (61 m) $25,000
Various structures and small homes were either partly unroofed or extensively damaged. A metal structure at a factory was damaged, skylights and windows were smashed, a built-up roof was mostly pulled off its sheathing, a shed and awnings were blown away, a carport was shifted, and a pair of trucks were tipped sideways. Additionally, a 40-foot-long (13 yd), 12-foot-tall (4.0 yd) CMU wall was downed, while a similar but smaller wall elsewhere was bent 2 ft (0.67 yd) outward. Losses totaled $25,000. Grazulis did not list this tornado as an F2 or stronger.[24][21][22][25][19][26]

The second tornado touched down near Chula Vista and moved north-northeast across western portions of the city of Fort Lauderdale, affecting a 1-square-mile (2.6 km2) area, or 40 blocks, of the city. The small funnel was visible from a jetliner awaiting takeoff at Fort Lauderdale International Airport. Later, it briefly lifted prior to touching down in Oakland Park, and it dissipated northeast of Wilton Manors. Though three funnel clouds occurred along the path, only one tornado developed. One home was destroyed, while seven trailers, three cars, and a pair of trucks received severe damage. Most of the damage affected a marina and a trailer park, though damage to power poles left about 2,400 residents powerless. 75 small watercraft were damaged at the marina, along with the clubhouse. The width of the damage path averaged 60 yd (180 ft), but occasionally reached 100 yd (300 ft). The tornado caused six injuries, three of them due to airborne debris, and at least $140,000–$300,000 in damages (NCEI lists damages as $250,000). The tornado is officially estimated to have been an F3 event. It remains the second of only three F/EF3 tornadoes to affect Broward County since 1950; the others occurred on April 10, 1956, and March 1, 1980. However, tornado researcher Thomas P. Grazulis classified the tornado as an F2.[27]

Non-tornadic effects

In addition to tornadoes, multiple funnel clouds occurred over at least two counties in southern Florida, and at least one waterspout touched down near West Palm Beach.[19]

Notes

  1. ^ All losses are in 1965 USD unless otherwise noted.
  2. ^ An outbreak is generally defined as a group of at least six tornadoes with no more than a six-hour gap between individual tornadoes; however, the threshold varies slightly according to local climatology. On the Florida peninsula, an outbreak consists of at least four tornadoes occurring relatively synchronously—no more than four hours apart.[2][3][4][5][3]
  3. ^ The Fujita scale was devised under the aegis of scientist T. Theodore Fujita in the early 1970s. Prior to the advent of the scale in 1971, tornadoes in the United States were officially unrated.[6][7] While the Fujita scale has been superseded by the Enhanced Fujita scale in the U.S. since February 1, 2007,[8] Canada used the old scale until April 1, 2013;[9] nations elsewhere, like the United Kingdom, apply other classifications such as the TORRO scale.[10]
  4. ^ Historically, the number of tornadoes globally and in the United States was and is likely underrepresented: research by Grazulis on annual tornado activity suggests that, as of 2001, only 53% of yearly U.S. tornadoes were officially recorded. Documentation of tornadoes outside the United States was historically less exhaustive, owing to the lack of monitors in many nations and, in some cases, to internal political controls on public information.[11] Most countries only recorded tornadoes that produced severe damage or loss of life.[12] Significant low biases in U.S. tornado counts likely occurred through the early 1990s, when advanced NEXRAD was first installed and the National Weather Service began comprehensively verifying tornado occurrences.[13]
  5. ^ All dates are based on the local time zone where the tornado touched down; however, all times are in Coordinated Universal Time and dates are split at midnight CST/CDT for consistency.
  6. ^ Prior to 1994, only the average widths of tornado paths were officially listed.[15]
