Tornado sirens briefly sounded off in Sheboygan County during Monday's thunderstorms.
But there was no tornado.
"We had heavy thunderstorms come through Sheboygan and the tornado siren was activated," said Sheboygan Fire Chief Mike Romas via email.
Sheboygan County dispatch referred questions about how the sirens were activated, and how many went off, to the sheriff's department.
Romas said more information may be available Tuesday.
Sarah Wieberdink said she heard the sirens from in front of her Sheboygan Falls apartment.
"I have a fear of being in a tornado. I've never been in one," she said. "So I have this huge fear, and I was thinking, 'Oh my gosh, is this really going to happen?' I didn't know what was going on."
Wieberdink said her friends across Sheboygan County also reported hearing the sirens.
"On Twitter, and Facebook, people who live in the area were talking about it," Wieberdink said. "A lot of people were confused."
She thinks the sirens were activated around 2 p.m., and that the noise only lasted for minutes.
Wieberdink said she bears no ill will towards Sheboygan County Dispatch and the person, or people, who may have activated the sirens.
"Mistakes happen," Wieberdink said. "If it were to happen again I'd say, alright, this is a little carried away. But one time is not a big deal."
