El Niño Creates More Favorable Conditions for Winter Tornadoes in Florida

A strong El Niño may raise the chances for an above-average tornado season this winter in Florida, according to meteorologists at the National Weather Service.
The Tallahassee office of the NWS says El Niño is known to push severe weather south in the winter, which leaves central and southern Florida in the bull's-eye. Upon studying El Niño years and otherwise, the NWS found a higher likelihood of tornadoes from November through April than with any other pattern.

The period from November 1997 through April 1998, influenced by one of the strongest El Niño events in recent memory, produced 43 tornadoes in Florida, which the NWS says was the worst year since records began. Of those 43 twisters, seven were at least F3 strength (this was before the Enhanced Fujita Scale was adopted).
