JACKSON COUNTY, Ark. (KTHV) -When Jackson County was in the midst of a tornado warning Tuesday night, the siren failed to operate. Emergency workers said a computer glitch is likely to blame.

Region 8 News reported that the Sheriff's Office tests the system silently every night using a remote to send a signal to the Jackson County Office of Emergency Management.

Sheriff David Lucas said emergency workers could not activate it manually either.

"We just went into what I would call a recovery mode to try to figure out 'Okay, they're not working. What do we need to do to get the word out?'" explained Lucas.

The sheriff sent out deputies to warn people using sirens from their patrol cars as well as alerting media.

A technician is expected to come as early as Friday to inspect the entire system.
