A strong El Niño that began in June has already fueled record heat and suppressed hurricane activity, and forecasters believe it could still strengthen into one of the most powerful versions ever recorded.
If that happens, Florida — including Northeast Florida — could be in for a cooler, wetter winter marked by stronger storms and higher tornado risk, bringing both drought relief and new concerns for households, Jacksonville Today reported.
Here's what to know
Meteorologists around the state acknowledge the current pattern is still in an early phase even though it already qualifies as a moderate El Niño.
Stephen Shiveley, a meteorologist with the National Weather Service in Ruskin, explained that El Niño is linked to warmer-than-normal Pacific waters.
Though it develops far from Florida, it can still influence winter weather by altering the atmosphere.
Chief Meteorologist Mike Clay with Spectrum Bay News 9 noted that the phenomenon does not guarantee one specific outcome, but it can change the odds of certain weather patterns.

"Areas that don't normally get rain will get rain," Clay said. "Areas that normally get rain will be in a drought."
Andrew Wulfeck, a meteorologist with the Florida Public Radio Emergency Network, warns that the forecast is stronger than any El Niño outlook he has seen, and he expects Florida to face severe weather this winter.
More background
Florida has been plagued by severe drought this year.
Across the 16 counties covered by the Southwest Florida Water Management District, rainfall in June, July, August, and September — normally wet months — was below average.
A rainier winter could help replenish water supplies and reduce concern about water restrictions scheduled to expire on Oct. 1.
But the same setup can also make dangerous weather more likely, especially in Central and South Florida.
Clay indicated that El Niño years often bring a higher tornado threat, with those parts of the state frequently recording twice as many tornadoes.
"Every significant tornado that's ever hit the peninsula of Florida has been during an El Niño," he added.
As noted by Jacksonville Today and the National Weather Service, one of the strongest El Niño events was connected to Central Florida's 1998 tornado outbreak, the deadliest in state history, which killed 42 people.
Clay also said Tampa got 14 inches of rain in December 1997.
What can be done?
A wetter, stormier winter can mean more severe weather alerts and longer bouts of heavy rain.
Florida homes are typically designed for summer cooling, but a cooler, damper winter can increase demand for heating, drying clothes, and running dehumidifiers, which could push utility bills higher for some families.
More rainfall could provide meaningful drought relief, as Southwest Florida Water Management District official Susanna Martinez Tarokh observed.
"Given consistent, below-average rainfall, we need consistent above-average rainfall to relieve the long-term deficit," Tarokh said.
"We're trading out the dry conditions for more wet conditions, stormier conditions, likely when we turn the calendar year," Wulfeck remarked.
