Wind gusts near 80 mph flipped cars, snapped trees along Frantz Road and Emerald Parkway, and knocked out power across the Dublin area on Aug. 11. But the tornado sirens never went off.
Franklin County Emergency Management & Homeland Security confirmed the reason: the National Weather Service never issued a tornado warning for Franklin County that day. Without that specific alert, the sirens stay silent.
The distinction matters. Franklin County was under a severe thunderstorm watch and flash flood warnings for most of Aug. 11, according to NBC4. Those are serious alerts, but they do not meet the threshold that triggers the county's siren system.
Neighboring Madison County did receive a tornado warning after NWS radar detected rotation near Cedarville around 2:30 p.m. That warning activated Madison County's sirens. Franklin County's weather picture, while destructive, did not show the same rotation signatures.
What's the difference?
A tornado watch means atmospheric conditions could produce a tornado. A tornado warning means one has been spotted or is expected imminently. Only a warning triggers Franklin County's sirens.
NBC4 meteorologist Dave Mazza explained that tornadoes pull air inward and upward, creating a distinct damage pattern different from straight-line winds. "Tornadoes have a sucking effect on the ground, pulling air inwards and upwards," Mazza said, contrasting them with microbursts, which push air downward and outward. The NWS recorded an 82 mph gust at John Glenn Columbus International Airport on Aug. 11, and a WOSU report confirmed the weather service acknowledged high-wind damage in Dublin specifically.
A National Weather Service spokesperson told WOSU that surveyors may be sent out to determine whether a tornado actually touched down in the area. No official determination had been made as of Aug. 12.
Dublin damage without a warning
Storm damage in Dublin on Aug. 11 stretched across Frantz Road, Emerald Parkway, Muirfield Drive, State Route 33 and Shier Rings Road near Shamrock Court, where a tree fell across a parking lot. AEP Ohio reported more than 130,000 customers without power across its service area by 1:30 p.m. that day. The Franklin County Auditor's office confirmed the county received several inches of rain with wind gusts around 80 mph on Aug. 10 and 11.
As we reported Aug. 11, Franklin County Auditor Michael Stinziano said homeowners with storm-damaged properties may qualify for a temporary reduction in assessed value.
