Despite tornado sirens sounding for millions, a storm did not produce a tornado over Columbus, Ohio, on Wednesday morning.
The alarms were part of the annual Ohio Statewide Tornado Drill, according to a Special Weather Statement issued by the National Weather Service in Cleveland. NWS meteorologist in charge David Bieger, who works at the Cleveland office, told Newsweek that the state determines the date for the statewide test.
"If we anticipate severe weather or there is severe weather ongoing, we will cancel and reschedule," Bieger said. "You never want to be in a situation where you're creating any sort of confusion with the public or emergency management when you do issue these drills."

At 9:51 a.m. ET, the NWS sent a message to every county in Ohio clearly marked as a test, activating the statewide drill. The alert—designed to mimic a real tornado warning—remains one of the key tools used by emergency managers to ensure residents know how to respond during severe weather.
“TEST. TEST. TEST. The National Weather Service in Cleveland OH has issued a TEST message for the Ohio Statewide Tornado Drill,” the statement said. “There is no severe weather occurring at this time.”

The drill prompted outdoor warning sirens, NOAA Weather Radio alerts, and in some cases, mobile notifications. The annual event is coordinated by the NWS, the Ohio Emergency Management Agency, and the Ohio Committee on Severe Weather Awareness, which encourages schools, businesses, and households to use the time to review their tornado safety procedures.
The message emphasized that in a real severe weather event, the NWS would issue a specific warning with details about the threat, such as rotation on radar or reports of a tornado on the ground.
The drill concluded at 10 a.m., and the NWS reiterated multiple times that the alarm was only a test. There were no storms in the area, and no tornado warnings or tornado activity occurred anywhere near Columbus during the exercise.
Emergency officials say statewide drills are essential as Ohio approaches peak severe weather season—typically from March through June—when fast‑forming storms can develop with little notice.
The drill comes after severe weather has already torn across the region this spring. Storms from March 11 produced three EF0 tornadoes between Shelby County and Auglaize County, NWS Wilmington confirmed, with all twisters occurring within minutes of each other at around 10:20 a.m. An EF0 is considered a weak tornado, with winds between 65 and 85 mph.
How Does a Tornado Form?
A tornado forms when warm, moist air near the ground collides with cooler, drier air above, creating instability that fuels a strong thunderstorm. If winds at different altitudes blow at varying speeds or directions, they generate wind shear, which can cause air to spin horizontally until a powerful updraft inside the storm tilts that spinning air vertically, forming a rotating core. As this rotation tightens and intensifies, pressure drops, moisture condenses into a funnel cloud, and once that rotating column of air reaches the ground—often marked first by swirling debris—a tornado has officially formed.
