of just above the surface, and thereby yielded conducive conditions to tornadogenesis. During the evening and the overnight hours of February 22–23, 1998, this volatile environment—known to be common in the El Niño phase of the El Niño–Southern Oscillation (ENSO) during the Florida dry season (November 1 – April 30)—eventually produced seven tornadoes between about 11:00 p.m. EST on February 22 and 2:30 am. EST on the following morning. During El Niño the jet stream is typically stronger and displaced southward near or over Florida during meteorological winter and spring, thereby augmenting the likelihood of significant severe weather and tornado activity. During February 1998 one of the strongest El Niño episodes on record was ongoing, rivaling a similar episode in 1982–3 that had also contributed to elevated tornado activity over Florida. By October 1997, the National Weather Service (NWS) in Melbourne, Florida, highlighted the potential for enhanced severe weather over the coming months due to El Niño. By 6:00 am. EST (11:00 UTC) on February 22, the Storm Prediction Center (SPC) had issued a convective outlook for day one indicating a moderate risk of severe thunderstorms capable of producing tornadoes over portions of North and Central Florida. At 11:55 am. EST (16:55 UTC), the NWS in Melbourne also issued a Hazardous Weather Outlook (HWO) highlighting a "significant" threat of tornadoes, hail, and destructive winds. By 1:44 pm. EST (18:44 UTC), the SPC issued its first tornado watch covering portions of the threatened area in Central Florida. Numerous, long-lived supercells with persistent mesocyclones would eventually evolve during the evening and track generally east-northeastward or northeastward over Central Florida, generating tornadoes that killed 42 people and seriously injured at least 259 others, making the outbreak the deadliest in Florida's history, surpassing another that killed 17 people on March 31, 1962, in Santa Rosa County. Outbreak statistics Confirmed tornadoes February 21 event February 22 event February 23 event Intercession City–Campbell–Poinciana–Kissimmee–Buenaventura Lakes–Lake Hart–Lake Mary Jane, Florida This devastating, long-tracked tornado was initially assigned an F4 rating, but NWS assessments later reduced this to high-end F3 intensity. The tornado began near Intercession City, only southeast of Walt Disney World, and moved northeastward. It first did some minor damage to homes in the Campbell–Poinciana area. As it moved into Kissimmee, it leveled part of The Shops at Kissimmee shopping center and crossed the northern part of Lake Tohopekaliga. The tornado subsequently crossed U.S. Route 441 and
