ST. PETERSBURG, Fla. -- Tampa Bay's recent bout of severe weather, including one EF-1 tornado in Pasco County, comes a little more than a month after the last event.
And another could happen Friday. They say two's a coincidence, could three times be a trend?
Look halfway around the world to help answer that question: It's becoming increasingly likely El Niño will form this upcoming 2018-19 winter season, according to the latest Climate Prediction Center outlook.
 
El Niño is associated with a band of warmer than average water largely along the equator in the Pacific Ocean. La Niña is its opposite, with colder than average water.
Both affect weather patterns worldwide, including in Florida. El Niño tends to bring the greatest impacts, with above average precipitation and increased storminess with a subtropical jet stream parked over the region. An El Niño scenario also typically features storm tracks that are farther south than those during a La Niña year.
"El Niño events shift global weather patterns," 10Weather's Bobby Deskins said. "Here in Florida, that shift means the southern jet stream moves over us. That stream not only brings storms to us, but the winds associated with it aloft help to make those storms stronger."
