Lightning strike causes tornado siren malfunction

NORTH LIBERTY (KWWL) -- Lightning hit a siren in North Liberty and caused it to sound on Friday afternoon.

It happened around 2:30 p.m. Friday afternoon to an outdoor warning siren located at 2230 St. Andrews Drive. The area was under a Severe Thunderstorm Warning at the time, but the city says the siren malfunctioned and was not supposed to go off.

Maintenance crews pulled power to the siren and its backup system to stop the malfunction.

The city plans to repair the siren next week. The siren will not be used until after repairs are finished. It is one of six sirens in the city, and one of 51 sirens throughout Johnson County.

Dave Wilson, the Johnson County Emergency Management Coordinator says the situation is uncommon, but does happen from time to time. He said the sirens have lightning and electrical surge protection, but those precautions are no match for a direct lightning strike.
