New York City was under a tornado warning Tuesday, leaving many to wonder what was going on.

News 12 meteorologists say instead of a tornado, New York City actually experienced a “Gustnado.”

The gustnado caused heavy rain and strong winds that teared through the city. The whirlwind thunderstorm was seen moving over the Harlem River affecting neighborhoods in Manhattan, the Bronx and even New Jersey.

News 12 Meteorologist Mike Rizzo says the difference between a tornado and a gustnado is that a gustnado is a whirlwind formed by fast moving air sinking to the ground at the leading edge of a thunderstorm.

He says although they are not tornadoes, they can still have a swirling motion.

The National Weather Service confirmed a gustanado with winds of 70 to 75 mph moving from the Harlem River to north of Fordham Road.

No one was reported hurt during the gustnado.
