A tornado was reported on the ground near Fort Lauderdale airport and Interstate 595, the National Weather Service said.
Florida residents posted frightening footage of a tornado on the coast as weather from Hurricane Irma begin to rage the region.
Hurricanes and tropical storms, collectively known as tropical cyclones, provide all the necessary ingredients to form tornadoes. First, most hurricanes carry with them individual supercells, which are rotating, well-organized thunderstorms. These are typically the storms that spin up monster twisters in the Plains. All tornadoes need thunderstorms to form, said Brian McNoldy, a researcher at the University of Miami.
Hurricanes often form tornadoes through the creation of well-organised thunderstorms, instability in the atmosphere and increases in wind speed, which all combine to whip up the violently rotating winds.
Witnesses described the natural phenomenon as occurring near the beaches of Fort Lauderdale.
The National Hurricane Center, who told residents via twitter “heavy Squalls with embedded tornadoes” were “sweeping Across South Florida”.
